3318508792Factors that affect enzyme functionsEnzyme concentration, substrate concentration, temperature, pH, salinity, activators, inhibitors88
3318524701Enzyme concentration (enzymes)As enzyme increases, reaction rate increases, more enzyme =more frequently collide with substrate89
3318528136Enzyme concentration reaction rate levels offSubstrate becomes limiting factor, not all enzymes molecules can find substrate90
3318529892Substrate concentration (enzymes)As substrate increases, reaction rate increases, more substrate = more frequently collide with enzyme91
3318532519Substrate concentration reaction rate levels offall enzymes have active site engaged, all enzymes are saturated, max rate of reaction (only certain amount of active sites)92
3318535474Temperature (enzymes)Depending on the temperature, the enzyme is going to denature or the molecules will move slower93

3318542489Heat: increase beyond optimum temp (enzymes)Denatures- increased energy level of molecules disrupts bonds in enzyme and between enzyme and substrate95
3318548595Cold: decrease temp (enzymes)Molecules move slower, decrease collisions between enzyme and substrate96
3318550083pH (enzymes)Depending on the level of pH the enzyme will denature or not97

3318579839Noncompetitive inhibitions (enzymes)Inhibitor binds to site other than active site104
3318586314Irreversible inhibition (enzymes)Inhibitor permanently binds to enzyme105
