Final answer:
The effect a food has on a person's blood sugar levels is known as glycemic response. Insulin helps to lower blood glucose levels by promoting the uptake of glucose by cells.
Step-by-step explanation:
The effect a food has on a person's blood sugar levels is known as glycemic response. When we eat food, it can cause a rise in blood glucose levels, and the body responds by releasing the hormone insulin. Insulin helps to lower blood glucose levels by promoting the uptake of glucose by cells, where it can be used for energy or stored as glycogen. In this way, insulin plays a crucial role in maintaining blood sugar homeostasis.
