Blood Glucose Regulation

What is the role of the liver in the regulation of blood glucose?

• It stores excess glucose as glycogen

• It produces insulin and glucagon

• It filters blood to remove excess water

• It absorbs nutrients like glucose from food

Which hormone is released in response to low blood glucose levels?

• insulin

• adrenaline

• glucagon

• ADH

The breakdown of glycogen into glucose molecules when blood sugar levels are low

• Glucagon

• Glycation

• Gluconeogenesis

• Glycogenolysis

Name of the enzyme that insulin activates inside of liver, adipose, and muscle cells

• Glycogen synthase

• Glycogen hydrogenase

• Debranching enzyme

• Lipase

Glucose stored inside of cells in long chains mostly in the Liver

• Glycogen

• Glucagon

• Glycation

• Glycolysis

Write the name of the hormone which is released from alpha cells in the islets of Langerhans?

Glycogen is a hormone that raises blood glucose levels by signaling the liver to release glucose.

• True

• False

Which type of feedback mechanism is involved in the regulation of blood glucose levels?

• Positive feedback

• Negative feedback

• Neutral feedback

• Cyclic feedback

What is the effect of insulin on blood glucose levels?

• Increases blood glucose levels

• Decreases blood glucose levels

• Has no effect on blood glucose levels

• Converts glucose to fat

Glucose moves in and out of cells via GLUT channel proteins

• Facilitated diffusion

• Active transport

• Passive diffusion

• Osmosis
