After glucose is degraded in the liver, where is it primarily transported?

• A. To the pancreas for insulin production
• B. To the bloodstream to maintain blood glucose levels
• C. To the muscles for energy
• D. To the kidneys for excretion

Answer: (B)

Verified step by step guidance

1. Understand the role of the liver in glucose metabolism: The liver plays a crucial role in maintaining blood glucose levels by storing glucose as glycogen and releasing it into the bloodstream when needed.
2. Recognize the process of glycogenolysis: When blood glucose levels drop, the liver breaks down glycogen into glucose, a process known as glycogenolysis, to release glucose into the bloodstream.
3. Identify the primary destination of glucose after liver processing: After glucose is degraded in the liver, it is primarily transported to the bloodstream to maintain blood glucose levels.
4. Consider the role of the bloodstream: The bloodstream acts as a transport system, delivering glucose to various tissues and organs that require energy, such as muscles and the brain.
5. Clarify the function of insulin: While insulin is produced by the pancreas and helps regulate blood glucose levels by facilitating the uptake of glucose into cells, the initial transport of glucose from the liver is to the bloodstream.
