Question

The process of cellular respiration, which converts simple sugars such as glucose into CO2 and water, is an example of __________.
(i)-a pathway in which the entropy of the system decreases
(ii)-a catabolic pathway a pathway that converts organic matter into energy
(iii)-a pathway that occurs in animal cells but not plant cells an endergonic pathway

Answer 1

Answer:

ii) A catabolic path way.

Explanation:

There are two types of respiration:

1. Aerobic respiration  

2. Anaerobic respiration

Aerobic respiration

It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.

Glucose + oxygen → carbon dioxide + water + 38ATP

Anaerobic Respiration

It is the breakdown of glucose molecule in the absence of oxygen and produce small amount of energy. Alcohol or lactic acid and carbon dioxide are also produced as byproducts.  

Glucose→ lactic acid/alcohol + 2ATP + carbon dioxide

This process use respiratory electron transport chain as electron acceptor instead of oxygen. It is mostly occur in prokaryotes. Its main advantage is that it produce energy (ATP) very quickly as compared to aerobic respiration.
