QUESTION
In the Process of Gluconeogenesis?
OPTIONS
(A) Glucose is formed from carbohydrate substrate
(B) Glucose is formed from other than carbohydrate substrate
(C) Glucose is formed from minerals
(D) Glucose is formed from minerals and vitamins
ANSWER
(B) Glucose is formed from other than carbohydrate substrate
EXPLANATION
Glucose is formed from other than carbohydrate substrate is the correct option because gluconeogenesis is the synthesis of glucose from non-carbohydrate precursors such as lactate, glycerol and glucogenic amino acids. It is not simply glucose formation from carbohydrate, and minerals or vitamins alone are not converted into glucose as the defining substrates of gluconeogenesis.
