Answer 1

Classify each statement as a description of glycolysis, glycogenesis, glycogenolysis or gluconeogenesis



Answer:

A) Glycolysis:

glucose is the initial reactant

NAD+ is consumed


B) Glycogenesis:

glycogen is the final product

UDP is involved


C) Glycogenolysis:

glycogen is the initial product

this occurs when brain and muscle cells need immediate energy


D) Gluconeogenesis:

glucose is the final product

Glucose-6-phosphate is the final product

Pyruvate is the initial reactant

this occurs in times of insufficient dietary carbohydrate intake


Explanation:

Metabolism of carbohydrates in the body takes place by various metabolic pathways.

In glycolysis, glucose is broken down into pyruvate for energy.

In glycogenesis, formation of glycogen from glucose takes place.

In glycogenolysis, glycogen (n) will break into glucose-1-phosphate and glycogen (n-1).

In gluconeogenesis, formation of glucose from non-carbohydrate sources occurs. Non-carbohydrate sources are pyruvate, lactate, alanine and glutamine.

Two end products of gluconeogenesis are glucose and glucose-6- phosphate.
