Question

1. Which of the following molecules is broken down in cellular respiration, providing fuel for the cell?

Answer 1

1. Cellular respiration is a metabolic pathway that occurs inside the cell. During cellular respiration, glucose molecule is broken down in the presence of oxygen.

2. During cellular respiration, ATP (Adenosine Triphosphate) molecule is also produced that acts as energy currency and directly powers cell work.

3. Amylase is an enzyme that helps in digestion. It catalyzes the hydrolysis of starch into simple sugars. If amylase is present in normal amount it will break down starch into disaccharides. If the amount of disaccharidase amount is less than usual then less disaccharides will be broken down into monosaccharides. Thus the production of monosaccharides will decrease.

4. In the reactions shown above, the end product is largely dependent on the last enzyme. If Enzyme3 is in less amount than usual then there will be greatest reduction in the production of G and H. This is because the formation of product in any reaction is dependent on the substrate concentration and enzyme concentration.
