WebDec 27, 2024 · Introduction. CO 2 is reduced and assimilated into carbon rich molecules via photosynthesis, 30%–60% of which are oxidized by respiration and released back to the environment as CO 2 during the plant lifecycle (Raich et al., 2014; Amthor et al., 2024).Beyond this simple comparison, however, the systems that underlie photosynthetic … WebCarbon dioxide (CO2) is the primary greenhouse gas emitted through human activities.

WebPhotoautotrophs use specialized structures during photosynthesis, some that capture CO 2 and H 2 O and then release O 2 called stomata, and some that capture light energy called chlorophyll. The stomata are small openings, typically on the underside of leaves (minimizes water loss), that are surrounded by cells that respond to osmotic changes. WebThe ultimate goal of photosynthesis is to store converted light energy (sun) into stable chemical energy (chemical bonds). Light “sun” energy will be initially captured by light absorbing pigments (chlorophyll) in the form of excited electrons. Those excited electrons possess lots of absorbed energy which needs to be captured.

WebWhen a photon raises a chlorophyll electron to a higher energy level, that energy, and ultimately an electron, has to go somewhere. That somewhere, ideally for the photosynthesizing organism, is known as the Primary Electron Acceptor. The reducing agent is called pheophytin and is a derivative of chlorophyll itself. WebThe light excites an electron from the chlorophyll a pair, which passes to the primary electron acceptor. The excited electron must then be replaced. In photosystem II, the electron comes from the splitting of water, which releases oxygen as a waste product. In photosystem I, the electron comes from the chloroplast electron transport chain.
