The Major Function(s)of the TCA Cycle Is(are)

Question

The major function(s)of the TCA cycle is(are)
A)energy production.
B)provision of carbon skeletons for biosynthesis of cell components.
C)electron transport.
D)energy production and provision of carbon skeletons for biosynthesis of cell components.

Accepted Answer

The TCA cycle is responsible for both energy production through the generation of NADH and FADH2, which fuels oxidative phosphorylation in the electron transport chain, as well as providing carbon skeletons for biosynthesis of cell components. Therefore, option D is the best choice as it encompasses both of these functions.
