Questions: Part A The process of cellular respiration, which converts simple sugars such as glucose into CO2 and water, is an example of - an endergonic pathway - a pathway that converts organic matter into energy - a catabolic pathway - a pathway in which the entropy of the system decreases - a pathway that occurs in animal cells but not plant cells

The answer is the third one: a catabolic pathway.

Explanation for each option:

1. An endergonic pathway: This is incorrect. An endergonic pathway requires an input of energy to proceed, whereas cellular respiration releases energy.

2. A pathway that converts organic matter into energy: This is partially correct but not the best description. Cellular respiration converts the chemical energy stored in glucose into ATP, a more usable form of energy for the cell, but it doesn't convert matter into energy in the sense of mass-energy equivalence (E=mc²).

3. A catabolic pathway: This is correct. Cellular respiration is a catabolic pathway because it involves the breakdown of glucose into smaller molecules (CO₂ and water), releasing energy in the process.

4. A pathway in which the entropy of the system decreases: This is incorrect. In cellular respiration, the entropy of the system actually increases as glucose is broken down into smaller molecules, which is a more disordered state.

5. A pathway that occurs in animal cells but not plant cells: This is incorrect. Cellular respiration occurs in both animal and plant cells, as both types of cells require energy in the form of ATP.

In summary, cellular respiration is best described as a catabolic pathway.
