Review 4: Amino Acid Oxidation, Oxidative Phosphorylation, & Photophosphorylation
Oxidative Phosphorylation 1
Multiple Choice
In oxidative phosphorylation, when is ________, it becomes .
A
reduced (gains electrons, typically as a hydride)
B
carboxylated (receives a group)
C
oxidized (loses electrons)
D
phosphorylated (receives a phosphate group)
Verified step by step guidance1
Understand the terms involved: NAD+ and NADH are coenzymes involved in redox reactions during cellular respiration, particularly in oxidative phosphorylation.
Recall the definitions of redox reactions: reduction is the gain of electrons, and oxidation is the loss of electrons.
Identify what happens to NAD+ in oxidative phosphorylation: it gains electrons (and usually a hydride ion, H-) to become NADH.
Match this process to the correct term: since NAD+ gains electrons, it is being reduced to form NADH.
Confirm that other options do not fit: carboxylation involves adding a CO2 group, phosphorylation involves adding a phosphate group, and oxidation would mean losing electrons, which is the opposite of what happens here.
