    What is homeostasis?

    Maintains stable internal conditions despite external changes.

    What are the components of a feedback system?

    Includes a sensor, control center, and effector.

    How does negative feedback differ from positive feedback?

    Negative feedback reduces change, while positive feedback amplifies it.

    What is the word equation for cellular respiration?

    Glucose + Oxygen → Carbon Dioxide + Water + Energy.

    Why is glucose necessary in the blood?

    It provides energy for cellular respiration.

    What happens if blood glucose levels are too low?

    Cells cannot perform cellular respiration and are energy-starved.

    What causes blood sugar to increase after eating?

    Carbohydrates are broken down into glucose and absorbed.

    What role does the liver play in blood glucose regulation?

    Converts glucose to glycogen for storage or releases glucose into the blood.

    What stimulates glycogenesis?

    Insulin from the pancreas promotes glucose conversion to glycogen.

    What is glucagon's effect on blood sugar levels?

    Increases blood sugar by stimulating glycogenolysis and gluconeogenesis.

    How do adrenal hormones affect blood glucose?

    They elevate glucose levels through glycogenolysis and gluconeogenesis.

    What is the function of insulin?

    Decreases blood sugar by facilitating glucose uptake and storage.

    What is the role of Islets of Langerhans?

    Secretes insulin and glucagon to regulate blood glucose levels.
