Front

What is an enzyme?

Back

A biological catalyst that speeds up chemical reactions in living organisms.

Front

What is the active site of an enzyme?

Back

The specific region on an enzyme where the substrate binds.

Front

What is a substrate?

Back

The reactant molecule that an enzyme acts upon.

Front

What are products in a chemical reaction?

Back

The substances that are produced as a result of a chemical reaction.

Front

What factors affect enzyme activity?

Back

Temperature and pH are the two main factors that affect enzyme operation.

Front

What is activation energy?

Back

The energy needed to initiate a chemical reaction.

Front

What does ATP stand for?

Back

Adenosine triphosphate, the energy currency of the cell.

Front

What does the 'TP' in ATP represent?

Back

Tri (3) phosphates.

Front

How do temperature and pH affect enzymes?

Back

Extreme temperatures and pH levels can denature enzymes, altering their shape and function.

Front

What is the role of ATP in cellular processes?

Back

ATP provides energy for various cellular activities, including muscle contraction and active transport.
