Chapter 23, Problem 23.43P

Interpretation Introduction

(a)

Interpretation:

The step involved in the citric acid cycle having a reaction which generates NADH needs to be determined.

Concept Introduction:

The citric acid cycle is an eight steps cycle that consists of enzyme-catalyzed reactions that occur in mitochondria. The citric acid cycle starts with the addition of 2 carbon acetyl CoA molecules to four carbon substrates. Acetyl CoA is regenerated at the end of the cycle.

Interpretation Introduction

(b)

Interpretation:

The step involved in the citric acid cycle in which CO₂ is removed needs to be determined.

Concept Introduction:

The citric acid cycle is an eight steps cycle that consists of enzyme-catalyzed reactions that occur in mitochondria. The citric acid cycle starts with the addition of 2 carbon acetyl CoA molecules to four carbon substrates. Acetyl CoA is regenerated at the end of the cycle.

Interpretation Introduction

(c)

Interpretation:

The step involved in the citric acid cycle having the reactions which utilize FAD needs to be determined.

Concept Introduction:

The citric acid cycle is an eight steps cycle that consists of enzyme-catalyzed reactions that occur in mitochondria. The citric acid cycle starts with the addition of 2 carbon acetyl CoA molecules to four carbon substrates. Acetyl CoA is regenerated at the end of the cycle.

Interpretation Introduction

(d)

Interpretation:

The step involved in the citric acid cycle having the reaction which forms a new carbon-carbon single bond should be given.

Concept Introduction:

The citric acid cycle is an eight steps cycle that consists of enzyme-catalyzed reactions that occur in mitochondria. The citric acid cycle starts with the addition of 2 carbon acetyl CoA molecules to four carbon substrates. Acetyl CoA is regenerated at the end of the cycle.
