WebDec 5, 2024 · As the light intensity increases, the rate of photosynthesis also increases. However, there is a point at which the rate of photosynthesis levels off. This is because … WebWhen light is absorbed by one of the pigments in photosystem II, energy is passed inward from pigment to pigment until it reaches the reaction center. There, energy is transferred to P680, boosting an electron to a high energy level (forming P680*). The high-energy electron is passed to an acceptor molecule and replaced with an electron from water. WebBesides introducing fixed carbon and energy into ecosystems, photosynthesis also affects the makeup of Earth’s atmosphere. Most photosynthetic organisms generate oxygen gas as a byproduct, and the advent of photosynthesis—over 3 3 3 3 billion years ago, in bacteria resembling modern cyanobacteria—forever changed life on Earth 1 ^1 1 start superscript, … rcc boot barn
