Chapter 19, Problem 6RE

Interpretation Introduction

Interpretation:

The steps through which pyruvate from glycolysis is converted into pyruvate dehydrogenase complex are to be explained.

Concept introduction:

 The breakdown of a glucose molecule to produce ATP, NADH, and pyruvate molecules is called glycolysis.

 The pyruvate is the initial reacting substrate for the citric acid cycle that goes through several reactions in the presence of the enzyme pyruvate dehydrogenase complex to give acetyl-CoA.

 The pyruvate dehydrogenase complex is a set of five enzymes, namely, pyruvate dehydrogenase, hydro lipoyl transacetylase, dihydrolipoyl dehydrogenase, pyruvate dehydrogenase kinase, and pyruvate dehydrogenase phosphatase.
