Question

Which of these can be one of the uses of colloids?

• A. Colloids act as transport vector
• B. Colloids are used in intravenous therapy
• C. Movement of enzyme molecules in water is because of colloid action
• D. All of the above

Answer 1

The correct option is D All of the above

Colloid acts as a transport vector of different contaminants in water surfaces. For example, heavy metals and radionucleides are absorbed on colloid surface and are carried throughout the water
Enzymes, which are important biomolecules in human body, freely move about in the water because of colloid action.
Colloids are used in intravenous therapy where they increase the intravascular volume and maintain a high colloid osmotic pressure in the blood
