10 Questions
What is denaturation in the context of enzymes?
It is the process of breaking intra and inter-molecular non-covalent bonds, distorting the shape and active site of the enzymes.
What are the factors that can denature enzymes?
High heat, alteration in pH, heavy metals, and high salt concentrations.
What is the property of enzymes that allows them to be dissolved in water and salt solutions?
Solubility
How do enzymes affect the reaction rates?
They accelerate the reaction rates.
What is not affected by the reaction catalyzed by enzymes?
The enzymes themselves
What are the physical properties of enzymes?
The physical properties of enzymes include denaturation, solubility, colloids, biocatalysts, precipitation, molecular weight, and enzyme activity.
What factors can denature enzymes?
Enzymes are denatured by high heat (above 40ºC), alternation in pH (too low or too high), heavy metals, high salt concentrations, solvents, and other reagents.
How does denaturation affect enzymes?
Denaturation is the process of breaking the intra and inter-molecular non-covalent bonds that distort the shape and active site of the enzymes, leading to loss of function.
What is the property of enzymes that allows them to be dissolved in water and salt solutions?
Solubility is the property of enzymes that allows them to be dissolved in water, salt (NaCl), diluted glycerol, and alcohol causing denaturation.
What is the effect of enzymes on reaction rates?
Enzymes accelerate the reaction rates without affecting the nature of products formed or undergoing any changes by the reaction catalyzed.
