It is transported into cells. b) It can remain, circulating in the blood indefinitely. c) It can be stored as glycogen until it is needed for energy. d) It is used as fuel for cellular activities.

Answer 1

Answer:

B) It can remain, circulating in the blood indefinitely, this is not a fate of glucose circulating in the blood of a healthy individual.

Explanation:

Glucose is produced by breaking down carbohydrates, principally in the small intestine, when we eat a meal containing carbohydrates.This glucose enters the bloodstream.When glucose is in excess, the body stores it away in the form of glycogen in a process stimulated by insulin. Glycogen is a large highly branched structure, made from lots of glucose molecules linked together.Glycogen is mainly stored in the liver and muscles, therefore, excess glucose is removed from the blood stream and stored.

Insulin signals to the cell to translocate Glut 4 to the cell membrane, so that large amounts of glucose can be taken into the cell, via the Glut 4 transporters and converted into glycogen and used as a fuel for cellular activities. Furthermore with the help of insulin, converted into fatty acids, circulated to other parts of the body and stored as fat in adipose tissue.
