Question

Proteins are biomolecules

a) What is denaturation of protein?

b) Match the following:

Vitamin A – Glucose

Starch – Zymase

Aldohexose – Night blindness

Enzyme – Amylose

– Fructose

Answer 1

a) When a protein in its native form is subjected to physical change like change in temperature or chemical change like change in pH, the hydrogen bonds are disturbed. Due to this, globules unfold and helix get uncoiled and protein loses its biological activity. This is called denaturation of protein.

b) VitaminA – Night blindness

Starch – Amylose

Aldohexose – Glucose

Enzyme – Zymase
