Bio Starr

What's going on in this picture?

• The enzyme is taking the red substrate and turning it blue

• The enzyme's active site is blocked by a competitive inhibitor

• The enzyme can't function if too many substrates are trying to bind

• This is an example of an anabolic enzyme reaction

With what 3 letters do enzymes typically end?

• -ose

• -ase

• -ese

• -tic

Enzymes are an example of

• Lipids

• Carbohydrate

• Protein

• Nucleic Acid

Most chemical reactions in the body rely on enzymes. Why are enzymes are necessary for many cellular reactions?

• The reactions are too slow to meet the needs of the cell if enzymes are missing

• The reactions take up too much space in the cell if enzymes are missing

• Enzymes change reactants from solid to liquid during the reactions.

• Enzymes supply the oxygen necessary for the reactions.

The human body maintains a temperature of around 98.6 degrees at all times. Enzymes are involved in almost every chemical reaction in the body. Which of the following describes the connection between these two statements?

• The body is kept relatively warm to prevent too much enzyme action.

• The body needs to be warm to prevent hypothermia.

• Enzymes function best at a specific temperature.

• There is no connection between the two statements.

Any substance that is acted upon by an enzyme is called a(n)?

• Coenzyme

• Substrate

• Vitamin

• Polypeptide

What happens when enzymes are heated to a high temperature?

• The enzymes die.

• The shapes of the enzyme are altered denature

• The enzymes' amino acid sequence changes.

• The enzymes remain the same

How does an enzymes shape relate to its function?

• the shape of the enzyme has no relation to its function

• the enzyme is shaped specially for certain substrates to perform a specific reaction

• the enzyme shape acts as a receptor to certain products

• the enzyme shape can fit into specific substrates to cease a reaction

What is the primary role of enzymes in biological reactions?

• To increase the rate of reactions

• To decrease the rate of reactions

• To act as a reactant

• To act as a product

Which of the following is a characteristic of enzymes?

• They are consumed in the reaction

• They are specific to substrates

• They are made of carbohydrates

• They are inorganic molecules
