What do insulin and glucagon have in common? a) they both provide structural support, but only insulin is a carbohydrate. b) they both store energy, but only glucagon is a carbohydrate. c) they are both hormones that regulate blood-sugar levels. d) they are both hormones that fight disease.

The answer is C- They are both hormones that regulate blood-sugar levels

Insulin increases when we eat a meal and we have all that glucose that needs to be stored otherwise the blood-sugar levels will be to high.

Insulin allows the glucose to enter the cells, and in diabetes this hormone practically doesn't exist, the glucose will accumulate in the blood and cells don't have energy (glucose) to function.

On the other side, glucagon does the opposite. When we are hungry, glucagon is release to avoid glucose levels in the blood to decrease to a risky value. Glucagon makes the liver breakdown accumulated glucose to increase blood-sugar levels.

Insulin and glucagon are both hormones that regulate blood sugar levels in the body.

Further Explanation Blood sugar regulation  Regulation of blood glucose is also known as glucose homeostasis. It involves maintaining the concentration of glucose in blood at a certain constant level. Regulation of blood sugar is undertaken by the endocrine system through the hormones glucagon and insulin. Role of Insulin hormone  Insulin hormone is produced by the pancreas and plays a major role in the regulation of blood sugar. When the concentration of glucose in the blood is too high above the normal range, the pancreas is triggered to produce insulin hormone which in turn enhances the use of glucose by cells and tissues. Insulin also enhances conversion of excess glucose in the liver to glycogen for storage. These action of insulin reduces the blood sugar level to normal range. Role of Glucagon hormone Glucagon is another hormone that also plays a major role in the regulation of blood sugar concentration. When the blood sugar reduces below normal range, glucagon is produced from the pancreas. Glucagon causes less glucose to be absorbed by the body cells and tissues. Additionally, glycogen in the liver cells is converted to glucose. The result is an increase in the blood glucose concentration back to normal range.
