How does the electron transport chain make ATP?

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.

How does electron transport chain make ATP?

How are electrons transported in the electron transport chain?

Electrons from electron carriers, such as NADH and FADH2, go through the electron transport chain, which involves a series of molecules that accept and donate electrons. The oxygen molecule accepts the electron from the final protein in the chain and becomes water, one of the final products of metabolism.

How many ATP can be made from each NADH during the electron transport process?

2.5 ATP
When electrons from NADH move through the transport chain, about 10 H +start superscript, plus, end superscript ions are pumped from the matrix to the intermembrane space, so each NADH yields about 2.5 ATP.

How many ATP does a glucose molecule produce during cellular respiration?

Cellular respiration produces 36 total ATP per molecule of glucose across three stages. Breaking the bonds between carbons in the glucose molecule releases energy. There are also high energy electrons captured in the form of 2 NADH (electron carriers) which will be utilized later in the electron transport chain.

How many ATPs are formed from 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 many ATPs are formed in oxidative phosphorylation?

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 is ATP 36 or 38?

How many ATP are produced in glycolysis and TCA cycle?

How many ATP are produced in glycolysis and TCA cycle? 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.
