Is oxidative phosphorylation the same as etc?
The electron transport chain is a series of proteins and organic molecules found in the inner membrane of the mitochondria. Together, the electron transport chain and chemiosmosis make up oxidative phosphorylation.
Why is oxidative phosphorylation called so?
Potential energy In the mitochondrion, what the proton gradient does is facilitate the production of ATP from ADP and Pi. This process is known as oxidative phosphorylation, because the phosphorylation of ADP to ATP is dependent on the oxidative reactions occurring in the mitochondria.
Is oxidative phosphorylation the same as aerobic respiration?
You have just read about two pathways in glucose catabolism—glycolysis and the citric acid cycle—that generate ATP. The energy of the electrons is used to generate ATP. The entirety of this process is called oxidative phosphorylation.
What is the electron transport chain also known as?
The respiratory chain, otherwise known as the electron transport chain, resides in the mitochondria. The chain consists of a series of electron carriers which can accept and then donate electrons, while the resulting production of energy is used to stimulate the formation of ATP via oxidative phosphorylation.
What is the main function 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.
What process requires oxygen?
Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts.
Does the electron transport chain produce ATP?
The electron transport chain contains a number of electron carriers. These carriers take the electrons from NADH and FADH2, pass them down the chain of complexes and electron carriers, and ultimately produce ATP.
How many ATP are produced in oxidative phosphorylation?
28 ATP
How many ATP are used in the electron transport chain?
32 ATP
How 36 ATP is produced?
Electron transport system captures the energy of electrons to make ATP. Total ATP production from aerobic respiration: 36 ATPs for each glucose that enters glycolysis (2 from glycolysis, 2 from citric acid cycle, 32 from ETP).
Why is ATP 36 or 38?
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.
What are the steps of oxidative 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 …
What are the products of oxidative phosphorylation?
Overall, the process produces the 2 pyruvate plus 2 molecules of water, 2 ATP, 2 molecules of NADH, and 2 hydrogen ions (H+). The NADH carries electrons to the oxidative phosphorylation step of cellular respiration, which occurs inside of the mitochondrion.
What is the main function of oxidative phosphorylation?
Oxidative phosphorylation is the process in which ATP is formed as a result of the transfer of electrons from NADH or FADH 2 to O 2 by a series of electron carriers. This process, which takes place in mitochondria, is the major source of ATP in aerobic organisms (Figure 18.1).
Do all cells do oxidative phosphorylation?
Almost all aerobic organisms (organisms that require oxygen to live) use oxidative phosphorylation, in one way or another, to produce the basic energy currency of the cell needs to function: ATP (adenosine triphosphate).
Where does oxidative phosphorylation occur?
Oxidative phosphorylation takes place in the inner mitochondrial membrane, in contrast with most of the reactions of the citric acid cycle and fatty acid oxidation, which take place in the matrix.
Where does oxidative phosphorylation occur in bacteria?
The enzymes involved in electron transport and oxidative phosphorylation reside on the bacterial inner (cytoplasmic) membrane.
Where do prokaryotic cells perform oxidative phosphorylation?
plasma membrane
How many ATP do prokaryotes produce?
38 ATP
Why do prokaryotes produce more ATP?
Prokaryotes are simpler and do not have organelles. Thus, they carry out ATP production, using the same enzymes, which instead are tethered in their inner plasma membrane, i.e., the membrane that surrounds the entire cell.
What are the two main products of glycolysis?
1: Glycolysis produces 2 ATP, 2 NADH, and 2 pyruvate molecules: Glycolysis, or the aerobic catabolic breakdown of glucose, produces energy in the form of ATP, NADH, and pyruvate, which itself enters the citric acid cycle to produce more energy.
Is pyruvic acid a product of glycolysis?
Pyruvic acid is the end product of glycolysis.
What is the 3 carbon product of glycolysis?
Glycolysis, as the name suggests, is the process of lysing glucose into pyruvate. Since glucose is a six-carbon molecule and pyruvate is a three-carbon molecule, two molecules of pyruvate are produced for each molecule of glucose that enters glycolysis.
What are the 10 steps of glycolysis?
Glycolysis Explained in 10 Easy Steps

Is co2 used in glycolysis?
Glycolysis vs. The answer is C, carbon dioxide only. Glucose is a reactant of cellular respiration (and of glycolysis, the first step), while the others are intermediates along the way from deriving a total of 36 to 38 ATP from glucose so long as oxygen is present.
How much co2 is produced in glycolysis?
