Question

what do we call this type of reaction that converts adp into atp?
photosynthetic
oxidative
phosphorylation

Explanation:

To determine the reaction converting ADP to ATP, we analyze each option:

• "Photosynthetic" relates to photosynthesis (converting light to chemical energy), but the specific reaction for ADP→ATP in energy metabolism is not just called photosynthetic.
• "Oxidative" is part of oxidative phosphorylation (a type of phosphorylation), but the general term for adding a phosphate to ADP (to make ATP) is phosphorylation.
• "Phosphorylation" is the process of adding a phosphate group. ADP (adenosine diphosphate) becomes ATP (adenosine triphosphate) when a phosphate group is added, so this reaction is phosphorylation (specifically, substrate - level or oxidative phosphorylation in different contexts, but the general term for ADP→ATP via phosphate addition is phosphorylation).

Answer:

phosphorylation
