Which explains why enzymes can catalyze reactions in cells?

Enzymes lower the activation energy needed to perform a reaction

Enzymes increase the temperature to allow reactions to happen.

Which statement is not regarding enzymes?

Any enzyme can work with many different types of substrate. It doesn't matter what it is.

They are made up of amino acids.

They remain unchanged in a chemical reaction (if the environment is ideal)

Which of the following is true of a denatured protein?

Its shape is changed and now it can no longer bind to the substrate to catalyze the reaction.

Its shape is now frozen in time with the substrate.

Any enzyme can work with many different types of substrate. It doesn't matter what it is.

Which statement is not true regarding Scientific Theories?

Theories do not have much data to support them.

Theories can change over time as we learn more and technology advances.

Theories are widely accepted and have lots of data to support them.

Theories can be tested just like a hypothesis.
