WebWhen photosystem I absorbs light, an electron is excited to a higher energy level in the P700 chlorophyll. The resulting P700 with an excited electron is designated as P700*, which is a strong reducing agent due to its very negative redox potential of -1.2 V. [8] Electron transport chain [ edit] WebJun 10, 2024 · The primary role of chlorophyll is to absorb light energy for use in a process called photosynthesis — the process by which plants, algae and some bacteria convert light energy from the sun into chemical energy. Light is …
WebThe chlorophyll a special pairs of the two photosystems absorb different wavelengths of light. The PSII special pair absorbs best at 680 nm, while the PSI special absorbs best at 700 nm. Because of this, the special pairs are called P680 and P700, respectively. … Besides introducing fixed carbon and energy into ecosystems, photosynthesis … Cellular respiration is the process by which cells derive energy from glucose.
