is atp synthase an enzyme?
534334
ATP synthase is an enzyme that creates the energy storage molecule adenosine triphosphate (ATP), forming it from adenosine diphosphate (ADP) and inorganic phosphate (Pi). The overall reaction catalyzed by ATP synthase is: ADP + Pi + 3H+out ⇌ ATP + H2O + 3H.

What is absolutely required for this to operate? The electron transport chain will oxidize NADH and FADH, transferring the electrons to the carrier proteins in the ETC. This will create a proton gradiant which fuels ATP synthase to produce ATP molecules. THIS PROCESS REQUIRES OXYGEN!!

This type of phosphorylation involves the direct synthesis of ATP from ADP and a reactive intermediate, typically a high energy phosphate-containing molecule. Substrate level phosphorylation is a relatively minor contributor to the total synthesis of triphosphates by cells.

ATP synthase is one of the wonders of the molecular world. ATP synthase is an enzyme, a molecular motor, an ion pump, and another molecular motor all wrapped together in one amazing nanoscale machine. It plays an indispensable role in our cells, building most of the ATP that powers our cellular processes.

No ATP is produced in the electron transport chain. Is any ATP used in the electron transport chain? No, the electrons provide energy.

Substrate-level phosphorylation refers to the formation of ATP from ADP and a phosphorylated intermediate, rather than from ADP and inorganic phosphate, Pi, as is done in oxidative phosphorylation.

Adenosine triphosphate (ATP) is the energy molecule of the cell. During catabolic reactions, ATP is created and energy is stored until needed during anabolic reactions.

adenosine triphosphate …is produced by the enzyme ATP synthase, which converts ADP and phosphate to ATP. ATP synthase is located in the membrane of cellular structures called mitochondria; in plant cells, the enzyme also is found in chloroplasts.

ATP is a nucleotide that consists of three main structures: the nitrogenous base, adenine; the sugar, ribose; and a chain of three phosphate groups bound to ribose.

ATP Synthase Definition ATP synthase forms ATP from adenosine diphosphate (ADP) and an inorganic phosphate (Pi) through oxidative phosphorylation, which is a process in which enzymes oxidize nutrients to form ATP. ATP synthase is found in all lifeforms and powers all cellular activities.

ATP (adenosine triphosphate) has three phosphate groups that can be removed by hydrolysis to form ADP (adenosine diphosphate) or AMP (adenosine monophosphate). If there are no phosphates at all, the molecule is referred to as a "nucleoside", rather than a "nucleotide".

The process of substrate-level phosphorylation is conceptually simple. In practice, however, it is complex because specific individual chemical reactions must be catalyzed by specific individual enzymes to produce ATP.
1416663
The current research estimates that ATP synthase makes 1 ATP for every 4 H+ that pass through it, thus, the 10 H+ coming from the energy of one NADH would lead to the creation of 10/4 or 2.5 ATP.

All cells are able to synthesize ATP via the process of glycolysis. In many cells, if oxygen is not present, pyruvate is metabolized in a process called fermentation. Fermentation complements glycolysis and makes it possible for ATP to be continually produced in the absence of oxygen.

ATP when changed to a compound called adenosine diphosphate (ADP) releases energy for biological work in a cell. ... ATP is made up of smaller molecules or subunits-ribose, adenine, and phosphoric acid or phosphate groups. Ribose is a carbohydrate.

Adenosine triphosphate (ATP) is a nucleotide (nucleoside triphosphate) consisting of a nitrogen base (adenine), a sugar molecule (ribose) and a triphosphate group. ATP is the most important energy form for all organisms and can be said to be the cell's energy currency.

ATP Synthase. The ATP synthase is a mitochondrial enzyme localized in the inner membrane, where it catalyzes the synthesis of ATP from ADP and phosphate, driven by a flux of protons across a gradient generated by electron transfer from the proton chemically positive to the negative side.
