How does the ETC work in photosynthesis?
In plants and other photosynthetic organisms, an ETC serves to oxidize NADPH (a phosphorylated version of the electron carrier NADH). In both cases, free energy released when the redox reactions of an ETC are coupled to the active transport of protons (H+ ions) across a membrane.
Where is the ETC in photosynthesis?
thylakoid membrane
In photosynthetic eukaryotes, the electron transport chain is found on the thylakoid membrane.
Is the electron transport chain used in photosynthesis?
The photosynthetic electron transport chain consists of photosystem II, the cytochrome b6f complex, photosystem I, and the free electron carriers plastoquinone and plastocyanin.
What is the purpose of the ETC?
What is the purpose of the ETC? The main purpose of the electron transport chain is to build up a surplus of hydrogen ions (protons) in the intermembrane space sp that there will be a concentration gradient compared to the matrix of the mitochondria. This will drive ATP synthase.
What is the substrate of ETC?
NADH, FADH2, oxygen (O2), ADP, Pi (phosphate) are used as substrates. On the other hand ATP, NAD+, FAD and H2O are produced as a result of oxidative phosphorylation reactions.
What does the ETC do?
The ETC is a collection of proteins bound to the inner mitochondrial membrane and organic molecules, which electrons pass through in a series of redox reactions, and release energy. The energy released forms a proton gradient, which is used in chemiosmosis to make a large amount of ATP by the protein ATP-synthase.
Where is the ETC in the chloroplast?
ETC in chloroplasts takes place in the thylakoid membrane of the chloroplast.
Do plants have electron transport chain?
By moving through the protein they give it power, like water moving through a dam. When hydrogen ions move through the protein and down the electron transport chain, ATP is created. This is how plants turn to sunlight into chemical energy that they can use.
Is ETC aerobic or anaerobic?
aerobic respiration
The electron transport chain is the portion of aerobic respiration that uses free oxygen as the final electron acceptor of the electrons removed from the intermediate compounds in glucose catabolism.
What are the three electron carriers in ETC?
Abstract: The electron transport chain (ETC) is the major consumer of O2 in mammalian cells. The ETC passes electrons from NADH and FADH2 to protein complexes and mobile electron carriers. Coenzyme Q (CoQ) and cytochrome c (Cyt c) are mobile electron carriers in the ETC, and O2 is the final electron recipient.
What is Q cycle in ETC?
The Q cycle (named for quinol) describes a series of reactions that describe how the sequential oxidation and reduction of the lipophilic electron carrier, Coenzyme Q10 (CoQ10), between the ubiquinol and ubiquinone forms, can result in the net movement of protons across a lipid bilayer (in the case of the mitochondria.
What is photosynthesis?
Photosynthesis is the process used by the plants to make their food. In simpler terms, conversion of light energy into chemical energy by plants is called photosynthesis. This chemical energy is used by the plants for growth and nourishment.
What are the complexes in the electron transport chain of photosynthesis?
The following complexes are found in the photosynthesis electron transport chain: Photosystem II, Cytochrome b6-f, Photosystem I, Ferredoxin NADP Reductase (FNR), and the complex that makes ATP, ATP Synthase. In addition to the complexes, three mobile carriers are also involved: Plastoquinone Qb, Plastocyanin, and Ferredoxin.
What is the final product of photosynthesis?
This is similar to the way ATP is synthesized in the mitochondria. ATP, NADPH, and molecular oxygen are the final, vital, products of photosynthesis. Review the animation at your own pace… View slides from the animation labeled with additional information.
What are the main components of photosynthesis?
Other key components include: photons, chlorophyll molecules, protons, water, molecular oxygen, NADP+ and the electrons to form NADPH, and ADP and Pi, which combine to form ATP. Photosynthesis occurs in the chloroplasts of plants and algae. The process is also found in single-cell organisms such as cyanobacteria that do not have chloroplasts.
