6.
A person is asked to run on a treadmill for two hours so data can be gathered on how lactic acid accumulates in the human body. Lactic acid is a product of anaerobic respiration. The results are placed in a table.
How did the respiration of the person change throughout the run?
a)
A. At the beginning of the run, the cells primarily performed aerobic respiration, but changed later in the run to perform more anaerobic respiration when the oxygen level decreased in the body.
b)
B. At the beginning of the run, the cells primarily performed anaerobic respiration, but changed later in the run to perform more aerobic respiration when the oxygen level increased in the body.
c)
C. At the beginning of the run, the cells primarily performed aerobic respiration, but changed later in the run to perform more anaerobic respiration when the oxygen level increased in the body.
d)
D. At the beginning of the run, the cells started with anaerobic respiration, but changed later in the run to perform more aerobic respiration when the oxygen level decreased in the body.
7.
Enzymes are proteins that help increase the rate of chemical reactions inside cells. These proteins are composed of many simpler molecules called amino acids. Which of the following suggests that the shape of an enzyme determines the enzyme’s function?
a)
A. Enzymes are specific to a substrate.
b)
B. Enzymes can operate in a wide range of conditions.
c)
C. Enzymes are activated by neighboring molecules
d)
D. Enzymes can be found in all life-forms.
8.
Pepsin and trypsin are two of the digestive enzymes that break down protein. A group of students studied the pH requirements of these enzymes. The graph below shows the results.
The students found that pepsin functions best in an acid environment and trypsin functions best in a neutral environment. Based on their observations, pepsin most likely aids in digestion in which part of the human body?
a)
Pancreas
b)
Intestines
c)
Mouth
d)
Stomach
