Energy and Metabolism. All living organisms need energy to grow and reproduce, maintain their structures, and respond to their environments. Metabolism is the set of life-sustaining chemical processes that enables organisms transform the chemical energy stored in molecules into energy that can be used for cellular processes.
These molecules are produced through various processes including cellular respiration and phosphorylation. ATP molecules are called the drivers of cellular metabolism. They carry the energy needed by a particular cellular activity. Another important thing about this molecule is that it is recyclable.t is a molecule found in the cells of living organisms. It is said to be very important because it transports the energy necessary for all cellular metabolic activities. It is dubbed as the universal unit of energy for living organisms. Without ATP, various metabolic activities in the human body cannot take place.
