Photosystems

photosystems Photosynthesis occurs in 3 main stages: energy is captured from sunlight, thus it’s converted into chemical energy and stored in organic iotas. Photosystems are light harvesting units of the thylakoid tissue layer. Each photosystem has four snow paint molecules. A photon hits the pigment molecules and travels through each molecule and then reaches the reaction center as shown in elaborate 1-1. The thylakoid membrane has two photosystems, photosystem 1 & 2. The reaction center in photosystem 1 is called P700 because this pigment is best at engrossing 700 mm light.

Photosystem 2’s reaction center is called P680 because it is best at absorbing 680 mm light. Calvin Cycle The Calvin cycle begins by incorporating carbon dioxide from the variant into molecules in the chloroplast. This action is called carbon fixation. The next subject it does is chalk up electrons to the fixed carbon to make it carbohydrate. The world power of the Calvin cycle comes from NADPH.
