What is an Insulin? (SATA)
A
a hormone that your pancreas makes to allow cells to use glucose
B
most important simple sugar in human metabolism
C
moves glucose from blood into the cells for energy and storage
D
universal cellular fuel
Explanation: 

Detailed explanation-1: -Insulin is a hormone that moves glucose from your blood into the cells for energy and storage. People with diabetes have higher-than-normal levels of glucose in their blood. Either they don’t have enough insulin to move it through or their cells don’t respond to insulin as well as they should.

Detailed explanation-2: -Like a key fits into a lock, insulin binds to receptors on the cell’s surface, causing GLUT4 molecules to come to the cell’s surface. As their name implies, glucose transporter proteins act as vehicles to ferry glucose inside the cell.

Detailed explanation-3: -Insulin is a peptide hormone secreted by the cells of the pancreatic islets of Langerhans and maintains normal blood glucose levels by facilitating cellular glucose uptake, regulating carbohydrate, lipid and protein metabolism and promoting cell division and growth through its mitogenic effects.

Detailed explanation-4: -Insulin stimulates adipose tissue uptake of fatty acids, which are later converted into triglycerides and used as long-term energy stores.

Detailed explanation-5: -Insulin is needed to move blood sugar (glucose) into cells. Inside the cells, glucose is stored and later used for energy.
