Question

Which of the following statements about enzymes is not true? (1 point)enzymes work best at a specified ph. all enzymes have the same shape as their substrates. enzymes are proteins. the shape of an enzyme allows it to do its job.

Answer 1

The answer is all enzymes have the same shape as their substrates.

The enzyme (which is basically a protein) does not have the same structure as its substrate, but has a structural cavity that allows the substrate to be recognized by the enzyme. So there is a correlation between structure and activity, and to maintain its structure, it needs a particular environment (pH, temperature ...).

Answer 2

The shape of an enzyme allows it to do its job as this would refer to the induced fit model. Where the enzymes active shape can change shape slightly, to bind completely to the substrate.
