Explain the role of insulin
and muscle contraction on glucose uptake during exercise.
Insulin
and muscle contraction stimulate glucose uptake from the blood into skeletal
muscles.
Insulin
is secreted by beta cells
During
anaerobic glycolysis, to maintain energy supply the muscles increase glucose
intake
*Exercise
lower the amount of insulin in the blood
-- Not
a problem because muscle contractions stimulate the translocation of glucose
transported from the inner cell storage pool to the cell membrane but in a
different ways to insulin.
