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

Option (B).

Explanation:

Enzymes are the biocatalyst that has the ability to increase the rate of the biochemical reactions. They works at the specific biological temperature and pH conditions.

Different enzymes are used in different biochemical reactions. Enzymes are specific to its substrate shape. The enzymes has the shape according to its substrate. Some enzymes modify the shape of the substrate after its binding with substrate. All enzymes do not have the same shape as their substrate.

Thus, the correct answer is option (B).

gold i'm pretty sure i might be wrong

a researcher conducts an experiment on the secretion of a particular hormone in mice. scientists inject mice with a substance that stimulates the production of the hormone. the scientists then test the levels of hormones produced by the mice. the tool used to measure the hormones consistently detects the levels at 10 points lower than the actual hormone levels in the mice. this tool makes measurements, but the measurements aren't .
