Answer:
A. The complementary shapes of an enzyme and a substrate
Explanation:
The Lock-and-Key model was made to show how an enzyme's active zone fits a substrate and how they bond together. It correlates just like a lock and a key; you have to have the correct-shaped key in order to open a lock. Same process of thought with the enzymes; you must have the same shape for both in order to bind together,

The increase in the glucagon secreted by the alpha cells of "islets of langerhans" in he pancreas would lead to a rise in the blood sugar level.
The decrease in the secretion of insulin from the beta cells of "islets of langerhans" in the pancreas would also lead to higher blood sugar level
