Document Summary
Enzyme reduces energy required for reaction to occur. Many more reactions occurring at that same energy level. Reconfiguring the substrate, so when it collides with a compound, will be a better match of that substrate to the other reaction to give you that reaction. Energy level doesn"t change, just more reactions within it. Increase in temp increases energy level, causing reactions to occur faster. Cofactors and coenzymes bind to enzymes and facilitate the match between enzyme and other reactions to get product. Coenzymes are organic, cofactors are non protein. Phosphocreatine at beginning giving majority of atp. 100 m dash, males around 10 sec, females over 10 sec. Atp= high energy compound, can be used quickly. Conc. of pcr is 4-5x greater than atp. Little atp available for energy within the cell. Require different energy systems to replenish the atp pool. Atp pcr system"s greatest advantage is that with few reactions, pcr can be broken down and will form atp.
