B.) pyruvic acid
C.) ADP
D.) ATP

Answer 4

ohhh...out of these it should be NAD+

Answer 5

I THINK

Answer 6

A number of molecules can act as electron carriers in biological systems. In cellular respiration, there are two important electron carriers, nicotinamide adenine dinucleotide (abbreviated as NAD+ in its oxidized form) and flavin adenine dinucleotide (abbreviated as FAD in its oxidized form). The NAD+ molecule is used to accept electrons (becomes reduced) in several chemical reactions in glycolysis and the Krebs cycle. NAD+ accepts a hydrogen ion (H+) and two electrons (2e-), as it becomes reduced to NADH + H+. The NADH moves to the electron transport chain and donates a pair of electrons (becomes oxidized) to the first compound in the chain. The oxidation of NADH to NAD+ results in the liberation of 53 kcal/mole (under standard conditions).
