AMOEBA SISTERS: VIDEO RECAP ENZYMES
Amoeba Sisters Video Recap: Enzymes
1. In the box below, please Illustrate an enzyme and
substrate. Label the following keywords in your
illustration: enzyme, substrate, and active site.
2. Enzymes are typically which type of bio molecule?
3. Describe the effects that enzymes can have on substrates.
Sukfrltate i<; kg|J K
In order to function efficiently, enzymes need to'be at an ideal pH ano 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 phosphofructokin ase-1. This enzyme is sensitive t o blood acidity. Blood can
become more acidic if a patient is in respiratory distress.
___________________________________________4. Variable affecting enzyme function:
5. Variable affecting enzyme function:
Bl A popular lab that can be performed by students
is t o test the reaction rate of catalase enzyme when
it acts o n the substrate hydrogen peroxide. Catalase
has the ability t o breakdown 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 b e able t o break down hydrogen
peroxide.
