Science

Which consequence decreases initial reaction rate in enzyme kinetics?

A)Competitive inhibitor binds active site
B)Substrate concentration greatly exceeds enzyme
C)Temperature reaches optimal point
D)pH buffers maintain optimal solution level

💡 Explanation

Competitive inhibition slows initial rate because the inhibitor occupies the enzyme's active site and prevents substrate binding, therefore diminishing complex formation, rather than allowing for increased or optimum process rates.
