7 Questions
What is the main function of enzymes in living organisms?
Speed up chemical reactions
What is the role of the substrate in the Lock and Key Model of enzyme action?
The molecules before they react, complementing the active site
How does an increase in temperature affect enzyme activity?
Increases collisions between molecules, enhancing reaction rates
What happens to an enzyme if the temperature is too high?
It loses its shape and no longer binds with substrates
How can a low temperature affect enzyme-catalyzed reactions?
Slow down reactions due to lack of kinetic energy
What effect does pH have on enzyme activity?
Can lead to denaturation of enzymes
What is meant by the term 'optimum temperature' for enzymes?
The temperature at which enzymes work best and have the fastest reaction rates
Test your knowledge on enzymes, specific proteins that act as biological catalysts to speed up chemical reactions in living organisms. Learn about the lock and key model and how enzymes lower the activation energy needed for reactions.
