The lock an key analogy is used because each enzyme has specific substrates that fit into it. This is like how locks only work with a specific key. The enzyme is the lock and the substrates are the key.

This analogy is not perfect because there are often multiple substrates for each enzyme reaction. It only takes one key to turn the lock. The reaction is also taking place between the substrates themselves and not the enzyme. In the lock and key analogy, the lock is affected by the key, but in an enzyme reaction, the substrates are affected by the enzyme.
Hope I’ve helped ;)
Answer:
D
Explanation:
Prokaryotic are simple cells and do not have nucleus.
Mutations can occur before, during, and after mitosis and meiosis. If a mutation occurs in cells that will make gametes by meiosis or during meiosis itself, it can be passed on to offspring and contribute to genetic variability of the population
