WebThere are two types of photosystems: photosystem I and photosystem II. Under the light-dependent reactions, the light energy is converted to ATP and NADPH, which are used in the second phase of photosynthesis. During the light reactions, ATP and NADPH are generated by two electron-transport chains, water is used and oxygen is produced. Web3.3.2 Photosystems. Photosystems are the functional units for photosynthesis, defined by a particular pigment organization and association patterns, whose work is the absorption and transfer of light energy, which implies transfer of electrons. Physically, photosystems are found in the thylakoid membranes. There are two kinds of photosystems ...

Difference Between Photosystem I and Photosystem II

Photosystem - Wikipedia

WebMost of the pigments in a photosystem act as an energy funnel, passing energy inward to a main reaction center. When one of these pigments is excited by light, it transfers energy to a neighboring pigment through direct electromagnetic interactions in a process called … Besides introducing fixed carbon and energy into ecosystems, photosynthesis … Cellular respiration is the process by which cells derive energy from glucose. The … WebPhotosystem II is first in the process of the light-dependent reactions of photosynthesis, but it has a 'II' after its name because it was discovered second.
