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). Ben Joan. Photosystem II (P680) 1) Absorption spectrum peaks at 680 nanometers (red part of the spectrum) 2) Shuffles electrons to a QUINONE terminal electron acceptor. Heat of formation of ethane -20.2 kcal moll andheat of atomisation of C and H, are 179.2 kcalmol and 52.1 kcal moll respectively. Although it seems to go against logical reasoning, photosystem II begins the process of photosynthesis by removing an electron from water molecules and breaking it down to oxygen and hydrogen. However, they are both equally important in … The excited electron then produces a NADPH molecule which is used by the Calvin cycle. Key Differences Between Photosystem I and Photosystem II The light-harvesting pigments of photosystem I and II absorb photons having wavelengths of 700 nm (P700) and wavelengths of 680 nm (P680), respectively. The only major difference between photosystem I and photosystem II is of the wavelength of light that is absorbed by it.

PS 1 sadrži klorofil B, klorofil A-670, klorofil … It is responsible for catalyzing the first stage of light reaction. Difference # Photosystem II (PS II): 1. On the other hand, the photosystem II has a reaction centre comprising chlorophyll a molecule of P680 that absorbs light at a wavelength of 680 nm. Glavna razlika - Photosystem 1 vs 2. Photosystem II (P680) 1) Absorption spectrum peaks at 680 nanometers (red part of the spectrum) 2) Shuffles electrons to a QUINONE terminal electron acceptor. It is responsible for facilitating the final stage of light reaction. That will energize electrons and give to primary acceptor molecule to pass down ETC to make ATP through proton motive force and those electrons will fill in the holes of photosystem 1. 3. The process of photolysis … Photosystem I produces a strong reductant, capable of reducing NADP', and a weak oxidant. It just so happened that photosystem I was the first one to be discovered by scientists and thus given the designation. Photosystem II (PS II) is involved only in non-cyclic photophosphorylation. There are two types of photosystems photosystem I (PS I) and photosystem II (PS Il). recent questions recent answers. Photosystem I: It has chlorophyll a molecules.
