Overlooking the impact of temperature and pH on enzyme activity
Failing to relate enzyme functions to metabolic pathways
FAQs
Question: What are enzymes? Answer: Enzymes are biological catalysts that speed up chemical reactions in living organisms without being consumed in the process.
Question: How do enzymes work? Answer: Enzymes work by binding to substrates at their active sites, forming an enzyme-substrate complex that lowers the activation energy needed for a reaction to occur.
