Chemical Reactions and Enzymes Assessment

Enzymes are proteins used to:

• Store energy
• Catalyze reactions
• Transport molecules
• Provide structural support

The substances produced in a chemical reaction are known as:

• Substrates
• Reactants
• Catalysts
• Products

In a chemical reaction, the substances that are converted are called:

• Products
• Catalysts
• Reactants
• Enzymes

A competitive inhibitor works by:

• Changing the shape of the active site
• Blocking the substrate from binding
• Increasing enzyme production
• Altering the enzyme's pH

The suffix commonly used at the end of enzyme names is:

• -ose
• -ase
• -in
• -ide

The amount of energy needed to start a reaction is called:

• Kinetic energy
• Potential energy
• Activation energy
• Free energy

All chemical reactions in living things require special protein molecules called:

• Hormones
• Antibodies
• Enzymes
• Neurotransmitters

Enzymes are considered ____________ that speed up reactions.

• Inhibitors
• Substrates
• Products
• Catalysts

The specific region on an enzyme where substrates bind is called the:

• Allosteric site
• Coenzyme site
• Active site
• Protein fold

Which of the following does NOT affect the rate at which enzymes work?

• Enzyme concentration
• Substrate concentration
• Enzyme color
• Temperature
