Chapter 23, Problem 23.72EP

(a)

Interpretation Introduction

Interpretation: To list the steps, by number in the citric acid cycle that involves oxidation and decarboxylation.

Concept introduction: Citric acid cycle is the third stage of the biochemical energy production process. The cycle includes the reactions in which the acetyl part of acetyl CoA is oxidized and leads to the formation of carbon dioxide and $\text{CoA-SH}$. An overview of the citric acid cycle is as follows:

Oxidation and decarboxylation step involves simultaneous oxidation and decarboxylation to produce the product.

(b)

Interpretation Introduction

Interpretation: To list the steps, by number in the citric acid cycle that involves phosphorylation.

Concept introduction: Citric acid cycle is the third stage of the biochemical energy production process. The cycle includes the reactions in which the acetyl part of acetyl CoA is oxidized and leads to the formation of carbon dioxide and $\text{CoA-SH}$. An overview of the citric acid cycle is as follows:

Phosphorylation step involves the phosphorylation of the reactant in that step of the citric acid cycle to produce the product.

(c)

Interpretation Introduction

Interpretation: To list the steps, by number in the citric acid cycle that involves condensation.

Concept introduction: Citric acid cycle is the third stage of the biochemical energy production process. The cycle includes the reactions in which the acetyl part of acetyl CoA is oxidized and leads to the formation of carbon dioxide and $\text{CoA-SH}$.

An overview of the citric acid cycle is as follows:

Condensation step involves the condensation of the reactant in that step of the citric acid cycle to produce the product.
