ENZYMES, CATALYST

ENZYMES
Q.        What are enzymes?
Ans:     An enzyme is a protein that is synthesized in living cell
and catalyzes or speeds up a thermodynamically possible reaction so that rate of reaction is competible with biochemical process essential for maintenance of a cell.
Q. In what way enzymes differ from chemical catalyst?
Ans:     Enzymes are invariably proteins. They are highly specific
for reactions and produce only expected products. They function within a moderate pH and temperature range.
Q.        How an enzyme loses its activity?
Ans:     Being a protein, an enzyme loses its activity if subjected

to agents like heat acids or bases, organic solvents or other conditions which denature protein.
