Questions and Answers

What is denaturation in the context of enzymes?

It is the process of enhancing the solubility of enzymes in water and salt solutions.
It is the process of breaking intra and inter-molecular non-covalent bonds, distorting the shape and active site of the enzymes. (correct)
It is the process of accelerating the reaction rates of enzymes without altering their structure.
It is the process of increasing the molecular weight of enzymes, affecting their catalytic activity.

What are the factors that can denature enzymes?

Low heat, stable pH, light metals, and low salt concentrations.
Low heat, alteration in pH, heavy metals, and high salt concentrations.
High heat, alteration in pH, heavy metals, and high salt concentrations. (correct)
High heat, stable pH, heavy metals, and low salt concentrations.

What is the property of enzymes that allows them to be dissolved in water and salt solutions?

Solubility (correct)
High molecular weight
Enzyme activity
Colloidal nature

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. Signup and view all the answers

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. Signup and view all the answers

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. Signup and view all the answers

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. Signup and view all the answers
