Which molecule is waiting to pickup electrons?
|
|
ADP
|
|
|
ATP
|
|
|
NADPH
|
|
|
NADP+
|
Explanation:
Detailed explanation-1: -The lower energy form, NADP+, picks up a high energy electron and a proton and is converted to NADPH.
Detailed explanation-2: -NADP+ is a coenzyme that functions as a universal electron carrier, accepting electrons and hydrogen atoms to form NADPH, or nicotinamide adenine dinucleotide phosphate.
Detailed explanation-3: -Light energy is harvested and used to power the transfer of electrons among a series of electron donors and acceptors. The final electron acceptor is NADP+, which is reduced to NADPH. NADPH generated from light reactions is used in sugar synthesis in dark reactions.
Detailed explanation-4: -NADPH carries high-energy electrons to the electron transport chain in photosynthesis.
