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.
Which process does this animal rely on to produce most of its ATP molecules?
Electron transport chains
Define the electron transport chain and describe its location and purpose?
An electron transport chain(ETC) couples a chemical reaction between an electron donor (such as NADH) and an electron acceptor (such as O2) to the transfer of H+ ions across a membrane, through a set of mediating biochemical reactions. These H+ ions are used to produce adenosine triphosphate (ATP), the main energy intermediate in living organisms, as they move back across the membrane. Electron transport chains are used for extracting energy from sunlight (photosynthesis) and from redox reactions such as the oxidation of sugars (respiration). In chloroplasts, light drives the conversion of water to oxygen and NADP+ to NADPH and a transfer of H+ ions. NADPH is used as an electron donor for carbon fixation. In mitochondria, it is the conversion of oxygen to water, NADH to NAD+ and succinate to fumarate that drives the transfer of H+ ions. While some bacteria have electron transport chains similar to those in chloroplasts or mitochondria, other bacteria use different electron donors and acceptors. Both the respiratory and photosynthetic electron transport chains are major sites of premature electron leakage to oxygen, thus being major sites of superoxide production and drivers of oxidative stress.
Where is the electron transport chain is found in eukaryotes?
Electron transport occurs in the mitochondria of eukaryotic cells. Specifically, the four protein complexes of the electron transport chain (ETC) exist as transmembrane complexes in the inner membrane of the mitochondria.
What is the innermost membrane?
pia mater
What do mitochondrial and thylakoid membranes ave in common?
Mitochondrial and thylakoid membranes are sites of electron transport chains. They both use ATP synthase proteins in ATP production.
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.
What are the product from the electron transport chain pathway?
Electron transport chains are present in mitochondria. The products of the electron transport chains are energy in the form of thermodynamics and water which is reduced from oxygen.
Where is the site of Electron transport chain in the tissue?
In the inner membranes of mitochondria, an organelle with thousands of electron transport chains.
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.
How many electron transport chains does photosynthesis use?
42
What does NADP mean relating to biology?
It is an electron acceptor in the electron transport chains in the light reactions.
Where are most of the ATP produced in the aerobic respiration?
Electron transport chains
The electron transport chains of cellular respiration are located?
This depends on whether you are a eukaryote, bacteria or archaea. In eukaryotes, the electron transport chain components are on the mitochondrial membrane.In bacteria and archaea, since there are no membrane-enclosed compartments, they are on the cellular membrane.
Where are most of the ATP molecules produced in aerobic reparation?
Electron transport chains
Where are the most ATP molecules produce in aerobic respiration?
Electron transport chains
At the DNA synthesis G2 checkpoint DNA replication is checked by 1 receptor proteins 2 Repair enzymes 3 electron transport chains 4 cell surface markers?
2 Repair enzymes. At the DNA synthesis G2 checkpoint, DNA replication is checked by repair enzymes that detect and repair any mistakes in the replicated DNA before the cell progresses to mitosis. Receptor proteins, electron transport chains, and cell surface markers are not directly involved in checking DNA replication at this checkpoint.
