Where does the reaction ATP to ADP P occur?

Where does the reaction ATP to ADP P occur?

muscle contraction … ATP is broken down to ADP and phosphate (Pi); the reaction that occurs in the muscle, during which chemical free energy is converted into work, can be written as follows: ATP + H2O + contractile elements → ADP + P i + contractile elements + work + heat This equation…

Where do ADP and Pi come from?

This is done by a simple process, in which one of the 2phosphate molecules is broken off, therefore reducing the ATP from 3 phosphates to 2, forming ADP (Adenosine Diphosphate after removing one of the phosphates {Pi}). This is commonly written as ADP + Pi.

How does ATP turn into ADP P?

If a cell needs to spend energy to accomplish a task, the ATP molecule splits off one of its three phosphates, becoming ADP (Adenosine di-phosphate) + phosphate. The ATP molecule is just like a rechargeable battery. When it’s fully charged, it’s ATP. When it’s run down, it’s ADP.

Where is ADP produced?

platelet granules
Adenosine diphosphate (ADP) is a platelet activator that is released from platelet granules during the formation of a hemostatic plug.

What reaction is ADP 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.

What happens when ATP is converted to ADP?

When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP). This free energy can be transferred to other molecules to make unfavorable reactions in a cell favorable.

Where is ADP found in the cell?

ADP is stored in dense bodies inside blood platelets and is released upon platelet activation. ADP interacts with a family of ADP receptors found on platelets (P2Y1, P2Y12, and P2X1), which leads to platelet activation.

Where is the energy located in the ATP molecule indicate on your drawing in step 4 where the energy is being stored?

Where is the energy located in the ATP molecule? Within the bonds between the 3 phosphate groups.

What does the cell do with low energy ADP P?

When a phosphate breaks off, through chemical reactions in a cell, energy is released which the plant uses for cellular processes. The lower energy Adenosine DiPhosphate (ADP) is then re-energized during photosynthesis as the phosphate group is re-attached, thus completing the cycle of ATP to ADP to ATP…

Where does cellular respiration occur in mitochondria?

Mitochondria, organelles specialized to carry out aerobic respiration, contain an inner membrane folded into cristae, which form two separate compartments: the inner membrane space and the matrix. The Krebs Cycle takes place in the matrix.

What is the relationship between ADP and ATP?

ATP stands for adenosine triphosphate which is the energy currency of the cell while ADP stands for adenosine diphosphate. The difference primarily between the two is the number of phosphate groups in the molecule.

What turns ADP into ATP?

ADP is turned into ATP when electrons produced during light reaction of photosynthesis are absorbed by it.

How do you convert ADP to ATP?

Chemical Equation. The conversion of ADP to ATP can be written as ADP + Pi + energy → ATP or, in English, adenosine diphosphate plus inorganic phosphate plus energy gives adenosine triphosphate.

How is ADP converted into ATP?

ADP is converted to ATP for the storing of energy by the addition of a high-energy phosphate group. The conversion takes place in the substance between the cell membrane and the nucleus, known as the cytoplasm, or in special energy producing structures called mitochondria.
