Term
Insulin
Definition
peptide hormone that plays an important role in allowing fat tissue and skeletal muscles to absorb glucose from the bloodstream
Term
GLUT 4
Definition
type of transporter protein for glucose in fat cells and skeletal muscle cells
Term
facilitated diffusion
Definition
movement of a molecule through a transporter protein from an area of high concentration to and area of low concentration
Term
vesicle
Definition
intracellular storage structure for GLUT4 transporter proteins
Term
GLUT4-containing vesicles being transported to the cell membrane
Definition
effect of phosphorylation cascade triggered by conformational change of insulin receptor
Term
Type 1 diabetes
Definition
caused by a failure to produce insulin in the pancreas
Term
Type 2 diabetes
Definition
caused by loss of insulin receptor function. This type of diabetes is usually associated with obesity.
Term
Type 1 diabetes
Definition
treated with regular injections of insulin throughout the day
Term
Type 2 diabetes
Definition
may be treated with medications to lower blood glucose levels along with lifestyle changes
Term
exercise
Definition
lifestyle factor that triggers recruitment of GLUT4 so can improve uptake of glucose
Term
