Verified step by step guidance1
Step 1: Understand the role of hormones in hunger regulation. Hormones are chemical messengers that help regulate appetite and energy balance in the body.
Step 2: Learn about ghrelin, which is often referred to as the 'hunger hormone.' Ghrelin is primarily released by the stomach and signals the brain to stimulate appetite.
Step 3: Compare ghrelin with other hormones listed in the options. For example, cholecystokinin (CCK) is involved in satiety (feeling full), insulin regulates blood sugar levels, and leptin signals the brain to reduce appetite when fat stores are sufficient.
Step 4: Identify the hormone that matches the description of being the primary hunger hormone released by the stomach. Based on the information, ghrelin fits this role.
Step 5: Conclude that ghrelin is the correct answer by understanding its function and distinguishing it from the roles of CCK, insulin, and leptin.
