Explanation:

1. ACTIVATORS are chemical mechanisms e.g protein, enzymes, that activate or start a reaction.

2. DEPHOSPHORYLATION is the process that occurs when a phosphate group is removed from a molecule; For example, when a phosphate from ATP is removed to make ADP and a free phosphate molecule (PO43-). i.e. ATP = ADP + Pi (inorganic phosphate).

3. INHIBITORS are those chemical mechanisms that prevent something, usually a chemical reaction, from occurring.

4. METABOLIC PATHWAYS are a chain of enzyme reactions within cells that break down (catabolic) or build (anabolic) molecules.

5. METABOLISM refers to all of the chemical reactions in an organism required for maintenance of the processes of life.

6. OXIDATION is a chemical reaction in which oxygen (O2) is combined with another substance.

7. PHOSPHORYLATION is a process that occurs when a phosphate is added to a molecule; For example, when a phosphate is added to ADP to make ATP. i.e. ADP + Pi = ATP

i think that d. wind is the answer.   i missed the question when i answered a. currents.
