Which of the following is NOT a function of the TCA cycle:

a. Provide carbon skeletons for biosysthesis
b. Provide electron to the electron transport chain in the form of NADH
c. make ATP
d. Break down pyruvate.

I know both a and c are the function of TCA cycle. I'm not sure about b and d. My answer would be b. Can anyone help me if my answer is correct

Here's a GOOGLE Search on the Cycle. sorry, but this is not my area!
