Document Summary
Metabolism is the sum of all chemical reactions in the cell which is then divided into two parts known as. Catabolism breaking down large molecules into smaller ones. Synthesis of complex organic molecules from simpler ones. These redox reactions occur in electron transport chain (etc) Results of metablosim mircobial cells can do work. Transport work- take up nutrients, elimination of wastes, and maintenance of ion balances. Mechanical work- cell motility and movement of structures within cells: the laws of thermodynamics. Thermodynamics- a science that analyses energy changes in a collection of matter called a system called the surroundings. Energy can be either created nor destroyed. However, energy may be redistributed either within a system or between the system and its surroundings. Entropy amount of disorder in a system. Greater the disorder of a system, greater its entropy. Physical and chemical processes proceed in a way that randomness or disorder of the universe increases.
