Carbon Compounds - Enzymes

Question 1

enzymes

Answer 1

• proteins that act as biological catalysts

- speed up chemical reactions

Question 2

active site

Answer 2

• where reactants can be brought together to react

- sites greatly reduce the energy needed for the reaction

Question 3

substrates

Answer 3

• the reactants of the enzyme-catalyzed reaction
• bind to active sites located on the enzyme
• the substrates and active site fit together like a LOCK and KEY

Question 4

activation energy

Answer 4

• energy that is needed to get a reaction started

- the energy that we require to start reactions comes from the breakdown of the food we eat
