What molecule is produced when 2 electrons and one proton are added to NADP?

Explanation: The molecule produced In biochemical reactions, NADP+ acts as a “hydride” acceptor. The hydrogen atom adds to the nicotinamide ring, converting the molecule to NADPH. by adding two electrons and one proton to NADP plus is NADPH.

How many protons and electrons can NADP+ Accept?

NADP+ will be able to accept one hydrogen and two electrons, or (H–). Together, these will create the electrically neutral molecule NADPH. There remains a hydrogen with no electrons, or a free proton.

What is the source of protons necessary for reduction of NADP+?

The electrons taken from water are driven through electron transport. The protons remain in the thylakoid lumen, which is where the water oxidation occurs. NADP+ is reduced at the end of photosynthetic electron transport by the electrons originally taken from water. Each NADP+ receives 2 e-.

How does NADP+ become NADPH?

Photosynthesis uses a different energy carrier, NADPH, but it functions in a comparable way. The lower energy form, NADP+, picks up a high energy electron and a proton and is converted to NADPH. When NADPH gives up its electron, it is converted back to NADP+.

What is produced in photosystem 2?

Photosystem II obtains replacement electrons from water molecules, resulting in their split into hydrogen ions (H+) and oxygen atoms. The oxygen atoms combine to form molecular oxygen (O2), which is released into the atmosphere. The hydrogen ions are released into the lumen.

Where does photosystem 2 get its electrons?

In (a) photosystem II, the electron comes from the splitting of water, which releases oxygen as a waste product. In (b) photosystem I, the electron comes from the chloroplast electron transport chain discussed below.

Is NADP an electron carrier?

NADP+ is an electron carrier that can reduce other molecules in biosynthetic reactions. In biological systems, the more reduced a molecule, the more potential it has to yield energy when it’s broken down. NADP+/NADPH’s role in the cell is to donate those electrons so that the cell can make things.

Is NADH an electron carrier?

NADH is the reduced form of the electron carrier, and NADH is converted into NAD+. This half of the reaction results in the oxidation of the electron carrier.

What are the two types of Photophosphorylation?

Only two sources of energy are available to living organisms: Sunlight and reduction-oxidation (redox) reactions. Photophosphorylation is of two types: Non-Cyclic Photophosphorylation and Cyclic Photophosphorylation. ) to be pumped into the thylakoid space. by electrons coming from photo-oxidation of water.

What would happen if chloroplast ran out of NADP+?

What would you expect would happen if this chloroplast ran out of available NADP+? The organism would not be able to produce NADPH, but will be able to produce ATP.

Is NADP+ an electron carrier?

NADP+/NADPH uses its electrons to build things that are involved in anabolic or biosynthetic pathways. NADP+ is an electron carrier that can reduce other molecules in biosynthetic reactions. In biological systems, the more reduced a molecule, the more potential it has to yield energy when it’s broken down.

What is the difference between NADP+ and Nadph?

What is the diff between NADP+ and NADPH? NADPH is an energy molecule. NADP+ is an e- acceptor. It turns into NADPH by accepting both e- and H+ molecules.

How many ATPs are synthesized in one NADPH2 molecule?

And 2 NADPH2 are formed by combination of NADP negative and protons ( protons obtained by splitting of water). 1 NADPH2 molecule gives 3 atps. Hence 3 will give 6 atps + 1 atp that equals 7 atps.

How are ATPs synthesized in one non-cyclic molecule?

One ATP molecule is produced by electron transfer from cytochrome b6 to cytochrome f. And 2 NADPH2 are formed by combination of NADP negative and protons ( protons obtained by splitting of water). 1 NADPH2 molecule gives 3 atps. Hence 3 will give 6 atps + 1 atp that equals 7 atps.

How many ATP molecules are produced per glucose molecule?

17. Out of 38 ATP molecules produced per glucose, 32 ATP molecules are formed from NADH/FADH2 in (c) oxidative decarboxylation (d) EMP. 17. (a): During respiratory chain, complete degradation of one glucose molecule produced 38 ATP molecules.

Which is the primary electron acceptor of P700?

When the photons activate P700 reaction centre photosystem II is activated. Electrons are raised to the high energy level. The primary electron acceptor is Ferredoxin Reducing Substance (FRS) which transfers electrons to Ferredoxin (Fd), Plastoquinone (PQ), cytochrome b6-f complex, Plastocyanin (PC) and finally back to chlorophyll P700 (PS I).
