Concept explainers
(a)
Interpretation:
Steps in glycolysis that consume ATP have to be given.
Concept Introduction:
- 1. Catabolism
- 2. Anabolism
Catabolism: The catabolic pathway involves oxidation reactions and produces energy and it converts complex molecules into simple ones
Anabolism: The anabolic pathway involves a series of sequential reactions which converts simple molecules into complex molecules.
Glycolysis: It is pathway which describes conversion of one molecule of glucose into two molecules of pyruvate. The series involves 10 reactions.
(b)
Interpretation:
Steps in glycolysis that produce ATP have to be given.
Concept Introduction:
Metabolism: The process by which living organisms synthesize energy they required is known as metabolism. Mainly there are two pathways
- 1. Catabolism
- 2. Anabolism
Catabolism: The catabolic pathway involves oxidation reactions and produces energy and it converts complex molecules into simple ones
Anabolism: The anabolic pathway involves a series of sequential reactions which converts simple molecules into complex molecules.
Glycolysis: It is pathway which describes conversion of one molecule of glucose into two molecules of pyruvate. The series involves 10 reactions.
