How does ATP synthase work?

How does ATP synthase work?

ATP synthase is a complex which makes use of the proton potential created by the action of the electron transport chain in mitochondria. It transports a proton down the gradient and uses the energy to complete the phosphorylation of ADP to ATP.

What kind of protein is ATP synthase?

The mitochondrial ATP synthase is a multi-subunit protein complex having an approximate molecular weight of 550 kDa. The human mitochondrial ATP synthase or F1/F0 ATPase or complex V (EC 3.6. 3.14) is the fifth component of oxidative phosphorylation chain [12].

Is ATP synthase a channel protein?

It is an ion channel, because it funnels protons into the mitochondrion during ATP generation (Source: Davidson College). ATP synthase is composed of two subunits, F0 and F1. The 0 subunit is embedded in the inner membrane, and the other, containing the catalytic parts, protrudes into the matrix.

How do proteins move through ATP synthase?

During electron transport, the participating protein complexes push protons from the matrix out to the intermembrane space. The energy released pumps hydrogen out of the matrix space. The gradient created by this drives hydrogen back through the membrane, through ATP synthase.

What is the function of ATP synthase in the electron transport chain?

During electron transport, the participating protein complexes push protons from the matrix out to the intermembrane space. This creates a concentration gradient of protons that another protein complex, called ATP synthase, uses to power synthesis of the energy carrier molecule ATP (Figure 2).

Is ATP synthase a protein?

ATP synthase consists of two well defined protein entities: the F1 sector, a soluble portion situated in the mitochondrial matrix, and the Fo sector, bound to the inner mitochondrial membrane. F1 is composed of three copies of each of subunits α and β, and one each of subunits γ, δ and ε.

How does ATP synthase produce ATP quizlet?

How does ATP synthase produce ATP? Atp synthase allows H+ ions to pass thru the thylakoid membrane,and the Atp synthase rotates, creating the energy to bind Adp and a phosphate group to produce Atp.

What activates ATP synthase for ATP?

The ATP synthase (F1-ATPase) is attached to the Fo protein on the inside of the matrix. ATP synthase uses the protons flowing into the matrix to bind ADP and Pi and release ATP. The F1-ATPase is named by the reverse reaction it catalyzes when it is isolated from mitochondria and thus uncoupled from the proton gradient.

What is the role of ATP synthase quizlet?

ATP synthase is the enzyme that makes ATP by chemiosmosis. It allows protons to pass through the membrane using the kinetic energy to phosphorylate ADP making ATP. The generation of ATP by chemiosmosis occurs in chloroplasts and mitochondria as well as in some bacteria.

Which of the following describes the function of ATP synthase *?

Explanation: ATP synthase catalyzes the reaction that shows ADP and the phosphate group forming ATP. The hydrogen in the reactant side is the one involved in the proton gradient, and water is a byproduct of the reaction.

What is the role of ATP synthase in cellular respiration quizlet?

What is the role of ATP synthase in cellular respiration? ATP synthase is used to combine electrons with H+ ions and exygen to produse water and to convert ADP into ATP.
