Which of the following is an effect of glucagon?

• Buildup of glycogen in skeletal muscle and liver cells, which cannot be used for energy production

• Decreased production of glucose in the liver

• Breakdown of triglycerides in adipose tissue, which can be released as fatty acids in the bloodstream

When glucose levels in the blood rise, your brain sends a signal to your pancreas. The pancreas releases insulin, which opens channels in cell membranes to allow glucose to enter the cell, lowering blood sugar levels. This is an example of a:

• Positive Feedback Loop

• Negative Feedback Loop

What hormone is produced in the pancreas that raises blood sugar?

• Insulin

• Glucagon

• Ketones

• Glucose

Homeostasis

• allows for a wildly fluctuating internal environment

• is impossible in vertebrates
