How many ATP molecules are produced by the electron transport chain?

Electron transport chain This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle). The electron transport chain takes place in the mitochondria. This stage converts the NADH into ATP.

Does the electron transport chain produce 32 ATP?

Under aerobic conditions, pyruvate can diffuse into mitochondria, where it enters the citric acid cycle and generates reducing equivalents in the form of NADH and FADH2. These reducing equivalents then enter the electron transport chain, leading to the production of 32 ATP per molecule of glucose.

How ATP is 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 36 ATP is produced?

During respiration, 36 ATP molecules are produced per glucose molecule. 2 molecules of ATP are produced outside mitochondria i.e., during glycolysis and other 34 molecules of ATP are produced inside mitochondria from Krebs cycle.

What is complex 4 in the electron transport chain?

Complex IV of the electron transport chain, also known as cytochrome c oxidase, is a multiunit structure that functions to transfer electrons form cytochrome c to oxygen and in the process form water and help generate a proton gradient. ... CuB associates with heme A-3 to help reduce oxygen into water.

How is 38 ATP formed?

Most of the ATP produced by aerobic cellular respiration is made by oxidative phosphorylation. ... Biology textbooks often state that 38 ATP molecules can be made per oxidized glucose molecule during cellular respiration (2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system).

How many ATP are generated in the electron transport chain quizlet?

How many ATP are produced in the electron transport chain? 36 ATP are generated in the electron transport chain.

What is the maximum number of ATP molecules that can be produced during the electron transport stage of aerobic respiration?

During electron transport, energy from NADH and FADH₂ is used to make many more molecules of ATP. In all three stages of aerobic respiration, up to 38 molecules of ATP may be produced from a single molecule of glucose.

How many ATP are produced in Calvin cycle?

In summary, it takes six turns of the Calvin cycle to fix six carbon atoms from CO₂. These six turns require energy input from 12 ATP molecules and 12 NADPH molecules in the reduction step and 6 ATP molecules in the regeneration step.

Why is ATP 38 or 36?

In many human cells, two NADH+H+ molecules are transformed to FADH2 during this transport, thus giving 2 fewer ATP molecules at the end (36 rather than 38). In bacterial cells, there are no mitochondria. In fact, its entire cell acts as the mitochondria.

Why is the total count about 36 or 38?

33. Why is the total count about 36 or 38 ATP molecules rather than a specific number? Since phosphorylation and the redox reactions aren't directly coupled to each other, the ratio of the number of NADH molecules to the number of ATP molecules is not a whole number.

How do we get 32 ATP?

In a eukaryotic cell, the process of cellular respiration can metabolize one molecule of glucose into 30 to 32 ATP. The process of glycolysis only produces two ATP, while all the rest are produced during the electron transport chain.

How many ATP are produced in glycolysis?

During glycolysis, glucose ultimately breaks down into pyruvate and energy; a total of 2 ATP is derived in the process (Glucose + 2 NAD+ + 2 ADP + 2 Pi --> 2 Pyruvate + 2 NADH + 2 H+ + 2 ATP + 2 H2O). The hydroxyl groups allow for phosphorylation. The specific form of glucose used in glycolysis is glucose 6-phosphate.

How many electron transport chains are there in a mitochondria?

The respiratory chain of mammalian mitochondria is an assembly of more than 20 discrete carriers of electrons that are mainly grouped into several multi-polypeptide complexes (Figure 5.1). Three of these complexes (I, III and IV) act as oxidation–reduction-driven proton pumps.

What is complex 3 electron transport chain?

Complex III of the electron transport chain, also known as Q-cytochrome c oxidoreductase or simply cytochrome reductase, is a multi-subunit structure that functions to accept electrons from ubiquinol and transfer them onto another electron carrier called cytochrome c.

How many ATP are produced in aerobic respiration 10?

A total of 36 ATPs are produced from aerobic respiration for each glucose that enters glycolysis (2 from glycolysis, 2 from citric acid cycle, 32 from ETP).

How many ATP are produced from 1 NADH?

In cytoplasm, one molecule of NADH is equivalent to 2 ATP. Inside the mitochondria, one molecule of NADH is equivalent to 3 ATP.

How many ATP are produced from the 10 NADH that enter the electron transport chain?

What about the FADH2? It donates its electrons at a slightly later step in the electron transport chain, so only two ATPs are produce for every FADH2 molecule. In a perfect world, the ten NADHs (10 x 3 ATPs) and two FADH2 (2 x 2 ATPs) molecules produced by the breakdown of each glucose molecule would yield 34 ATPs.
