• speeds up
• lowering
• activation energy
• slows down, raising, reaction rate
• blocks, increasing, substrate concentration
• inhibits, stabilizing, product formation

What happens when enzymes are heated to a high temperature?

• The enzyme no longer functions because it denatures

• Enzymes increase in size and mass.
• Enzymes remain unchanged and continue to function normally.
• Enzymes become more active and efficient.

A student makes a Venn Diagram to compare functions of carbohydrates and lipids. Which cellular function of carbohydrates and lipids should be placed in the shared section of the Venn Diagram? 

• Hormone production

• Structural support of the cell walls

• Energy storage

• Catalyst for chemical reactions

What is the optimal temperature for this enzyme?

Select all of the statements about enzymes that are true.

• Enzymes are destroyed when they are used and must be synthesized for each reaction

• Enzymes are made of protein

• Enzymes are specific because of their shape and catalyze only certain reactions

• Enzymes lower the activation energy of reactions
