In order to function efficiently, enzymes need to be at an ideal pH and temperature.
Different enzymes have different ideal pH and temperature conditions. If the pH or
temperature is extreme for a particular enzyme, it can even denature an enzyme,
which can prevent it from binding and acting on its substrate. For the following two
scenarios, name the variable (temperature or pH) that is affecting the function of the
enzyme.
A) ATP is produced by cellular respiration in your human body cells. There are a variety of enzymes that work to produce
ATP, but one of those enzymes is called phosphofructokinase-1. This enzyme is sensitive to blood acidity. Blood can
become more acidic if a patient is in respiratory distress.

B) A popular lab that can be performed by students
is to test the reaction rate of catalase enzyme when
it acts on the substrate hydrogen peroxide. Catalase
has the ability to break down hydrogen peroxide.
Catalase can be found in beef liver from the grocery
store! However, if the beef liver is boiled first, the
catalase will not be able to break down hydrogen
peroxide.
