(a)
Interpretation:
The cell in which glycolysis pathway occurs has to be identified.
Concept Introduction:
Glycolysis process: This process breakdown of glucose into pyruvic acid, this whole process generates two ATP’s.
This process serves as the foundation for both aerobic and anaerobic
(b)
Interpretation:
The cell in which Gluconeogenesis pathway occurs has to be identified.
Concept Introduction:
Gluconeogenesis the synthesis of glucose from non-carbohydrate sources runs when available glucose from the diet and stored glycogen has been used up.
(c)
Interpretation:
The cell in which Glycogenesis pathway occurs has to be identified.
Concept Introduction:
Glycogenesis is the process of glycogen synthesis, in which glucose molecules are added to chains of glycogen for storage.
Metabolism: This process refers to biochemical process that occur any living organism including humans to maintain life.
(d)
Interpretation:
The cell in which glycogenolysis pathway occurs has to be identified.
Concept Introduction:
Metabolism: This process refers to biochemical process that occur any living organism including humans to maintain life.
Glycogenolysis: The biochemical pathway for breakdown of glycogen to free glucose.
