Energy and Enzymes Energy Energy refers to the capacity to move or change matter. Electron Carriers in Cellular Respiration NAD (Nicotinamide Adenine Dinucleotide) NAD + functions in cellular respiration by carrying two electrons from one reaction site to another. NAD + + 2H NADH + H + It oxidizes its substrate by removing two hydrogen atoms. One of the hydrogen atoms bonds to the NAD + . The electron from the other hydrogen atom remains with the NADH molecule but the proton ( H + ) is released. NAD + becomes reduced to NADH. NADH can transfer two electrons (one of them is a hydrogen atom) to another molecule. FAD (Flavin Adenine Dinucleotide) FAD is reduced to FADH

Unformatted text preview: 2 . It can transfer two electrons to another molecule. FAD + 2H FADH 2 NADH and FADH 2 bring electrons to the electron transport system in cellular respiration. Electron Carrier in Photosynthesis NADP + (Nicotinamide Adenine Dinucleotide Phosphate) NADP + + 2H NADPH + H + NADP + is similar to NAD + in that it can carry two electrons. One of the electrons is contained within a hydrogen atom, the other is removed from a hydrogen atom and the remaining proton is released. . Electrons carried by NADPH in photosynthesis are ultimately used to reduce CO 2 to carbohydrate ....
