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

Step-by-step explanation:

Aerobic respiration includes several steps or processes that produce carbon dioxide. The breakdown of glycogen does not directly produce carbon dioxide. Glycolysis, the conversion of pyruvate to acetyl CoA, and oxidative phosphorylation all involve the production of carbon dioxide. During glycolysis, glucose is split into two molecules of pyruvate, which are then converted to acetyl CoA in the mitochondria. In the process of oxidative phosphorylation, the electrons extracted from food move down the electron transport chain, resulting in the production of carbon dioxide as a waste product.
