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. they are inorganic molecules.

Explanation:

• Most enzymes are proteins, though some are RNA - based (ribozymes). But the statement "They are proteins" is still a common characteristic.
• Enzymes have an active - site where they bind to specific substrates to catalyze reactions.
• Enzymes act as biological catalysts, increasing the rate of chemical reactions in living organisms.
• Enzymes are not used up during the reaction; they can be reused.
• Enzymes are organic molecules, not inorganic.

Answer:

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