TINUS ATP is an abbreviation for adenosine triphosphate, a complex molecule that contains t
phosphates. It is the energy currency of the cell. ATP is used by organisms as energy...th
that require energy.
Which statements regarding the ATP-ADP cycle are true?
ATP synthesis takes place in the mitochondria of eukaryotic cells.

The given question is incomplete as the group of choices are not given, however, the choices are associated with the question is given below:

ATP synthesis takes place in the mitochondria of eukaryotic cells.

ATP is regenerated from ADP through the process of phosphorylation.

energy is stored in the covalent bonds between phosphates, with the greatest amount of energy in the bond between the second and third phosphate groups.

most of the readily available energy stored in ATP is stored during the manufacture of adenosine.

the ribose sugar in the model above is the direct product of photosynthesis.

The correct answer is given below:

Explanation:

ATP synthesis takes place in the mitochondria cell organelle in the eukaryotic cells, however, a small part of ATP generation takes place in other cell regions but most of the ATP synthesis is occurs in the inner membrane of mitochondria which makes it energy house of the cell.

ATP is formed by the addition of phosphorus to ADP and this process is called phosphorylation.

Each bond of the adenosine and its three phosphates has stored energy in their covalent bonds. The last two phosphates have a high amount of energy in their bond.

the reason the two sea urchins don't compete with each other for food, resources, etc. is because the urchins have adapted to the environment but they have also adapted to each other. this is most likely because the genes of the sea urchins.
