Question

A patient arrives at the physician’s office for blood work after an overnight fast. Which of the following apply?

A. The patient is in the absorptive state.

B. The patient’s liver is releasing glucose via glycogenolysis.

C. His fat stores are mobilized as an energy source and for conversion to glucose.

D. His muscles are in an anabolic state.

E. Two of the above apply.

Why are lipids such efficient energy storage molecules as compared to carbohydrates?

A. They are hydrophobic.

B. They contain 4 kcal per gram of fat.

C. They are less compact than carbohydrates.

D. They hold a lot of water.

E. None of the above

The answer for the first one will be

His fat stores are mobilized as an energy source and for conversion to glucose.

As we fast first our glycogen is used up from muscles and liver by glycogenolysis.

Muscles can't be in the anabolic stage as it means synthesis.

So, the person is fasting overnight, until now the person's glucose reserve is extinguished.

So, the person is left with only fat to be metabolized.

So, the answer will be C.

They are hydrophobic is correct but not an answer to this question

The answer for the second one will be They are less compact than carbohydrates.

They don't hold as much water as carbohydrates.
