Favorite Answer. Because light energy powers this reaction in the chloroplasts, the production of ATP during photosynthesis is referred to as photophosphorylation, as opposed to oxidative phosphorylation in the electron-transport chain in the mitochondrion . An electron first begins photosynthesis in Photosystem II (a chlorophyll molecule also known as p680). ? 111) The electron transport chains of the light reactions 111) A) are found on the plasma membrane of mesophyll cells. Because the P860 is missing a negative charge, its is P860+ d) An enzyme splits water into hydrogen and oxygen, these electrons are supplied to a P860+ pair, each electron replacing one transferred to the primary electron acceptor. Chlorophyll is therefore said to “donate” an electron (Figure 5.12). H+ is released into the thylakoid space. Light energy is needed to make ATP and NADPH. The photon excites one of the chlorophyll a electrons to a higher energy state. A) electrons passing down the electron transport chain. carotenoid.

Photosystems II and I contain many pigments which absorb energy from photons of light from the sun and transfers it to P680 (in photosystem II) and P700 (in photosystem I). This leaves the chlorophyll with an electron imbalance, which it rectifies by taking a low-energy electron from a water molecule. What is the phenomenon called where one group gains knowledge of something and suddenly every other group now knows how to do that thing ?

What is your purpose in the environment as a human being. If life evolved from 2 or more different sources, would we know it? Answer Save. The photon causes an electron in the chlorophyll to become “excited.”. The energy passes rapidly from molecule to molecule until it reaches a special chlorophyll molecule called P700, so named because it absorbs light in the red region of the spectrum at wavelengths of 700 nanometers. ? Q. B) subdivides the eukaryotes into two different domains. 0 1. kindsoulz. photons. Excited electrons “fall” down the electron transport chain from the primary electron acceptor of Photosystem I to the protein ferredoxin. Are we going through an evolution with the Coronavirus Pandemic. B) ATP. This electron is captured by the primary acceptor of the reaction centre. michelle. Photosynthesis (photos-light, synthesis-putting together) is an anabolic process of manufacture of organic compounds inside the chlorophyll containing cells from carbon dioxide and water with the help of sunlight as a source of energy. For the best answers, search on this site https://shorturl.im/bwSwS. Report question . 110) The energy that excites the photosystems is supplied by 110) A) electrons passing down the electron transport chain. expand. Created by: Gladys Hampton. The photosystems are the functional centers of photosynthesis. This reaction requires a substantial input of energy, much of which is captured in the bond that links the added phosphate group to ADP. The energy that excites the photosystems is supplied by. 1 decade ago. Sunday, January 9, 2011. It is C. Photosystems II and I contain many pigments which absorb energy from photons of light from the sun and transfers it to P680 (in photosystem … In Photosystem II - the electrons are sent down the electron transport pathway. Relevance. The photosystems responsible for absorption of light energy are each composed of two linked components, the reaction center and an antenna complex. It is C.
