Insulin plays a part in homeostasis. It affects muscle and liver cells to bring about a decrease in blood glucose concentration, particularly after a meal.
Describe the effects of insulin on muscle cells.
causes glucose uptake/increases permeability to glucose ;
adds transport proteins to cell (surface) membrane ;
A in sarcolemma A GLUT(4), proteins / channels / carriers more glucose respired/increase in respiration rate ;
