What does the ETC produce?
The electron transport chain (aka ETC) is a process in which the NADH and [FADH2] produced during glycolysis, β-oxidation, and other catabolic processes are oxidized thus releasing energy in the form of ATP.
What are the products of ETC?
The products of the electron transport chain are NAD+, FAD, water, and ATP. As NADH and FADH2 donate electrons to protein complexes, the protons are also released from these molecules.
Is ETC aerobic or anaerobic?
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.
How is ATP produced in electron transport?
The process of forming ATP from the electron transport chain is known as oxidative phosphorylation. Electrons carried by NADH + H+ and FADH2 are transferred to oxygen via a series of electron carriers, and ATPs are formed. Three ATPs are formed from each NADH + H+, and two ATPs are formed for each FADH2 in eukaryotes.
Why in cellular respiration the amount of ATP molecules produced formed can be either 34 or 36?
Electron transport from the molecules of NADH and FADH2 made from glycolysis, the transformation of pyruvate, and the Krebs cycle creates as many as 32 more ATP molecules. Therefore, a total of up to 36 molecules of ATP can be made from just one molecule of glucose in the process of cellular respiration.
What happens in the ETC in cellular respiration?
The electron transport chain is the last stage of the respiration pathway. It is the stage that produces the most ATP molecules. The electron transport chain is a collection of carrier proteins found on the inner membrane of mitochondria. NADH release the hydrogen ions and electrons into the transport chain.
How do you get 38 ATP from glucose?
If glucose is the respiratory substrate, then we get the net gain of 38 ATP molecules in aerobic respiration from one glucose molecule. ATP molecules are produced by substrate-level phosphorylation and oxidative phosphorylation in ETS by the oxidation of NADH and FADH2.
Does glycolysis produce 36 ATP?
In eukaryotic cells, the theoretical maximum yield of ATP generated per glucose is 36 to 38, depending on how the 2 NADH generated in the cytoplasm during glycolysis enter the mitochondria and whether the resulting yield is 2 or 3 ATP per NADH.
How do you calculate the number of ATP produced?
How many ATP are produced in anaerobic respiration?
Anaerobic respiration results in the production of 2 ATP molecules.
How many ATP is produced in glycolysis?
The total number of ATP produced in glycolysis is 4 from one glucose molecule. 2 molecules of ATP are utilised in the first half of glycolysis so there is a net gain of 2 ATP molecules in glycolysis. Additionally, 2 NADH molecules are also produced in glycolysis.
What is the end product of the electron transport chain?
The end products of electron transport are NAD+, FAD, water and protons. The protons end up outside the mitochondrial matrix because they are pumped across the cristal membrane using the free energy of electron transport. Electron transport and oxidative phosphorylation are summarized in the illustration below.
Why does the electron transport chain produce the most ATP?
Electron transport chain produces an electrochemical gradient, which facilitates the synthesis of ATP by ATP synthase by chemiosmosis.
How many ATP are produced from the 10 NADH that enters the electron transport chain quizlet?
What comes out? A total of 10 NADH and 2 FADH2 enter the chain to drop off their electrons and H+. 34 ATP are produced.
What are the electron acceptors in cellular respiration?
Explanation: In cellular respiration, oxygen is the final electron acceptor. Oxygen accepts the electrons after they have passed through the electron transport chain and ATPase, the enzyme responsible for creating high-energy ATP molecules.
What are the 3 stages of cellular respiration?
Summary: the three stages of Aerobic Respiration Carbohydrates are broken down using all three stages of respiration (glycolysis, citric acid cycle and the electron transport chain).
