All living things require an outside source of materials and energy. The sum total of all chemical reactions that occur within a cell to provide these materials and energy is called metabolism.

Energy is the ability to perform work.  In an organism's body energy is required to perform each and every processes inside the body. In eukaryotic organisms this energy is derived by the mitochondria. In humans and various other species, the major source of energy is ATP.

Metabolism is the sum total of all the reactions taking place inside the body. These reactions can be anabolic or catabolic. The anabolic reaction involve the formation of larger molecules from the smaller ones. The catabolic reactions involve the breakdown of larger molecules into smaller ones.

Answer:

P. aeruginosa

Explanation:

<em>P. aeruginosa</em> is a gram-negative bacteria that belongs to the family Pseudomonadaceae.

From the given question the following points lead us to conclude that the colony that will be growing would be of P. aeruginosa :

1. Flat spreading colonies with a metallic sheen on SBA - <em>P. aeruginosa</em> is known to produce smooth colonies with flat edges.

2. Fluorescent green color in the media with clear colonies on cetrimide agar - <em>P. aeruginosa</em> is known to produce pyoverdin which is a fluorescent pigment under low iron conditions.

3. Medium clear colonies that have a "fruity or grape-like odor" on MacConkey Agar - <em>P. aeruginosa</em> has a sweet fruity odor which is its characteristic odor because of the production of trimethylamine.

Thus, from all these characteristics one can conclude that the organism in the culture is <em>P. aeruginosa. </em>
