Question

ribose
atp is an abbreviation for adenosine triphosphate, a complex molecule that contains
the nucleoside adenosine and a tail consisting of three phosphates. it is the energy
currency of the cell. atp is used by organisms as energy...the energy needed to
move, grow, digest, and all other processes that require energy.
which statements regarding the atp - adp cycle are true? (choose 3)
a atp synthesis takes place in the mitochondria of eukaryotic
cells.

b atp is regenerated from adp through the process of
phosphorylation.

c 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.

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

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

Explanation:

• A: Mitochondria are the main site of ATP synthesis via cellular respiration in eukaryotes.
• B: Phosphorylation (adding a phosphate group to ADP) regenerates ATP.
• C: High-energy bonds between phosphate groups store energy, with the 2nd-3rd bond having the most energy.
• D: Energy in ATP is stored in phosphate bonds, not adenosine manufacture.
• E: Ribose is not a direct product of photosynthesis (glucose is primary).

Answer:

A. ATP synthesis takes place in the mitochondria of eukaryotic cells, B. ATP is regenerated from ADP through the process of phosphorylation, C. 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.
