AP PSYCHOLOGY

Detailed explanation-1: -Glucagon increases blood sugar levels, whereas insulin decreases blood sugar levels.

Detailed explanation-2: -In this system, hormones are the most important regulators of glucose homeostasis. Insulin is the only hormone that lowers plasma glucose. When plasma glucose falls below 70 mg/dl, insulin secretion is suppressed to prevent any additional decrease in plasma glucose.

Detailed explanation-3: -While glucagon keeps blood glucose from dropping too low, insulin is produced to keep blood glucose from rising too high. The two hormones counterbalance each other to stabilize blood glucose.
