Answer: (E)

Verified step by step guidance

1. Understand the role of insulin: Insulin is a hormone produced by the pancreas that helps regulate blood sugar levels. When blood sugar levels rise, insulin is released to help cells absorb glucose from the bloodstream.
2. Identify the trigger for insulin release: Eating a cookie or candy bar increases blood sugar levels because these foods contain carbohydrates that are broken down into glucose.
3. Recognize the body's response to high blood sugar: The pancreas detects the increase in blood sugar and releases insulin into the bloodstream.
4. Differentiate insulin from other hormones: Secretin, calcium, glycogen, and glucagon have different roles in the body. Secretin is involved in digestion, calcium is a mineral, glycogen is a stored form of glucose, and glucagon raises blood sugar levels.
5. Conclude that insulin is the hormone responsible for lowering blood sugar levels after consuming sugary foods, as it facilitates the uptake of glucose by cells.
