What else can I help you with?
What structure that is found in the thylakoid membrane is important to chemiosmosis?
ATP synthase is the structure found in the thylakoid membrane that is important for chemiosmosis. It is responsible for generating ATP by utilizing the proton gradient created during the photosynthetic electron transport chain.
What is the electron acceptor for humans in the electron transport chain?
The electron acceptor for humans in the electron transport chain is oxygen.
Which sequence accurately describes the flow of electrons in photosynthesis?
In photosynthesis, electrons flow from water to photosystem II, then to photosystem I, and finally to NADP+ to produce NADPH. This flow of electrons is facilitated by the electron transport chain within the thylakoid membrane of the chloroplast.
In which membrane is the electron transport chain located?
The outer membrane is where the electron transport chain is located.
In prokaryotes the electron transport chain is in the what?
Electron transport chains are located there are many different electron donors and electron acceptors. Reverse electron transport is the most important in prokaryotic electron transport chains.
Photosynthetic electron transport in cyanobacteria takes place where?
Photosynthetic electron transport in cyanobacteria takes place in thylakoid membranes within the chloroplasts. These membranes contain the pigment chlorophyll, which captures light energy. The electron transport chain within these membranes is essential for the generation of ATP and NADPH, which are used in the production of carbohydrates during photosynthesis.
What DCMU inhibits electron transport in chloroplast by preventing the reduction?
DCMU (3-(3,4-dichlorophenyl)-1,1-dimethylurea) inhibits electron transport in chloroplasts by blocking the plastoquinone binding site in photosystem II. This prevents the reduction of plastoquinone and disrupts the flow of electrons in the photosynthetic electron transport chain. As a result, the light-dependent reactions of photosynthesis are impaired, leading to decreased ATP and NADPH production. Consequently, this inhibition affects overall photosynthetic efficiency and plant growth.
What is the incoming energy source for electron transport chain?
The electron transport chain is the driving energy behind ATP synthesis. The energy itself comes from electron donors. In chloroplast, this donor's glucose.
What does the ETC do in plants?
Photosynthetic ETC takes place in thylakoid membranes membranes in chloroplast. Like ETC in mitochondria, light reaction in photosynthesis transport electrons across the photosystems. This yields high energy electron donor, NADPH (unlike in oxidative phosporylation where electrons are transferred from electron donor NADH)
When and where does the electron transport take place?
The location of the electron transport system depends on the cell type.~The electron transport system is embedded in the inner membrane of the mitochondria for animal, plant and fungus cells.~The electron transport system is also in the thylakoid membrane of chloroplasts in plant cells.
How many electron transport chains are there in photosynthesis?
There is one electron transport chain in photosynthesis, which is located in the thylakoid membrane of the chloroplast. This electron transport chain is responsible for transferring electrons and generating ATP and NADPH during the light-dependent reactions of photosynthesis.
What 2 things go with the mitochondria and chlorolast?
Mitochondria: Glycolosis, The Krebs cycle, and the electron transport chain complete cellular respiration Chloroplast: Photosynthesis takes place in the Stroma and the electron transport chain.
Is chlorohpyll an ATP molecule?
no, its a photosynthetic pigment which supports an electron transport chain which eventually leads to the synthesis of ATP in plants
Where does cyclic electron transport occur?
Cyclic electron transport occurs in the thylakoid membrane of chloroplasts during the light reactions of photosynthesis. It involves the flow of electrons through the photosynthetic electron transport chain to generate ATP without the production of NADPH.
Where is the electron transport systems used to make ATP located?
The electron transport system used for ATP synthesis happens in the inner membrane of the mitochondrion and the proteins embedded within that membrane.
Where does electron transport in photosynthesis take place?
Electron transport in photosynthesis takes place in the thylakoid membrane of the chloroplast. It involves a series of protein complexes that transfer electrons along a chain, creating a proton gradient that drives ATP synthesis and ultimately produces NADPH for the Calvin cycle.
What is composed of a light-harvesting complex and an electron transport system?
A photosystem is composed of a light-harvesting complex and an electron transport system. The light-harvesting complex captures light energy and transfers it to the reaction center, where electrons are excited and transferred through the electron transport system to generate ATP and NADPH during photosynthesis.
