Biology STAAR Review Biomolecules

Enzymes will...

• stop the reaction after the activation energy is used

• not affect activation energy needed and start a reaction

• lower activation energy needed and speed up reaction

• increase activation energy needed and speed up reaction

This can cause an enzyme to be denatured (no longer working)

• high temperature only

• change in pH level only

• high temperature, change in pH level, inhibitors

• inhibitors only

The chart shows that Enzyme K

• is not as effective as enzyme A

• is most effective at 70-75 degrees

• is most effective at 40-45 degrees

• requires more activation energy

Label A indicates the

• enzyme that speeds up the reaction

• substrate that is being eaten

• activation site where the enzyme and substrate meet

• pH level that might denature the enzyme

• Insulation, Cell Membrane and Energy Storage

• Quick Energy and plant cell walls

• Build tissue (muscle), hair and nails
