In the context of organic chemistry reactions, how does NADP+ become NADPH?
A
By gaining an electron and a proton
B
By gaining a phosphate group
C
By undergoing a decarboxylation reaction
D
By losing an electron
Verified step by step guidance1
Understand that NADP+ (Nicotinamide adenine dinucleotide phosphate) is a coenzyme involved in redox reactions, acting as an electron carrier.
Recognize that the conversion of NADP+ to NADPH involves a reduction process, where NADP+ gains electrons.
Identify that in biological systems, reduction often involves the gain of a hydride ion (H⁻), which consists of an electron and a proton.
Note that the addition of a hydride ion to NADP+ results in the formation of NADPH, which is the reduced form of the coenzyme.
Conclude that the correct mechanism for NADP+ becoming NADPH is by gaining an electron and a proton, which corresponds to the reduction process.
