Difference Between Photosystem 1 and 2

The two main multi-subunit membrane protein complexes differ in their absorbing wavelength, where the photosystem I or PS 1 absorbs the longer wavelength of light which is 700 nm while photosystem II or PS 2 absorbs the shorter wavelength of light 680 nm.

What is the difference between ps1 and ps2?

Photosystem I (PS I) and photosystem II (PS II) are two multi-subunit membrane-protein complexes involved in oxygenic photosynthesis. ... The main difference between photosystem 1 and 2 is that PS I absorbs longer wavelengths of light (>680 nm) whereas PS II absorbs shorter wavelengths of light (<680 nm).

What is the difference between photosystem I and photosystem II quizlet?

What is the difference between Photosystem II and Photosystem I? Photosystems II and I have different chlorophylls. PS II has P680 and PS I has P700. Photosystem II comes before Photosystem I.

What is the function of photosystem II and photosystem I?

Two large membrane protein complexes, photosystems I and II (abbreviated as PS I and PS II, respectively) are embedded in this membrane. They catalyze the initial step of photosynthesis, the light induced charge separation across the photosynthetic membrane.

What are the products of photosystem 1 and 2?

The most common light-dependent reaction in photosynthesis is called noncyclic photophosphorylation. Noncyclic photophosphorylation involves both Photosystem I and Photosystem II and produces ATP and NADPH.

What is the main role of photosystem I?

Photosystem I is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from plastocyanin to ferredoxin. Ultimately, the electrons that are transferred by Photosystem I are used to produce the high energy carrier NADPH.

What happens in photosystem II?

Photosystem II is the first link in the chain of photosynthesis. It captures photons and uses the energy to extract electrons from water molecules. ... As these electrons flow down the chain, they are used to pump hydrogen ions across the membrane, providing even more power for ATP synthesis.

What is the end product of photosystem I?

ATP is the product of photosystem I.

What is the product of 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.

Does photosystem produce ATP?

This is accomplished by the use of two different photosystems in the light reactions of photosynthesis, one to generate ATP and the other to generate NADPH. Electrons are transferred sequentially between the two photosystems, with photosystem I acting to generate NADPH and photosystem II acting to generate ATP.

What is the main function of photosystem 2?

Photosystem II (PSII) is a multi-component pigment-protein complex that is responsible for water splitting, oxygen evolution, and plastoquinone reduction.

What is the most important function of PS II?

The most important of PS II is splitting of water and evolution of molecular oxygen.
