10 Questions
What are enzymes primarily made of?
Proteins
Describe the structure of an enzyme.
Primary, secondary, and tertiary structure
What is the active site of an enzyme?
A crevice or pocket where the substrate fits
How do enzyme catalysts differ from inorganic catalysts?
Enzymes get damaged at high temperatures, unlike inorganic catalysts
Why are enzymes isolated from thermophilic organisms more thermally stable?
Because they are adapted to high temperatures
What is the difference between a physical change and a chemical reaction?
A physical change involves changes in shape without breaking bonds, while a chemical reaction involves breaking and forming bonds.
Explain the role of enzymes in accelerating chemical reactions.
Enzymes act as catalysts, increasing the rate of chemical reactions by lowering the activation energy required.
What is a metabolic pathway and how is it related to enzymes?
A metabolic pathway is a series of enzyme-catalyzed reactions that convert one compound into another. Enzymes play a crucial role in facilitating each step of the pathway.
How does temperature affect the rate of physical and chemical processes?
Temperature influences the rate of processes; generally, a 10°C increase doubles the rate, while a 10°C decrease halves it.
Give an example of an enzyme-catalyzed reaction and explain the impact of the enzyme on the reaction rate.
The reaction of CO2 + H2O catalyzed by carbonic anhydrase results in the formation of carbonic acid. The enzyme accelerates the reaction by about 10 million times.
