EOC Review Warm-up Questions
1.Baby food manufacturers sometimes use proteases in their products. Proteases catalyze the breakdown of the proteins in these foods,
making digestion easier for infants.
Proteases are which of the following types of molecules?
A. enzymes
B. fatty acids
C. hormones
D. monosaccharides
2.Although there are a limited number of amino acids, many different types of proteins exist because the
A size of a given amino acid can vary.
B chemical composition of a given amino acid can vary.
C sequence and number of amino acids is different.
D same amino acid can have many different properties.
The graph below shows the rate of activity for the enzyme catalase at different temperatures. Catalase helps convert hydrogen peroxide to
oxygen and water. The rate of catalase activity is directly related to the percent increase in oxygen.
3.Based on the graph, which of the following conclusions can be made about the
functioning of catalase?
A. Catalase works best at 34°C.
B. Catalase is destroyed at 34°C.
C. Catalase cannot function at 51°C.
D. Catalase functions most efficiently at 51°C.
The diagram below shows the molecular structure of glucose.
4. Glucose is a simple carbohydrate that is important to living organisms.
a. Describe the primary function of glucose in cells. __________________________________________________
b. Simple sugars like glucose can be used to make larger organic molecules. Identify two larger molecules made from simple sugars.
_________________________________________________________________________________
c. Identify a specific cellular process that would be affected by a glucose shortage, and discuss the effects of the shortage on the process
you identified. ________________________________________________________________________
5. Which terms would most likely be included in the explanation of the production of starch in a potato?
