Which tube showed the highest lipase activity in the described experiment?

Explanation:
Lipase works best when the reaction environment allows the enzyme to interact efficiently with its fat substrate. The fastest rate of triglyceride hydrolysis occurs when pH is near neutral, temperature is close to body temperature, and bile salts are present to emulsify fats and increase the surface area the enzyme can act on. The tube that showed the highest activity in the experiment is the one with these favorable conditions, which is why its readout changed (color or pH indicator) most rapidly. Tubes with suboptimal pH, temperature, or without bile would slow the reaction and show a slower change in the readout.
