What are the products of the electron transport chain in cellular respiration?
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.
What does the ETC create?
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. The mechanism by which ATP is formed in the ETC is called chemiosmotic phosphorolation.
Where are electron transport chain proteins found?
mitochondria
The electron transport chain is located in the mitochondria. There are five main protein complexes in the ETC, located in the inner membrane of the mitochondria. These are labelled Complexes I, II, III, IV and V.
What 3 things are produced in the electron transport chain?
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.
How is ATP created in the electron transport chain?
The Electron Transport Chain. ATP is created when hydrogen ions are pumped into the inner space (lumen) of the thylakoid. Hydrogen ions have a positive charge. Like in magnets, the same charges repel, so the hydrogen ions want to get away from each other. They escape the thylakoid through a membrane protein called ATP synthase.
When is energy released from the electron transport chain?
Energy is released during cell metabolism when ATP is hydrolyzed. This happens when electrons are passed along the chain from protein complex to protein complex until they are donated to oxygen forming water.
Which is the electron carrier in cellular respiration?
The electron carrier of glycolysis is NAD+ (nicotinamide adenine diphosphate). Electrons are transferred to 2 NAD+ to produce two molecules of NADH. The energy stored in NADH is used in stage III of cellular respiration to make more ATP.
How many molecules of ATP are made in cellular respiration?
Electron transport from the molecules of NADH and FADH 2 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.
