What is the primary role of insulin in blood glucose regulation?
To stimulate fat storage
To signal cells to take up glucose
To promote glycogen breakdown
To increase blood glucose levels
What happens to blood glucose levels after insulin is released?
They fluctuate wildly
They decrease as glucose is taken up by cells
They remain unchanged
They increase significantly
What is the function of glucagon in glucose regulation?
To enhance insulin sensitivity
To stimulate glycogenolysis in the liver
To promote glucose uptake by cells
To lower blood glucose levels
How does exercise affect glucose uptake in muscles?
It has no effect on glucose uptake
It promotes insulin-independent glucose uptake
It stimulates insulin release
It decreases glucose uptake
What is the primary energy source for muscle contraction during exercise?
Glucose
Amino acids
Lactate
Fatty acids
What should an elite marathon runner do to prepare for a race?
Increase protein intake
Reduce fluid intake
Avoid carbohydrates
Consume a carbohydrate-rich diet
What is the role of GLUT4 transporters?
To transport glucose into cells
To release glucose into the bloodstream
To break down glycogen
To synthesize triglycerides
What effect does high-intensity exercise have on glucose uptake?
It decreases glucose uptake
It has no effect on glucose uptake
It induces greater glucose uptake
It only affects fat metabolism
What is the consequence of prolonged or intense exercise on glycogen?
Decreased reliance on blood glucose
No effect on glycogen levels
Glycogen depletion
Increased glycogen storage
How does regular exercise impact insulin sensitivity?
It decreases insulin sensitivity
It has no effect
It only affects glucose tolerance
It enhances insulin sensitivity
What should a diabetic athlete do regarding insulin during a race?
Ignore insulin needs
Adjust insulin dosages based on energy expenditure
Increase insulin intake
Stop using insulin completely
What is the primary function of glucagon during fasting?
To lower blood glucose levels
To stimulate glycogen breakdown
To promote glucose uptake
To enhance muscle contraction
What is the effect of muscle contractions during exercise on glucose?
They inhibit glucose uptake
They stimulate glucose release
They promote glucose uptake via insulin-independent pathways
They have no effect on glucose levels
What is the role of adrenaline in glucose regulation during exercise?
To enhance glucose uptake
To promote fat storage
To stimulate glycogen breakdown
To lower blood glucose levels
