Insulin is the key hormone responsible for lowering blood sugar levels. It facilitates glucose uptake by cells, especially muscle and liver cells, and prevents excessive glucose production by the liver.
Step 1: Understanding the role of insulin in blood sugar regulation.
Insulin is a hormone secreted by the pancreas that helps regulate blood sugar levels by promoting the uptake of glucose into cells and reducing blood glucose concentration.
Step 2: Explanation of incorrect options.
- Estrogen and Progesterone are hormones primarily involved in reproductive functions.
- Relaxin is associated with pregnancy and childbirth, not blood sugar regulation.
