question 22 of 22
how are enzymes and substrates related?
a. the enzyme and substrate are mirror images of each other.
b. the enzyme and substrate are identical.
c. the enzyme and substrate fit together like a lock and key.
d. the enzyme produces the substrate.

Explanation:

Enzymes are biological catalysts. The lock - and - key model explains the relationship between enzymes and substrates. In this model, the enzyme (lock) has a specific active site that fits the substrate (key) precisely. Enzymes and substrates are not mirror images (A is wrong), not identical (B is wrong), and enzymes do not produce substrates (D is wrong).

Answer:

C. The enzyme and substrate fit together like a lock and key.
