Enzymes 2

The video tutorial explains that enzymes are protein catalysts that facilitate chemical reactions by lowering activation energy. It describes the structure of enzymes, highlighting the active sites where substrates bind. The tutorial further explains the process of enzyme-catalyzed reactions, including the formation of the enzyme-substrate complex and the transition state, ultimately leading to the conversion of substrates into products.

What is the primary structure of an enzyme composed of?

• Nucleic acids

• Carbohydrates

• Amino acids

• Fatty acids

What are the pockets in an enzyme's structure called?

• Catalytic sites

• Binding sites

• Active sites

• Reaction sites

At what temperature do enzymes typically become defunct?

• Above 30 degrees Celsius

• Above 40 degrees Celsius

• Above 50 degrees Celsius

• Above 60 degrees Celsius

What is the term for the energy difference between the substrate and the transition state in a reaction?

• Thermal energy

• Activation energy

• Kinetic energy

• Potential energy

What happens to the substrate in the enzyme-substrate complex?

• It is expelled from the enzyme

• It is destroyed

• It is converted to a product

• It remains unchanged
