Question

The hormone _____ stimulates the storage of triglycerides during times of energy excess, such as after a meal, by causing adipocytes, and to a lesser extent skeletal muscle, to take up glucose and fatty acids from the bloo

Answer 1

Answer:

Insulin

Explanation:

Insulin signalling promotes lipid storage in adipocytes by both stimulating triacylglycerol synthesis and inhibiting its breakdown.

Insulin’s inhibition of lipolysis aids storage of lipids and also decreases circulating fatty acid level.

Answer 2

Answer:

Insulin.

Explanation:

When we eat carbohydrate foods, there is an increased level of glucose in the blood. The body works to metabolize this glucose into energy for its use. Excess glucose is converted to glycogen for storage in the muscles and liver. When these glycogen storages are filled up, glucose is converted to fatty acids for storage as triglycerides in the process of lipogenesis.

Lipogenesis is activated by insulin which is released from the pancreas when blood glucose increases. Lipogenesis helps store energy for the long term when there is excess of it.

The process of lipogenesis is carried out through the carboxylation of acetyi-coA to malonyl-coA by acetyi-coA carboxylase. This process occurs in the adipose tissues, the liver and the skeletal muscles.Another pathway of lipogenesis is the pyruvate dehydrogenase pathway, activated by insulin.
