ATP(adenosine tri-phosphate) stores energy between it's 2nd and 3rd phosphate groups. When the 3rd phosphate group is released ADP(adenosine mono-phosphate) is created and energy is being released. This molecule is important because it stores the energy from cellular respiration and most cellular processes require the energy released by ATP.

Chronic, throbbing, and long-lasting pain is primarily transmitted by (B) C fibers.

C fibers are a type of unmyelinated nerve fibers that have a slower conduction velocity compared to A-delta fibers, which are responsible for transmitting acute and sharp pain. C fibers are associated with dull, aching, and persistent pain sensations.

While A-delta fibers are involved in acute pain perception, they are not primarily responsible for transmitting chronic and long-lasting pain. Proprioceptors in the skin and joints, which are sensory receptors involved in providing information about body position and movement, are not directly involved in transmitting pain signals.

Therefore, the correct answer is B) C fibers.

Regarding mitochondria, the correct statements are - Powerhouse of the cell, Only organelle to use oxygen, Energy is released when C-C bonds of nutrients are broken, Converts pyruvate or acetyl CoA to CO2.

The mitochondrion is often referred to as the powerhouse of the cell because it plays a crucial role in generating cellular energy in the form of adenosine triphosphate (ATP) through the process of cellular respiration.

Mitochondria are the primary organelles involved in aerobic respiration, which requires oxygen as the final electron acceptor in the electron transport chain.

Mitochondria are not involved in photosynthesis. Photosynthesis occurs in chloroplasts in plant cells, while mitochondria are present in both plant and animal cells and are responsible for cellular respiration.

Mitochondria participate in the breakdown of nutrients, such as glucose, through a series of biochemical reactions, including glycolysis, the citric acid cycle (also known as the Krebs cycle), and oxidative phosphorylation.

During these processes, carbon-carbon (C-C) bonds are broken, releasing energy.

In the citric acid cycle, pyruvate, derived from glycolysis, is converted to acetyl CoA, which then enters the cycle. In this process, carbon dioxide (CO2) is released as a byproduct.

While plants utilize carbon dioxide from the air during photosynthesis, mitochondria do not directly utilize CO2 from the environment. They primarily use oxygen (O2) in cellular respiration.

Based on the correct statements, the options would be:  The powerhouse of the cell, the Only organelle to use oxygen, Energy is released when C-C bonds of nutrients are broken, and it Converts pyruvate or acetyl CoA to CO2.

The liver is in charge of metabolizing and detoxifying foreign substances, including medications, in the blood.

Numerous medicines are metabolised by the liver, and as a result, water-soluble molecules that can be eliminated in the bile are produced. This is the consequence of phase 1 reactions, such as oxidation, reduction, and hydrolysis reactions, which are mediated by cytochrome p450. Phase 2 reactions, which are conjugative, come next.

A class of enzymes known as cytochrome P450 performs oxidation and reduction activities (phase 1) using iron to increase the solubility of medicines in water, which helps with excretion. Because they are attached to cell membranes and have a haem pigment that absorbs light at a wavelength of 450 nm when exposed to carbon monoxide, CYP450 enzymes get their name.

The tendon reflex can be matched with option b, which causes muscle relaxation and lengthening in response to tension.

The tendon reflex, also known as the stretch reflex or myotatic reflex, is a spinal reflex that helps maintain muscle tone and prevent overstretching of muscles. When a muscle is stretched, sensory receptors called muscle spindles within the muscle detect the change in muscle length and send signals to the spinal cord. The tendon reflex involves the activation of muscle spindles, which then trigger a reflex response.

Option b describes the tendon reflex accurately. When a muscle experiences tension, such as during a stretch, the muscle spindles are activated and send signals to the spinal cord. In response, the spinal cord stimulates the motor neurons of the muscle to contract, causing reflexive muscle relaxation and lengthening. This reflex helps protect the muscle from excessive stretching and maintains proper muscle tone.

The other options provided in the question refer to different spinal reflexes. Option A describes the plantar reflex, which tests the integrity of the spinal cord and causes a downward flexion of the toes.

(c)Low Temperature of the Reactants can decrease the rate of a chemical reaction.

How temperature effects the rate of a chemical reaction

Chemical reactions typically occur faster at higher temperatures. Food can spoil quickly when left on the kitchen counter. However, the lower temperature inside of a refrigerator slows that process so that the same food remains fresh for days. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision.Thus decrease in the temperature of a reaction can help in decreasing the rate of a chemical reaction.Lower the temperature lower the chemical reaction rate.

The vitamins that assist dehydrogenase enzymes and play a role in transferring hydrogens from energy-yielding compounds to oxygen in the metabolic pathways of the cell are Vitamin B2 (Riboflavin) and Vitamin B3 (Niacin). These vitamins act as cofactors for dehydrogenase enzymes, helping them to carry out their function in cellular metabolism.

Explanation:

What is dehydrogenase enzyme?

Dehydrogenase enzymes are the class of oxidoreductase enzymes that catalyze the removal of hydrogen from a substrate or the addition of hydrogen to a substrate. These enzymes are mostly involved in metabolic processes and play an important role in producing energy by removing hydrogens from energy-yielding compounds. The energy-yielding compounds include carbohydrates, proteins, and fats, which produce NADH (nicotinamide adenine dinucleotide) or FADH2 (flavin adenine dinucleotide) molecules during the metabolic process.

These NADH and FADH2 molecules are then used by dehydrogenase enzymes to produce ATP (adenosine triphosphate) through the electron transport chain.

Vitamins and dehydrogenase enzymes:

Niacin (vitamin B3) and riboflavin (vitamin B2) are two vitamins that play a role in the production of ATP by assisting dehydrogenase enzymes. Riboflavin is a precursor to the cofactor flavin adenine dinucleotide (FAD), which is used by succinate dehydrogenase, a complex II enzyme, and complex I enzyme in the electron transport chain.

Niacin, on the other hand, is a precursor to the cofactor nicotinamide adenine dinucleotide (NAD+), which is used by many dehydrogenase enzymes, including pyruvate dehydrogenase and the citric acid cycle enzymes. In conclusion, niacin and riboflavin assist dehydrogenase enzymes and play a vital role in transferring hydrogens from energy-yielding compounds to oxygen in the metabolic pathways of the cell.

According to the chapter, the answer is: 2. Isolation causes populations to diversify into a large number of species. When populations are isolated from each other, they can evolve independently, accumulating genetic differences over time.

This can lead to the development of new species with unique characteristics that are distinct from their ancestors. Isolation can occur in a variety of ways, such as geographic barriers, ecological differences, or reproductive barriers, and it can promote diversification and speciation.

Isolation plays a crucial role in shaping the evolution of species. There are different types of isolation that can affect populations, such as geographic isolation, temporal isolation, ecological isolation, and reproductive isolation.

Geographic isolation occurs when a physical barrier such as a mountain range, river, or ocean separates populations, preventing them from interbreeding. Over time, genetic differences can accumulate in each population, leading to the development of new species that are adapted to their specific environments.

Temporal isolation occurs when populations breed at different times, such as different seasons or times of day, which prevents them from interbreeding. This can lead to the formation of new species over time as each population adapts to its own unique breeding schedule.

Ecological isolation occurs when populations occupy different ecological niches or habitats, preventing them from interbreeding. This can lead to the development of new species as each population adapts to its own ecological niche.

Reproductive isolation occurs when populations are unable to interbreed due to differences in reproductive structures or behaviors. For example, two populations of birds may have different songs or courtship displays that prevent them from interbreeding, leading to the formation of new species over time.

When people exercise strenuously, their muscles rely primarily on anaerobic respiration for energy production due to the increased demand for energy that cannot be met solely by aerobic respiration. Anaerobic respiration, specifically lactic acid fermentation, occurs in the cytoplasm of the muscle cells and does not require oxygen. This process produces lactic acid as a byproduct, which can cause muscle pains experienced by the runners after strenuous exercise.

When the runners slow down or stop exercising, their bodies can transition back to aerobic respiration, which takes place in the mitochondria and requires oxygen. Aerobic respiration is more efficient in producing energy (in the form of ATP) and does not produce lactic acid as a byproduct. Thus, during periods of rest or reduced intensity exercise, the muscle cells rely on aerobic respiration for their energy needs, and the lactic acid can be cleared from the muscles, reducing the pain experienced by the runners.
