NAD and redox reaction

Question 1

1.
electron are carried between one part of the

Answer 1

energy-harvesting process and another by electron carriers, primarily NAD

Question 2

2.
in its “empty” (oxidized) state, this molecule exists as

Answer 2

NAD+

Question 3

3.
Through a redox reaction NAD+ picks up 1 Hydrogen atom and another single electron (actually 2 electrons) from a nurtrient, thus becoming

Answer 3

NADH (reduced)

Question 4

4. ultimately NADH drop off its energetic electrons (and a proton) in a later stage of the energy-harvesting process to return the

Answer 4

NAD+ state
