What is the function of enzymes and how do temperature and pH affect their activity?
Understand the Problem
The question seems to relate to the function of enzymes, specifically how they interact with substrates and the effects of temperature and pH on this interaction. It likely involves explaining the induced fit model of enzyme action.
Answer
Enzymes catalyze reactions by lowering activation energy. Temperature and pH influence their activity, with high temperatures and extreme pH leading to denaturation.
Enzymes speed up reactions by lowering activation energy. Temperature increases kinetic energy, enhancing enzyme activity until denaturation occurs. Enzymes have optimal pH; deviations reduce activity.

More Information
Enzymes are crucial biological catalysts necessary for metabolic processes. They require specific conditions to function optimally and can be influenced by temperature and pH, which affect their structural integrity and activity.
Tips
Common mistakes include assuming higher temperature always increases enzyme activity; excessive temperatures denature them.
