Which of the following functional groups acts as an electron carrier in biochemical reactions?
A
Nicotinamide adenine dinucleotide (NAD+)
B
Phosphate group
C
Sulfhydryl group
D
Hydroxyl group
Verified step by step guidance1
Identify the role of each functional group in biochemical reactions. Consider what it means to act as an electron carrier.
Understand that an electron carrier is a molecule that transports electrons during cellular respiration. It plays a crucial role in energy production.
Examine the structure and function of Nicotinamide adenine dinucleotide (NAD+). Recognize that NAD+ is a coenzyme found in all living cells and is a key electron carrier.
Compare the roles of the phosphate group, sulfhydryl group, and hydroxyl group. Note that these groups do not primarily function as electron carriers.
Conclude that Nicotinamide adenine dinucleotide (NAD+) is the functional group that acts as an electron carrier in biochemical reactions, facilitating the transfer of electrons in metabolic pathways.
