Best answer: What is the direct source of energy for ATP synthase to phosphorylate ADP?

In chemiosmosis, the most direct source of energy used to convert adp+pi to atp is through oxidative phosphorylation by energy released from movement of protons through atp synthase, down their concentration gradient.

What is the source of energy used by ATP synthase to convert ADP to ATP?

An enzyme called ATP synthase is embedded in the inner mitochondrial membrane. The protons diffuse through the ATP synthase, which uses the energy from the proton motive force to add a phosphate group to ADP molecules available in the matrix inside the inner membrane.

What is the direct source of energy for ATP synthase?

The electrons from from NADH and FADH2 flow through the electron transport chain in the inner mitochondrial membrane generating a H+ buildup in the inner membrane space. This proton gradient (gradient of H+) flowing through the membrane enzyme complex ATP synthetase is the direct energy source for producing ATP.

How does ATP synthase phosphorylate ADP?

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.

What are the steps of ATP synthesis?

In general, the main energy source for cellular metabolism is glucose, which is catabolized in the three subsequent processes—glycolysis, tricarboxylic acid cycle (TCA or Krebs cycle), and finally oxidative phosphorylation—to produce ATP.

How is ADP is converted to ATP?

ADP is combined with a phosphate to form ATP in the reaction ADP+Pi+free energy→ATP+H2O. The energy released from the hydrolysis of ATP into ADP is used to perform cellular work, usually by coupling the exergonic reaction of ATP hydrolysis with endergonic reactions.

Where is energy stored in ATP?

Adenosine Triphosphate

Energy is stored in the bonds joining the phosphate groups (yellow). The covalent bond holding the third phosphate group carries about 7,300 calories of energy. Food molecules are the $1,000 dollar bills of energy storage.

What is the most direct source of energy?

The substance which is the most direct source of the energy used by an animal cell for the synthesis of materials is Adenosine triphosphate (ATP). ATP, made up of an adenine nucleotide bound to three phosphates, is the molecular currency of transfer of energy within the cell.

What is the most direct source of energy to convert ADP to ATP?

In chemiosmosis, the most direct source of energy used to convert adp+pi to atp is through oxidative phosphorylation by energy released from movement of protons through atp synthase, down their concentration gradient.

What is the role of ATP synthase?

The function of ATP synthase is to synthesize ATP from ADP and inorganic phosphate (Pi) in the F1 sector. This is possible due to energy derived from a gradient of protons which cross the inner mitochondrial membrane from the intermembrane space into the matrix through the Fo portion of the enzyme.

What is the source of energy for ATP production?

The human body uses three types of molecules to yield the necessary energy to drive ATP synthesis: fats, proteins, and carbohydrates. Mitochondria are the main site for ATP synthesis in mammals, although some ATP is also synthesized in the cytoplasm.

What complex of ATP synthase is responsible for the synthesis of ATP?

Among those, Complex V (also known as the F1F ATP Synthase or ATPase) is responsible for the generation of ATP through phosphorylation of ADP by using electrochemical energy generated by proton gradient across the inner membrane of mitochondria.
