is psi needed to make nadph?

Together, PSI and PSII move electrons from water to NADP+, forming NADPH. ... The thylakoid membrane uses the flow of electrons through the transport chain between PSII and PSI to pump hydrogen ions (protons) from the stroma into the thylakoid space.

The ATP and NADPH from the light-dependent reactions are used to make sugars in the next stage of photosynthesis, the Calvin cycle. In another form of the light reactions, called cyclic photophosphorylation, electrons follow a different, circular path and only ATP (no NADPH) is produced.

The ATP and NADPH produced by the light reactions power sugar synthesis in the Calvin cycle. ... Thus, the Calvin cycle uses ATP and NADPH to convert three molecules of CO2 to one molecule of a 3-carbon sugar. The plant can then use this small sugar to make larger sugars such as glucose and many other organic compounds.

What is absolutely required for this to operate? The electron transport chain will oxidize NADH and FADH, transferring the electrons to the carrier proteins in the ETC. This will create a proton gradiant which fuels ATP synthase to produce ATP molecules. THIS PROCESS REQUIRES OXYGEN!!

Nicotinamide adenine dinucleotide (NAD+) and flavin adenine dinucleotide (FAD+) are two cofactors that are involved in cellular respiration. They are responsible for accepting "high energy" electrons and carrying them ultimately to the electron transport chain where they are used to synthesize ATP molecules.

39g of benzene will be required to burn =(336/156)*39 litres of oxygen at STP. =84 litres of oxygen at STP. That is the answer.

Explanation: Know that one mole of any gas at STP takes up 22.4 liters. So 2.4 L of hydrogen is 0.107142857molsH2 . Since H2 reacts with O2 in a 2:1 ratio, to completely react the two you will need half as much oxygen as hydrogen.

The ATP generated in this process is made by substrate-level phosphorylation, which does not require oxygen. Fermentation is less efficient at using the energy from glucose: only 2 ATP are produced per glucose, compared to the 38 ATP per glucose nominally produced by aerobic respiration.

NADPH stands for nicotinamide adenine dinucleotide phosphate hydrogen. ... NADPH is a product of the first stage of photosynthesis and is used to help fuel the reactions that take place in the second stage of photosynthesis. Plant cells need light energy, water and carbon dioxide to carry out the steps of photosynthesis.

Do Neon Tetras Need an Air Pump? Air pumps force oxygen into the tank so fish can breathe. In most cases, neon tetras do not require any extra oxygen and can do well in an aquarium without an air pump.

Water will first be broken down into 4H+ ions and 4e- (electrons) and oxygen. ... So in non-cyclic photophosphorylation, you make oxygen, from splitting the water molecule, you make ATP using the H+ ions and you make NADPH. In cyclic photophosphorylation, you only use photosystem I.

It exists in either an oxidized form, NAD+, which can accept a hydrogen atom (i.e., a proton), or a reduced form, NADH, which can donate a hydrogen atom. ... The oxidized form is NADP+, while the reduced form is NADPH.

N2 is found in a 1-litre flask under 100 kPa pressure and O2 is found in another 3-litre flask under 320 kPa pressure. If the two flasks are connected, what is the resultant pressure? There are 40 ml of air in a large syringe. With the exit hole plugged, you squeeze the air down to about 10 ml.

How many ATPs are in 1 NADPH? - Quora. Since NADH is worth 2.5 (3) ATP and by removing the phosphate from NADPH you get NADH + 1 ATP the grand total worth of NADPH is 3.5 (4) ATP [relative to NAD+].

In cellular respiration, there are two important electron carriers, nicotinamide adenine dinucleotide (abbreviated as NAD+ in its oxidized form) and flavin adenine dinucleotide (abbreviated as FAD in its oxidized form). ... NAD+ accepts a hydrogen ion (H+) and two electrons (2e−), as it becomes reduced to NADH + H+.
