AP Biology
Unit 3 – Cellular Energetics
Topic 3.3
How does the temperature affect enzyme reaction activity/rate of reaction and the way molecules move?
When temperature increases, fewer reactions occur due to the fastened movements of the substrates. Fastened movements create chaos in the cell and reduce the chances of pairing.
When temperature increases, more reactions occur due to the fastened movements of the substrates. This allows for more opportunities that the substrate may bump into the enzyme.
Any change in the temperature will denature the enzyme and stop it from functioning.
When temperature decreases, more reactions occur due to the slowing of the substrates, allowing it more precision to bind to the enzyme.
