Question

First, let’s restate the question to clarify what is being asked: Excess and unused fatty acids carried by albumin are taken up by ___.

Option 1: liver, and reassembled into triglycerides. This option aligns with physiological knowledge that fatty acids bound to albumin can be delivered to the liver, where they are re-esterified and stored as triglycerides or used for lipid synthesis. The liver is a central hub for lipid metabolism, making this option plausible and correct.

Option 2: brain, and made into glucose. The brain primarily relies on glucose and ketone bodies; fatty acids themselves are not transported to the brain in a form that is converted into glucose within the brain. The conversion of fatty acids into glucose does not occur in the brain via fatty acid transport, so this is inaccurate.

Option 3: muscle, and made into protein. While fatty acids can be used by muscle for energy and can influence protein turnover, the specific statement that fatty acids carried by albumin are taken up by muscle and converted into protein is not the typical major fate of these fatty acids. Thus this option misstates the primary metabolic destination and product comparison.

In sum, the physiological pathway most consistent with fatty acids carried by albumin is transport to the liver for reassembly into triglycerides, rather than delivery to the brain for glucose, or to muscle for protein synthesis. The liver’s role in lipid metabolism supports Option 1 as the accurate choice.
