Q

Why are catalysts important?

A

they are important because they speed up and cause the chemical reaction to require less energy. without catalysts, the chemical reactions would occur to slowly to sustain life

Q

How do enzymes work?

A

Enzymes take in a substrate; substrate binds with the active site; active site holds substrate in place to speed chemical reaction; when chemical reaction is done the products are let go

Q

How does pH affect an enzyme?

A

If an enzyme is not near its optimum pH, chemical reactions will slow and the enzyme will denature

Q

How does temperature affect an enzyme?

A

If an enzyme is not near its optimum temperature, chemical reactions will be slow. When temperatures increase too much, the enzyme will denature
