Document Summary
Compare and contrast the difference/ explain catabolic and anabolic reactions. Identify and compare and contrast enzymes and enzyme functions. Be able to explain what occurs in an enzymatic reaction and what occurs if it is interrupted. This will lead right into cellular respiration and photosynthesis metabolism is. Sum of all chemical reactions of an organism. An emergent property of life > arises from orderly interaction between molecules metabolic pathways. A metabolic pathway begins with a speci c molecule and ends with a product. Each step is catalyzed by a speci c enzyme. Ex: cellular respiration= breakdown of glucose: anabolic pathways. Ex: synthesis of protein from amino acids forms of energy. Potential e= stored e > has not yet been used. Heat (thermal energy): random movement of atoms of molecules. Study of e transformation: first law of thermodynamics. Converted from one form to another: second law. Every e transfer or transformation increases the entropy (disorder) of the universe.
