Pathways of Glucose Metabolism

Question 1

Explain Glycolysis and its effect on glucose level

Answer 1

Metabolism of glucose to energy. It decreases blood glucose level

Question 2

Explain Gluconeogenesis and its effect on glucose level

Answer 2

Formation of glucose from non-carbohydrate source (protein, amino acids/ lipids). This increases blood glucose level

Question 3

Explain Glycogenolysis and its effect on glucose level

Answer 3

Glycogenolysis is the breakdown of glycogen (stored form of glucose). When glycogen is broken-down, it forms more glucose which increases glucose level in blood.

Question 4

Explain Glycogenesis and its effect on glucose level

Answer 4

Formation of glycogen. It is the storage of excess glucose by converting glucose to glycogen, which decreases the level of glucose in the blood.

Question 5

Explain Lipogenesis and its effect on glucose level

Answer 5

Conversion of carbohydrate to fatty acids . This decreases blood glucose level.

Question 6

Explain Lipolysis and its effect on glucose level

Answer 6

Decomposition or breakdown of fats (occurs if glucose is insufficient/ absent). Fats will be utilized instead of glucose to form energy.

Question 7

Why does ketosis result in comatose?
