Step 1: Understand the role of hormones in blood glucose regulation. Blood glucose levels are tightly controlled by hormones to maintain homeostasis.
Step 2: Identify the hormone that lowers blood glucose levels. Insulin is known to decrease blood glucose by promoting cellular uptake of glucose.
Step 3: Identify the hormone that increases blood glucose levels. Glucagon acts to raise blood glucose by stimulating glycogen breakdown and glucose release from the liver.
Step 4: Recognize that Antidiuretic hormone (ADH) primarily regulates water balance and does not directly affect blood glucose levels.
Step 5: Understand that Calcitonin is involved in calcium homeostasis and does not influence blood glucose levels.
