10 Questions
What determines the equilibrium between S and P in the absence of the enzyme?
Ratio of the forward and reverse reaction rates
What effect does the enzyme have on the equilibrium between S and P?
Unaltered equilibrium state
What is the role of the transition state in enzyme-catalyzed reactions?
Facilitates conversion of substrate to product
How do enzymes increase the rate of reaction in both forward and reverse directions?
By reducing the activation energy
What characterizes the active site of an enzyme?
A specific region on the enzyme for substrate binding
What is the central role of enzymes as biological catalysts?
Increasing the rate of chemical reactions in cells
Why are most biological reactions catalyzed by proteins?
Proteins are more efficient than RNAs in catalyzing reactions
How do enzymes affect the rates of biochemical reactions?
They accelerate reaction rates without being consumed
What happens to biochemical reactions without enzymatic catalysis?
They would not occur under mild conditions of temperature and pressure
Why do cells contain thousands of different enzymes?
To determine which chemical reactions occur within the cell
Learn about how proteins act as enzymes, accelerating chemical reactions within cells. Understand why most biological reactions are catalyzed by proteins and the importance of enzymatic catalysis for maintaining life-sustaining processes.
