Question
Which of the following can be synthesized from all three energy-yielding nutrients? Question 44 options:
a)
glycogen
b)
lactate
c)
oxaloacetate
d)
acetyl CoA
e)
glucose
Solution
The answer is d) Acetyl CoA.
Here's why:
All three macronutrients - carbohydrates, proteins, and fats - can be broken down and converted into Acetyl CoA.
-
Carbohydrates: They are broken down into glucose through the process of glycolysis. Glucose is then further broken down to produce Acetyl CoA.
-
Proteins: They are broken down into amino acids. These amino acids can be converted into various substances, including Acetyl CoA, through a process called deamination.
-
Fats: They are broken down into glycerol and fatty acids. The fatty acids can be converted into Acetyl CoA through a process called beta-oxidation.
Therefore, Acetyl CoA can be synthesized from all three energy-yielding nutrients.
