Question

Which of the following steps or processes in aerobic respiration include the

production of carbon dioxide?
(a) breakdown of glycogen
(b) glycolysis
(c) conversion of pyruvate to acetyl CoA
(d) oxidative phosphorylation

Answer 1

Glycolysis, conversion of pyruvate to acetyl CoA, and oxidative phosphorylation are steps in aerobic respiration that include the production of carbon dioxide.

Step-by-step explanation:

Aerobic respiration is a process that breaks down glucose and releases carbon dioxide and water. The steps or processes in aerobic respiration that include the production of carbon dioxide are:

1. Glycolysis: In this step, a molecule of glucose is split into two three-carbon molecules called pyruvate. Each pyruvate molecule is then converted to acetyl CoA, which releases carbon dioxide as a byproduct.
2. Conversion of pyruvate to acetyl CoA: This step involves the transformation of pyruvate into an acetyl group that will be picked up and activated by coenzyme A (CoA). During this conversion, carbon dioxide is released.
3. Oxidative phosphorylation: This step occurs in the inner membrane of the mitochondrion, where electrons extracted from food move down the electron transport chain. As the electrons move, they lose energy, which is used to phosphorylate AMP to make ATP. Carbon dioxide is produced as a byproduct of this process.
