Document Summary
Microbial metabolism: microbes play a major role globally in the cycling of elements (oxygen, carbon) in b. ecosystems. In some cases cycling reactions are performed only by microbes (ex. Nitrogen cycle: cells must do work c. i. Take up of nutrients, elimination of wastes and maintenance of ion balances c. iii. Cell motility and movement of structures within cells: metabolism is the total of all chemical reactions in the cell, divided into two parts: e. i. Typically, a large complex molecule broken down into smaller simple ones e. i. 3. The synthesis (building up) of large complex organic molecules from simpler ones e. ii. 2. Thermodynamics: a field that analyzes energy changes in a collection of matter called a system (e. g. a cell, calorie (cal) b. i. Amount of heat energy needed to raise 1 gram of water from 14. 5 to 15. 5 deg c c. Units of work capable of being done by a unit of energy c. ii.
