Which of the following statements correctly describes the concept of enzyme saturation in the context of acids and bases?
A
Enzyme saturation refers to the point at which the enzyme starts to denature due to high substrate concentration.
B
Enzyme saturation occurs when the enzyme is fully occupied by substrate molecules, and increasing substrate concentration does not increase the reaction rate.
C
Enzyme saturation is the condition where the enzyme activity is at its lowest due to lack of substrate.
D
Enzyme saturation is achieved when the enzyme concentration is equal to the substrate concentration.
Verified step by step guidance1
Understand the concept of enzyme saturation: Enzyme saturation refers to the condition where all active sites of the enzyme molecules are occupied by substrate molecules.
Recognize the relationship between enzyme saturation and reaction rate: When an enzyme is saturated, increasing the substrate concentration further does not increase the reaction rate because all active sites are already occupied.
Differentiate between enzyme saturation and enzyme denaturation: Enzyme saturation is not related to denaturation, which involves the loss of enzyme structure and function due to external factors like temperature or pH.
Identify the correct statement: The statement that correctly describes enzyme saturation is the one that mentions the enzyme being fully occupied by substrate molecules, and further increase in substrate concentration does not increase the reaction rate.
Clarify misconceptions: Enzyme saturation does not imply the enzyme activity is at its lowest due to lack of substrate, nor does it mean enzyme concentration is equal to substrate concentration.
