Q. Where does electron transport occur?
-The electron transport system takes place in the cristae present in the inner membrane of the mitochondria. Cristae are the infoldings of the inner membrane of the mitochondria and it aids in the cellular respiration. It contains a number of cytochromes and enzyme ATP synthase.
Q. Where does electron transport occur during cellular respiration?
The Krebs cycle and electron transport occur in the mitochondria. The Krebs cycle takes place in the matrix, and electron transport takes place on the inner membrane.
Q. Where does electron transport occur in humans?
mitochondria
Q. Where does ETS occur in mitochondria?
inner mitochondrial membrane
Q. What are the two types of Photophosphorylation?
Photophosphorylation is of two types:
- Cyclic Photophosphorylation.
- Non-cyclic Photophosphorylation.
Q. What are the products of electron transport?
The end products of the electron transport chain are water and ATP. A number of intermediate compounds of the citric acid cycle can be diverted into the anabolism of other biochemical molecules, such as nonessential amino acids, sugars, and lipids.
Q. How is ATP produced in electron transport?
The proton gradient produced by proton pumping during the electron transport chain is used to synthesize ATP. Protons flow down their concentration gradient into the matrix through the membrane protein ATP synthase, causing it to spin (like a water wheel) and catalyze conversion of ADP to ATP.
Q. How much ATP does electron transport produce?
A total of 32 ATP molecules are generated in electron transport and oxidative phosphorylation.
Q. What are the products of the electron transport quizlet?
Terms in this set (10)
- Reactants and products of ETC. Electron Transport reactants: Hydrogen ions, oxygen, NADH, FADH2 Products:Water and ATP( 2 e- + 2 H+ 1/2 O2= H20)

Q. Is oxygen a product of the electron transport chain quizlet?
Glycolysis and the Krebs cycle produce the molecules that shuttle electrons to the electron transport chain. Oxygen is a product of the electron transport chain. oxidizes glucose and reduces oxygen.
Q. Is water a reactant of electron transport chain?
Water is formed when hydrogen and oxygen react to form H2O during the electron transport chain, which is the final stage of cellular respiration.
Q. What is the role of the electron transport chain?
The electron transport chain is used to pump protons into the intermembrane space. This establishes a proton gradient, allowing protons to be pumped through ATP synthase in order to create ATP. This method of ATP production is called oxidative phosphorylation.
Q. What are the stages of electron transfer phosphorylation?
The three major steps in oxidative phosphorylation are (a) oxidation-reduction reactions involving electron transfers between specialized proteins embedded in the inner mitochondrial membrane; (b) the generation of a proton (H+) gradient across the inner mitochondrial membrane (which occurs simultaneously with step (a …
Q. What are the products of oxidative phosphorylation?
The products of oxidative phosphorylation are ATP, NAD+, and FAD+.
Q. Which is the end product of oxidative phosphorylation?
-The transfer of an electron to molecular oxygen combines with H+ to form water is marked as an end product in the oxidative phosphorylation pathway. So, the correct answer is, ‘ATP+H2O.
Q. What is the first step in oxidative phosphorylation?
oxidation
Q. Which is the location of electron transport systems in prokaryotes?
The cytoplasmic membrane is the location of electron transports systems in prokaryotes.
Q. What are the electron carriers?
Electron carriers, also called electron shuttles, are small organic molecules that play key roles in cellular respiration. Their name is a good description of their job: they pick up electrons from one molecule and drop them off with another.
Q. Do prokaryotes use electron transport chain?
The electron transport chains of bacteria (prokaryotes) operate in plasma membrane (mitochondria are absent in prokaryotes). Since most bacteria grow anaerobically using different variety of electron acceptor substances, the bacterial electron transport chains are frequently very different.
