How many electrons does NADP+ carry?
When NADP+ and a suitable enzyme are present, two ferredoxin molecules, carrying one electron each, transfer two electrons to NADP+, which picks up a proton (i.e., a hydrogen ion) and becomes NADPH.
What does NADPH carry electrons to?
The chloroplasts present in the plants also use NADPH as a part of the pathway to synthesize sugars from the sunlight and also from the carbon dioxide. Likewise, in other reactions, NADPH carries electrons and protons into the new carbon-carbon bonds, creating sugar molecules.
Are NADPH electron carriers?

Nadp plus gains electrons to form nadph gaining electrons is called reduction and
Is NADP+ an electron carrier?
Yes, NADP is an electron carrier. It accepts electrons and gets reduced to NADPH. It is involved in various metabolic processes such as the electron transport chain occurring in the chloroplast.
What is the difference between NADP+ and NADPH?
Nicotinamide adenine dinucleotide phosphate, or NADP+, is a similar molecule with a similar function, differing from NAD+ in that it contains an additional phosphate group. The oxidized form is NADP+, while the reduced form is NADPH.
Is NADH an electron carrier?
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.
Is NADPH the same as NADH?
NADPH and NADH are coenzymes, which take part in various metabolic processes. NADPH contains an extra phosphate group. NADH is involved in cellular respiration, whereas NADPH is involved in photosynthesis. NADPH and NADH are the reduced forms of NADP+ and NAD+, respectively.
Does NAD+ or NADH carry electrons?
The nitrogenous base in NADH has one more hydrogen ion and two more electrons than in NAD+. NAD+ is used by the cell to "pull" electrons off of compounds and to "carry" them to other locations within the cell; thus it is called an electron carrier.
How many electrons and protons does NADH carry?
| NADH | ~10 protons pumped | ~ 3 ATP |
|---|---|---|
| FADH2 | ~6 protons pumped | ~2 ATP |
How many electrons does NADH and FADH2 carry?
Both NADH and FADH2 donate two electrons to the electron transport chain, so theoretically they should make the same amount of ATP. However, NADH donates its electrons to complex I while FADH2 donates its electrons further "downstream" at complex II.
Are NADH and NADPH electron carriers?
Both NAD and NADH are involved in cellular metabolism. Both NADH and NADPH serve as hydrogen and electron donors.
What is the difference between NAD+ and NADPH?
The key difference between NAD+ NADH and NADPH depends on the form in which they exist. NAD+ is in the oxidized form while NADH is in the reduced form. On the other hand, NADPH is a reducing agent that has an additional phosphate group than NADH.
How is NADP+ related to NADPH?
NADPH is produced from NADP+. The major source of NADPH in animals and other non-photosynthetic organisms is the pentose phosphate pathway, by glucose-6-phosphate dehydrogenase (G6PDH) in the first step. The pentose phosphate pathway also produces pentose, another important part of NAD(P)H, from glucose.
How many electrons does NADH deliver?
The overall plan is this: NADH delivers two electrons to a series of chemicals that differ in their chemical affinity for these electrons (see Figure 2.10.
Does NADH carry 2 electrons?
Nicotinamide adenine dinucleotide (NAD+) (the structure is shown below) is derived from vitamin B3, niacin. NAD+ is the oxidized form of the molecule; NADH is the reduced form of the molecule after it has accepted two electrons and a proton (which together are the equivalent of a hydrogen atom with an extra electron).
How many electrons do NADH and FADH2 carry?
two electrons Both NADH and FADH2 donate two electrons to the electron transport chain, so theoretically they should make the same amount of ATP.
