The principal electron carriers of cellular respiration are derivatives of nucleotides and come from which group of vitamins?
AThe vitamin K group
BThe vitamin A group
CThe vitamin C group
DThe vitamin B group
Answer & Solution
Correct answer: D. The vitamin B group
1. Electron carriers are small compounds that bind and shuttle high-energy electrons between compounds in pathways.
2. The principal carriers are derived from the B vitamin group and are derivatives of nucleotides.
3. Nicotinamide adenine dinucleotide comes from niacin, one of the B vitamins.
4. No carrier in this set is built from vitamin A, C or K.
