thylakoids
The series of molecules through which excited electrons are passed down a thylakoid membrane during photosynthesis is called the electron transport chain. This chain consists of various protein complexes and molecules, such as plastoquinone, cytochrome b6f complex, and plastocyanin, that work together to transfer electrons and generate a proton gradient used to produce ATP.
An electron transport chain.
electron transport chain
The series of electron acceptors in the thylakoid membrane that remove energy from excited electrons to produce ATP is known as the electron transport chain (ETC). As electrons move through the ETC, their energy is used to pump protons across the membrane, creating a proton gradient. This gradient drives ATP synthesis through ATP synthase.
electron transport chain
Excited electrons in a chlorophyll molecule are transferred through a series of proteins in the thylakoid membrane, known as the electron transport chain, generating ATP and NADPH through the process of photosynthesis. These high-energy molecules will then be used in the Calvin cycle to produce glucose from carbon dioxide.
Light energy is absorbed by chlorophyll and other pigments in the photosystem, exciting electrons. These excited electrons are passed through a series of electron carriers in the thylakoid membrane, creating a proton gradient across the membrane. The electrons ultimately replace those lost by chlorophyll through splitting water molecules, releasing oxygen as a byproduct. ATP is produced as a result of the proton gradient, which is used to power the Calvin cycle for glucose synthesis.
The series of electron acceptors in the thylakoid membrane is known as the electron transport chain. As electrons move through the chain, they lose energy, which is used to pump protons across the membrane, creating a proton gradient. This gradient is then used by ATP synthase to produce ATP through a process known as chemiosmosis.
Ultraviolet Light
the reaction center.
Water is split in the light reactions of photosynthesis to provide electrons for the photosynthetic electron transport chain. This process releases oxygen as a byproduct. Additionally, water molecules help maintain the balance of protons and electrons within the thylakoid membrane during the light reactions.
