What molecule add a phosphate group to ADP to make ATP?

What is needed to add a third phosphate group to ADP to make ATP?

ATP synthase


Where does the energy add a phosphate group to ADP to form ATP come from?

The energy needed to add a phosphate group to ADP to form ATP comes from cellular respiration, specifically the process of oxidative phosphorylation. During oxidative phosphorylation, energy is released as electrons move down the electron transport chain, which is used to pump protons across the inner mitochondrial membrane. The flow of protons back through ATP synthase drives the phosphorylation of ADP to form ATP.


What produces ATP by blinding phosphate groups to ADP?

ADP is exactly the same as ATP except that ATP has one more phosphate group. (ATP=Adenosine Triphosphate, ADP=Adenosine Diphosphate) This means that adding a phosphate group to ADP would make it ATP simply by definition.


How is ATP regenerated from ADP?

One molecule of ADP can be easily formed to make one form of ATP. All you need to do is add one phosphate group to the ADP and ATP is formed.ADP + P + energy --> ATPADP + P + energy --> ATP


Does oxygen and phosphate bond together to make ATP?

No, oxygen and phosphate do not directly combine to form ATP. ATP is produced through a series of chemical reactions in the mitochondria called cellular respiration, where oxygen is used as a reactant to help generate ATP from the breakdown of glucose or other energy sources.

ATP synthases produce the force need to add one what to each ADP molecule by spinning when hydrogen ions flow through them?

The electron gradient created by the electron transport chain flows from the inner membrane space to the matrix through the ATP synthase which captures energy from the proton motive force to create lots of ATP in oxadative phosphorylation.


Does making ADP From ATP require energy?

It requires energy. ADP is adenosine diphosphate and ATP is adenosone triphosphate. Basically, ATP has three phosphate groups (tri-phosphate) and ADP has two (di-phosphate). When ATP releases energy, a phosphate group is detached, forming energy and ADP. Therefore, to get ATP from ADP, energy is required to add one phosphate group onto the ADP.


What organic compounds or nutrients in main source of ATP?

ATP is manufactured in every aerobic cell by using energy from metabolizing sugars with oxygen to add a phosphate group to ADP. Anaerobic cells also produce ATP from a phosphate group and ADP, but the energy comes from reactions not involving oxygen (e.g. sulfur might be an option).


What is the name and function of the protein channel where hydrogen ions escape into the matrix of the mitochondrion?

The protein channel is called ATP synthase. It functions in the mitochondrion by allowing hydrogen ions to flow back into the matrix through the channel, which generates ATP in the process known as oxidative phosphorylation.


Why is it efficient to keep only a small supply of ATP on hand?

One molecule of sugar glucose can store 90x or more energy than is needed to add a phosphate group to ADP to make it ATP.
