Question
Chapter 22, Problem 22.63AP
Interpretation Introduction
Interpretation:
The two consecutive conversions of pyruvate in the process of anabolism of glucose has to be filled in the given the statement.
Concept Introduction:
Catabolism: This pathway release energy by breaking down complex molecules into simpler compounds.
Anabolic pathway: It is consumed energy to build complex molecules from simpler ones.
For example: The synthesis of protein from amino acids is an example of anabolism.
