Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the function of NADP+?
A
It absorbs light
B
It is an electron carrier
C
It is a light-reflecting pigment
D
It acts as long-term energy storage
Explanation: 

Detailed explanation-1: -NADP is an electron carrier. It stands for Nicotinamide Adenine Dinucleotide Phosphate. NADP works with numerous enzymes to supply energy to the numerous processes in a cell. It accepts electrons and gets reduced to NADPH.

Detailed explanation-2: -A major role of NADP is its role as co-enzyme in cellular electron transfer reactions. Moreover, the cell spends a significant amount of energy to keep NADP in its reduced form, thereby maintaining a readily available pool of electrons to reduce oxidized compounds.

Detailed explanation-3: -Because NADH and NADPH are electron carriers, it is important to recognise both reduced and oxidised forms.

Detailed explanation-4: -What happens during the process of photosynthesis? NADP+ is an empty electron carrier molecule that bonds with electrons and protons from water split during the light reactions. The loaded electron carriers, NADPH, deliver these electrons and protons to the enzymes that combine them with C and O to build sugar.

Detailed explanation-5: -NADH: High energy electron carrier used to transport electrons generated in Glycolysis and Krebs Cycle to the Electron Transport Chain. FADH2: High energy electron carrier used to transport electrons generated in Glycolysis and Krebs Cycle to the Electron Transport Chain.
