NGSS.HS-LS2-5

The substance on which an enzyme acts is the -

• product

• substrate

• activation energy

• active site

Changing the shape (such as overheating) of an enzyme results in the enzyme's loss of -

• ability to catalyze a reaction

• storage of inherited information

• net electrical charge

• storage of a large amount of chemical energy

Refer to the figure above. What temperature would be considered the optimum temperature for this enzyme's activity rate?

• 20 Degrees Celsius

• 60 Degrees Celsius

• 40 Degrees Celsius

• 30 Degrees Celsius

What suffix is used in the names of most enzymes?

• -nic

• -ase

• -gen

• -yme

Both lipids and carbohydrates are important in animal cells because both -

• provide insulation

• store energy

• contain nitrogen

• form cell walls
