Question

The net effect of the eight steps of the citric acid cycle is to: A) Completely oxidize an acetyl group to carbon dioxide. B) Convert pyruvate to succinate. C) Produce NAD+ and Q. D) Produce 8 ATP for every pass through the cycle.

Answer 1

The net effect of the eight steps of the citric acid cycle is to completely oxidize an acetyl group to carbon dioxide.

Step-by-step explanation:

Cellular respiration has three main stages: glycolysis, the Krebs cycle (also called the citric acid cycle) and oxidative phosphorylation.

The Krebs cycle releases energy through the oxidation of the acetyl group in acetate derived from foods (i.e., carbohydrates, fats, and proteins), producing carbon dioxide (CO2) as a byproduct of these reactions.

Glycolysis occurs in the cytoplasm, while the Krebs cycle and oxidative phosphorylation occur in the mitochondria.

In conclusion, the net effect of the eight steps of the citric acid cycle is to completely oxidize an acetyl group to carbon dioxide.
