BiologyEnzymesASOCR Created by: JemmaVenessCreated on: 19-05-16 16:00 What are the 4 factors affecting enzyme activity Temperature, pH, enzyme concentration, substrate concentration 1 of 5 Explain temperatures effect on enzyme activity Rise in temperature makes the enzymes vibrate more. At a certain point, bonds break and enzymes denature so don't fit into active site 2 of 5 Explain pH effect on enzyme activity Enzymes also have an optimum pH that they work best at, 7. 3 of 5 Explain enzyme concentration effect on enzyme activity Increasing the concentration of enzymes increases the rate of reaction 4 of 5 Explain Substrate concentration effect on enzyme activity Higher the substrate concentration the faster the reaction 5 of 5
