RPAScience A Level Blood Glucose Regulation

What causes blood glucose levels to rise?

• eating

• vigorous exercise

• sleeping

• going to the toilet

What causes blood glucose levels to fall?

• eating

• vigorous exercise

• sleeping

• going to the toilet

What do cells need glucose for?

• photosynthesis

• respiration

• protein synthesis

• combustion

What does insulin promote in the liver?

• hydrolysis of glycogen

• hydrolysis of glucagon

• release of glucose

• production of glycogen

What does glucagon promote in the liver?

• hydrolysis of glycogen

• hydrolysis of glucose

• production of glycogen

• release of insulin

The function of adrenaline in the regulation of blood glucose is (choose 2):

• hormone which activates enzyme to convert to cAMP

• cAMP starts cascade of reactions which turn glycogen to glucose (glycogenolysis)

• cAMP starts cascade of reactions which triggers glucoaneogenisis

• hormone that passes through the cell membrane to trigger glycogenolysis

Glucagon causes the liver to start:

• glycogenolysis

• glucagoneogenisis

• glycogenisis

• production of insulin

Insunlin causes the liver to start:

• glycogenolysis

• glucagoneogenisis

• glycogenisis

• production of insulin

The production of glucose from fats triggered by glucagon is called

• glycogenolysis

• glucagoneogenisis

• glycogenisis

• production of insulin

Which does not reduce blood sugar

• absorb more glucose

• increase respiration

• synthesise glycogen

• respire lipids and proteins
