Insulin and Glucagon: Blood Sugar Control

What is the primary function of insulin in the body?

• The primary function of insulin is to lower blood glucose levels by promoting glucose uptake into cells.

• Insulin regulates blood pressure by constricting blood vessels.

• Insulin increases blood glucose levels by inhibiting glucose uptake.

• Insulin is primarily responsible for fat digestion in the stomach.

How does glucagon affect blood sugar levels?

• Glucagon increases blood sugar levels.

• Glucagon stabilizes blood sugar levels.

• Glucagon has no effect on blood sugar levels.

• Glucagon decreases blood sugar levels.

Which organ produces insulin?

• Liver

• Kidneys

• Pancreas

• Spleen

What triggers the release of insulin?

• Low blood pressure

• High protein intake

• Decreased physical activity

• Elevated blood glucose levels.

What is the effect of insulin on liver cells?

• Insulin stimulates glycogen synthesis and inhibits gluconeogenesis in liver cells.

• Insulin decreases glycogen synthesis and promotes gluconeogenesis in liver cells.

• Insulin stimulates fat breakdown and inhibits glycogen synthesis in liver cells.

• Insulin has no effect on glycogen metabolism in liver cells.

How does glucagon help raise blood sugar levels?

• Glucagon has no effect on blood sugar levels.

• Glucagon converts glucose to glycogen in muscle tissue.

• Glucagon raises blood sugar levels by stimulating the liver to convert glycogen to glucose and promoting gluconeogenesis.

• Glucagon lowers blood sugar levels by inhibiting liver function.

What condition is characterized by high blood sugar levels due to insulin deficiency?

• Diabetes mellitus (type 1)

• Type 2 diabetes

• Insulinoma

• Hypoglycemia

Which hormone is released when blood sugar levels drop?

• Insulin

• Cortisol

• Adrenaline

• Glucagon

What role does the pancreas play in blood sugar regulation?

• The pancreas absorbs glucose from the bloodstream.

• The pancreas secretes adrenaline to lower blood sugar.

• The pancreas produces bile to regulate blood sugar.

• The pancreas regulates blood sugar by producing insulin and glucagon.

How do insulin and glucagon work together?

• Both insulin and glucagon lower blood sugar levels.

• Insulin and glucagon have no effect on blood sugar levels.

• Insulin lowers blood sugar levels, while glucagon raises them.

• Insulin raises blood sugar levels, while glucagon lowers them.
