What effect will boiling have on an enzyme's activity? decreased active site due to changed shape
increased active site due to changed shape
O
less substrate due to increased product formation
o
more product due to increased molecular movement

decreased active site due to changed shape.

Explanation:

With the rising temperature, chemical bonds between molecules of enzymes break resulting to alter the standard shape of enzymes. the active site no longer fits substrate molecules and thus the effect of enzymes decreases.
