Explanation:
I'm not quite sure if this was your question, but these are the functions of protiens.
Answer:
(a) can be used to bend epithelial sheets into tubes.
Explanation:
The adherens junctions are cell-cell adhesions localized in places exposed to abrasion or mechanical stress, close to the apical membrane in epithelial cells is one of these locations. Some of their functions are the initiation and stabilization of cell-cell adhesion, <em>they join the actin cytoskeleton to the plasma membrane to form adhesive contacts between cells that contribute to the folding and bending of epithelial sheets,</em> therefore they can mediate adhesion and signaling.

c would be the correct answer to this question
If the liver begins to release glycogen because the pancreas releases glucagon, the amount of <u>the concentration of insulin</u> in the bloodstream must be too low.
<u>Explanation:</u>
Glucagon is considered to be the primary catabolic hormone of the body and is produced by the pancreas.
When insulin in the bloodstream falls low, then the pancreas causes the liver to convert stored glycogen into glucose. Insulin allows glucose to be used by insulin-dependent tissue.
The body releases insulin and glucagon to keep the blood glucose level stable in the body. Under stress, the level of glucagon increases in the body.
