Question

How does Glucose get into the cell?

Answer 1

Glucose gets into the cells through a process called facilitated diffusion. This is a transport mechanism in which carrier proteins shuttle molecules across the cell membrane without using the cell's energy supplies and so it is called passive transport. The carrier proteins bind to  glucose, which causes them to change shape and translocate the glucose from outside of the cell membrane and into the cell.

(a) glucose is important because it is the primary source of energy for the cell.

(b) Glucose is  6 - carbon monomer of  starch. It is a sugar.

(c) Glucose is broken down to pyruvate through the process of glycolysis.
