Multiple Choice Identify the choice that best completes the statement or answers the question.

• Which statement regarding the sodium–potassium pump is correct?
• The cell’s plasma membrane is more soluble to sodium ions than potassium ions.
• The concentration of sodium ions should be higher inside the cell compartment.
• The concentration of potassium ions should be higher outside the cell

compartment.

• The active transport involves pumping out three sodium ions and pumping in two

potassium ions.

• In the absence of oxygen, which cellular function creates the same amount of energy as is created in

the presence of oxygen?

• Dissipation of pyruvic acid
• Initiation of the citric acid cycle
• Activation of acetyl-coenzyme A
• Creation of acidosis via lactic acid

• Which option best supports the reason more energy is produced when a person is exercising?
• Exercise causes an increase in the synthesis of protein.
• There is an increase in the production of pyruvic acid in the cells.
• The conversion of pyruvic acid to lactic acid is increased by exercise.
• Muscle cells have more mitochondria to meet energy demands.
• When does ribosomal protein synthesis cease?
• During endoplasmic reticulum stress
• During the synthesis of adenosine triphosphate (ATP)
• During a severe hypoxic state
• During the processing of prohormone
• Which cellular organelles are responsible for propelling mucus and inhaled debris out of the lungs?
