Enzyme Function and Properties

The video tutorial explains the role of enzymes and proteins, highlighting that proteins are chains of amino acids and enzymes are a type of protein. It discusses the structure of proteins, including primary structures and hydrogen bonding. The specificity of enzymes to substrates is emphasized, explaining how enzymes facilitate chemical reactions by forming enzyme-substrate complexes. The tutorial also covers how enzymes can either break down or combine substrates to form products. Finally, it explains the concept of catalysis, showing how enzymes lower the energy required for reactions, making processes faster and more efficient.

What are the building blocks of proteins?

• Monosaccharides

• Nucleotides

• Amino acids

• Fatty acids

Which statement is true about enzymes and proteins?

• All proteins are enzymes.

• Enzymes are not related to proteins.

• All enzymes are proteins.

• Proteins are not made of amino acids.

What type of bond is primarily responsible for the interaction between amino acid chains?

• Ionic bonds

• Metallic bonds

• Covalent bonds

• Hydrogen bonds

What is the role of the enzyme's active site?

• To change the enzyme's shape

• To specifically bind with its substrate

• To store energy

• To bind with any molecule

What happens when an enzyme and substrate form a complex?

• The substrate becomes inactive

• The enzyme is permanently altered

• A chemical reaction is facilitated

• The substrate is destroyed

How do enzymes affect chemical reactions?

• They stop the reaction

• They increase the energy required

• They slow down the reaction

• They lower the energy required

What is the result of an enzyme-catalyzed reaction?

• The reaction does not occur

• The products are formed more quickly

• The products are formed more slowly

• The reactants remain unchanged

What is the term for the energy required to start a reaction?

• Activation energy

• Potential energy

• Kinetic energy

• Thermal energy

What is the primary function of enzymes in the body?

• To transport oxygen

• To provide structural support

• To store genetic information

• To catalyze biochemical reactions

What would happen to a reaction without an enzyme?

• It would require less energy

• It would not occur at all

• It would proceed faster

• It would require more energy
