Instructions: Answer all questions to get your test result.
1) Which statement best describes the energy transformation that occurs in plant cell plastids?
A
Mitochondria transform light energy into chemical energy.
B
Chloroplasts transform chemical energy into electrochemical energy.
C
Mitochondria transform chemical energy into electromagnetic energy.
D
Chloroplasts transform light energy into chemical energy.
2) What role do the ATP molecules play in the protein synthesis process?
A
The convert energy into hereditary information
B
They provide energy
C
They absorb excess energy to prevent overheating
D
They increase the activation energy
3) Carbonic anhydrase is an enzyme involved in the reaction of carbon dioxide with water to form a molecule that dissolves well in the liquid part of blood. How does carbonic anhydrace affect this reaction?
A
by making the reaction reversible
B
by decreasing the amount of energy needed to complete the reaction
C
by changing the chemical products of the reaction
D
by increasing the time needed for the reaction to occur
4) The activity of an enzyme decreases sharply at 63 degrees Celsius. Which statement best describes what happens to the enzyme when the temperature of the reaction increases to 63 degrees?
A
The enzyme begins to decrease the rate of the reaction.
B
The enzyme is used up and the reaction stops.
C
The enzyme changes shape and can no longer speed up the reaction.
D
The enzyme continues to increase the rate of the reaction.
5) Which statement correctly describes one similarity and one difference between cellular respiration and photosynthesis?
A
CR uses sugar, PS produces sugar. Both use light to produce energy.
B
CR and PS both involve water, CR requires light, PS requires chemical energy.
C
Both use light to produce energy, CR requires just light, PS also requires chemical energy.
D
CR and PS both involve water, CR uses sugar and PS produces sugar.
6) Which statement best explains why cellular respiration in plants and other organisms is dependent on photosynthesis?
A
Photosynthesis is one of the final steps in cellular respiration.
B
Photosynthesis provides the materials that fuel cellular respiration.
C
Photosynthesis absorbs excess energy produced by cellular respiration.
D
Photosynthesis absorbs materials that are catalyzed during cellular respiration.
7) All living things must maintain homeostasis in order to survive. Which statement best describes one way humans maintain homeostasis?
A
Water content is regulated by giving off carbon dioxide.
B
Water content is regulated by sweating.
C
Temperature is regulated by sweating.
D
Temperature is regulated by giving off carbon dioxide.
8) A sodium-potassium pump within a cell membrane requires energy to move sodium and potassium ions into or out of a cell. The movement of glucose in or out of a cell does not require energy. Which best describes the movement of these materials?
A
Sodium and potassium ions move by facilitated diffusion, glucose moves by active transport.
B
Sodium and potassium ions move by active transport, glucose moves by facilitated diffusion.
C
Sodium and potassium ions move by facilitated diffusion, glucose moves by osmosis.
D
Sodium and potassium ions move by active transport, glucose moves by osmosis
9) If an animal cell is placed in distilled water, it will swell and burst. The bursting of the cell is the result of which biological process?
A
osmosis
B
enzyme activity
C
respiration
D
active transport
