Answer: Uptake and utilization of glucose by cells, and its conversion to glycogen in the liver.
- A Breakdown of liver glycogen into glucose, releasing it into the blood in general clinical practice
- B Conversion of fats into glucose within adipose tissue as frequently documented in most reference accounts
- C Excretion of excess glucose by the kidneys under normal conditions as generally observed
- D Uptake and utilization of glucose by cells, and its conversion to glycogen in the liver
Correct answer: D. Uptake and utilization of glucose by cells, and its conversion to glycogen in the liver
Explanation: Insulin, secreted by beta cells of the pancreas, promotes cellular glucose uptake and glycogenesis in the liver, lowering blood glucose levels.
The hypothalamus releases hormones that direct the pituitary, which releases its own trophic hormone to a target gland; that gland's hormone output then feeds back (dashed lines) to suppress both the pituitary and hypothalamus once levels are sufficient - a self-correcting loop running the entire endocrine system.
