AB->A+B+energy Which best describes this reaction A.)it's an anabolic reaction B.)it's an endergonic reaction C.)It's a photosynthesis reaction D.) It's A catabolic reaction

The option that best describes the reaction is D (It's a catabolic reaction).

Explanation:

Both plants and animals use the chemical energy in food to carry out the activities that are necessary for living,for growth and reproduction. These are metabolic processes which are divided into:

--> Anabolic process and

--> Catabolic process.

The Catabolic process involves the BREAKDOWN of large molecules with the release of energy. From the question:

AB -> A+ B+ energy

A typical example of a catabolic process that occurs in the body is cellular respiration which is the source of energy for the many anabolic processes that occur in a living organism. During a catabolic process (respiration),

--> stored chemical energy is released for doing work;

--> heat energy is given off;

--> large organic molecules are broken down into simple molecules.
