Question

enzymes have which of the following characteristics? (select all that apply)
check all that apply
they are proteins.
they can bind with substrate.
they act as catalysts.
they are used up during the reaction

Explanation:

Enzymes are biological catalysts. Most enzymes are proteins (there are some RNA - based enzymes called ribozymes, but in general biology context, enzymes are considered proteins). Enzymes have an active site that can bind to a specific substrate. As catalysts, they speed up chemical reactions without being consumed in the reaction (so the statement “they are used up during the reaction” is incorrect).

Answer:

They are proteins, They can bind with substrate, They act as catalysts.
