Biomolecules Question 100
Question: Insulin activates:
Options:
A) Lipolysis
B) Ketogenesis
C) Glycogenolysis
D) Glycolysis
Show Answer
Answer:
Correct Answer: D
Solution:
The correct answer is D) Glycolysis.
Here’s why:
Insulin is a hormone that plays a crucial role in managing glucose levels in the body. It is released by the pancreas in response to high blood glucose levels after a meal. Here’s how it relates to the options given:
A) Lipolysis Lipolysis is the breakdown of fats and other lipids to release fatty acids. Insulin actually inhibits lipolysis, as its primary function is to facilitate glucose uptake into cells for energy. When glucose is available, the body will use that for energy before tapping into fat stores.
B) Ketogenesis Ketogenesis is the production of ketone bodies, which occurs when the body is using fat instead of glucose for energy. Insulin inhibits ketogenesis because, as mentioned above, it promotes the use of glucose for energy.
C) Glycogenolysis Glycogenolysis is the breakdown of glycogen to glucose. Insulin inhibits glycogenolysis because it works to decrease blood glucose levels by promoting its uptake into cells.
D) Glycolysis Glycolysis is the metabolic pathway that converts glucose into pyruvate, releasing energy. Insulin activates glycolysis by promoting the uptake of glucose into cells and its subsequent breakdown for energy.
So, insulin activates glycolysis, making option D the correct answer. It’s important to note that insulin has many functions in the body related to energy storage and usage, and its effects can be quite complex and interconnected. But in the context of this question, glycolysis is the process that insulin activates. Hence, the statement D is true with regard to the action of insulin.
