Cells are like tiny little factories. They convert amino acids in to sugars to provide energy. small molecules are assembled into polymers. In muliticelluar organisms many cells used exported chimcals in other parts of the organism.
An organisms metabolism transfers matter and engergy subjects to the law of thermodynamics
Metabolism is the emergent property of life that arises from orderly interactions between molecules. A metabolic pathway begins with a specific molecule, which is then altered in a series of defined steps, resulting in a certian product.
Forms of engergy
Energy is the capacity to cause change. kinetic engergy is engergy dealing with movement. thermal engery is associated with kinetic energy but it is the release or the in take of heat. Potential energy is how much energy an object has.
The laws of energy transformation
Thermodynamics is the study of energy transformation that occurs in a collection of matter. The first lawof thermodynamics, the energy of the universe consists of energy that can be transfered and transformed but itcan not be created or desroyed. The second law of Thermodynamics every energy transfer or transformation increases entropy of the universe.
