Most chemical reactions in the body rely on enzymes. Why are enzymes are necessary for many cellular reactions?

• The reactions are too slow to meet the needs of the cell if enzymes are missing

• The reactions take up too much space in the cell if enzymes are missing

• Enzymes change reactants from solid to liquid during the reactions.

• Enzymes supply the oxygen necessary for the reactions.

Any substance that is acted upon by an enzyme is called a(n)?

• Coenzyme

• Substrate

• Vitamin

• Polypeptide

Based on the graph, what is the optimal temperature for this enzyme? 

• 15^oC

• 40^oC

• 30^oC

• 35^oC

How does an enzymes shape relate to its function?

• the shape of the enzyme has no relation to its function

• the enzyme is shaped specially for certain substrates to perform a specific reaction

• the enzyme shape acts as a receptor to certain products

• the enzyme shape can fit into specific substrates to cease a reaction
