What role do the ATP molecules play in the protein synthesis process?
a) They provide energy
b) The convert energy into hereditary information
c) They absorb excess energy to prevent overheating
d) They increase the activation energy

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 increasing the time needed for the reaction to occur
b) by decreasing the amount of energy needed to complete the reaction
c) by making the reaction reversible
d) by changing the chemical products of the reaction

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 continues to increase the rate of the reaction.
b) The enzyme changes shape and can no longer speed up the reaction.
c) The enzyme is used up and the reaction stops.
d) The enzyme begins to decrease the rate of the reaction.

Which statement correctly describes one similarity and one difference between cellular respiration and photosynthesis?
a) CR and PS both involve water, CR uses sugar and PS produces sugar.
b) CR and PS both involve water, CR requires light, PS requires chemical energy.
c) CR uses sugar, PS produces sugar. Both use light to produce energy.
d) Both use light to produce energy, CR requires just light, PS also requires chemical energy.

Which statement best explains why cellular respiration in plants and other organisms is dependent on photosynthesis?
a) Photosynthesis provides the materials that fuel cellular respiration.
b) Photosynthesis absorbs materials that are catalyzed during cellular respiration.
c) Photosynthesis is one of the final steps in cellular respiration.
d) Photosynthesis absorbs excess energy produced by cellular respiration.

All living things must maintain homeostasis in order to survive. Which statement best describes one way humans maintain homeostasis?
a) Temperature is regulated by sweating.
b) Water content is regulated by giving off carbon dioxide.
c) Water content is regulated by sweating.
d) Temperature is regulated by giving off carbon dioxide.

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 osmosis.
b) Sodium and potassium ions move by facilitated diffusion, glucose moves by active transport.
c) Sodium and potassium ions move by active transport, glucose moves by facilitated diffusion.
d) Sodium and potassium ions move by active transport, glucose moves by osmosis
