Question

select the correct statement(s) that are valid characteristics of enzymes. enzymes are highly selective and will only work on one type of substrate. one type of enzyme can work on many different types of substrates. enzymes decrease biochemical reaction rates. enzymes are proteins. enzymes are made of carbohydrates. enzymes increase biochemical reaction rates.

Explanation:

Enzymes are highly specific in their action, usually working on one or a few types of substrates (not many different types). They are biological catalysts that increase biochemical reaction rates. Most enzymes are proteins, though some RNA - based enzymes (ribozymes) exist. They are not made of carbohydrates.

Answer:

Enzymes are highly selective and will only work on one type of substrate.
Enzymes are proteins.
Enzymes increase biochemical reaction rates.
