NGSS.HS-PS1-4

The area that the substrate fits into on the enzyme is called the:

• Active Site
• Allosteric Site
• DiSulphide Bridge
• β-Pleated Sheet

At high temperatures enzyme activity declines because of:

• Denaturation
• Decreased Kinetic Motion
• Increased H-Bonding
• Dissociation of Ionic Compounds

Some bacteria live in hot springs. Their cells contain enzymes that function best at temperatures of 70 °C or higher. At the temperature of 50 °C, how will the enzymes in these bacterial cells most likely be affected?

• The enzymes will be destroyed by lysosomes
• The enzymes will lose their bond structure and fall apart.
• The enzymes will require less energy to function than at 70 °C.
• The enzymes will not increase the rate of reactions as much as they would at 70 °C. 

Enzymes are what macromolecule?

• Nucleic Acid

• Lipid

• Protein

• Carbohydrate

C is the

• substrate

• enzyme-substrate complex

• products

B is the

• substrate

• enzyme-substrate complex

• products

An enzyme ________ the activation energy needed for a reaction to occur.

• decreases

• increases

• does nothing to

• increases then decreases
