Q.1
How does insulin reduce blood glucose levels?
  • it breaks down glucose
  • promotes the release of glucose from cells through a transporter
  • promotes the uptake of glucose into cells through a transporter
  • it prevents the intestine from releasing glucose into the blood
Q.2
Excess glucose in the bloodstream is converted to which other substance when stored in the liver and muscle cells?
  • glycogen
  • glucagon
  • glycerin
  • glycerol
Q.3
What happens to the amount of insulin released if the blood glucose levels get low?
  • lots more is produced
  • nothing - low blood glucose has no effect on insulin levels
  • less / no insulin is produced
Q.4
What causes blood glucose levels to rise?
  • eating
  • vigorous exercise
  • sleeping
  • going to the toilet
Q.5
What causes blood glucose levels to fall?
  • eating
  • vigorous exercise
  • sleeping
  • going to the toilet
Q.6
What do cells need glucose for?
  • photosynthesis
  • respiration
  • protein synthesis
  • combustion
Q.7
Which of the following is a hormone used to control glucose concentrations in the blood?
  • insulin
  • glycogen
  • pancreas
  • adrenaline
Q.8
Insulin causes which organ to remove glucose from the blood?

  • pancreas
  • brain
  • kidneys
