Question

If you’re on a fat-free diet, is there a role for the liver in digestion?

A. No role, bile secreted from the liver is only needed for fat digestion

B. The liver will convert amino acids into glucose & fat

C. Bile contains enzymes that process some carbohydrates

D. None of the above

__________________

I know there is no such thing as a “fat-free” diet, but this is a hypothetical situation.

For A, I’m unsure if there is another role instead of this.

For B, this is true but is it considered a metabolic function and not a means of digestion (mechanical & chemical breakdown of food)?

For C, I cannot find evidence to support this.

Can you please explains what might be the answer and your reasoning for it? Thank you

Explanation / Answer

answer is B. Yes, the liver will convert amino acids into glucose and fat

First of all, there is no such thing as a fat-free diet - or rather if you were to eat one, you would die: fats are an integral part of all terrestrial life, so all food that you eat will contain some.

'Digestion' just refers to the process of breaking food down into its usable components. Gluconeogenesis - what you're referring to, converting other molecules into glucose - happens downstream of digestion, and would be considered a metabolic activity.

the liver will still regulate blood-glucose levels. Even without fat in your diet, you'll still have fluctuations in blood glucose level.

I would consider amino acid breakdown part of digestion, but not gluconeogenesis.

liver in digestion serves in bile production which is realeased by the gallbladder. bile being key in emulsification of fats. so no fats no need for bile.
