Two samples of a human enzyme were used in an experiment. Before use: • sample X was heated to $80\, ^\circ\text{C}$ and then allowed to cool to $37\, ^\circ\text{C}$, • sample Y was cooled to $0\, ^\circ\text{C}$ and then warmed to $37\, ^\circ\text{C}$. How will this change their activity?
- ASample X and sample Y are no longer active.
- BSample X and sample Y will be equally active.
- CSample X will be more active than sample Y.
- DSample Y will be more active than sample X.
