Glucose Insulin Concentration Cell Enzymes Decrease Blood β

Front How does insulin work?
Back
- decrease in blood glucose concentration detected by β cell receptors
- β cells secrete insulin

- insulin attaches to insulin receptors on surface of target cells
- receptor activates enzymes
- enzymes activate protein carrier vesicle causing it to fuse with membrane
- increase in the number of glucose carrier proteins in cell membrane
- increase in permeability to glucose
- more facilitated diffusion of glucose into the cell
- enzymes activated to convert glucose into glycogen by glycogenesis, maintaing larger concentration gradient for facilitated diffusion of glucose
- decrease in blood glucose concentration
