Question 1

Which equation best describes the relationship between pressure, volume, and temperature for gases and liquids in the human body?

Accepted Answer

$$P V = n R T$$

Question 2

During cellular respiration, which of the following is a direct product when glucose is metabolized with oxygen?

Accepted Answer

All of the above

Question 3

If the volume of the bladder decreases due to uterine expansion during pregnancy, what happens to the pressure on the bladder according to the ideal gas law?

Accepted Answer

Pressure increases

Question 4

Which of the following best explains why carbon dioxide ($$CO_2) is $$converted to bicarbonate ($$HCO_3$$^-$$) in the blood?

Accepted Answer

Bicarbonate moves more easily in water

Question 5

What is the main tradeoff when converting $$CO_2 to$$ $$HCO_3$$^-$$ in the blood?

Accepted Answer

It decreases blood pH, making it more acidic

Question 6

Which of the following reactions represents the conversion of carbon dioxide in water?

Accepted Answer

$$CO_2 + H_2O$$ \leftrightarrow H_2CO_3 \leftrightarrow $$HCO_3^- + H$$^+$$

Question 7

Which of the following is a correct statement about ATP in metabolic reactions?

Accepted Answer

ATP can be either a reactant or a product depending on the direction of the reaction

Question 8

A patient is unable to efficiently remove $$CO_2$$ from their blood. What is a likely consequence?

Accepted Answer

Blood becomes more acidic

Question 9

Which of the following best describes the role of oxygen in cellular respiration?

Accepted Answer

It is a reactant required to produce ATP

Question 10

If a person hyperventilates and expels too much $$CO_2$$, what is the likely effect on blood pH?

Accepted Answer

Blood pH increases (more basic)

Question 11

Which of the following is NOT a product of the complete aerobic breakdown of glucose?

Accepted Answer

Oxygen

Question 12

Why is it important to remove $$CO_2$$ from the body efficiently?

Accepted Answer

$$CO_2 is $$toxic at high concentrations

Question 13

Which of the following best illustrates the concept of physiological tradeoff discussed in the notes?

Accepted Answer

Increasing $$CO_2$$ removal also increases blood acidity

Question 14

If the amount of gas (n) in a closed system increases while temperature and volume remain constant, what happens to the pressure according to the ideal gas law?

Accepted Answer

Pressure increases

Question 15

Which of the following is a correct representation of the overall equation for aerobic cellular respiration?

Accepted Answer

$$C_6H_{12}O_6$ + 6 O_2$ \rightarrow 6 CO_2$ + 6 H_2O + ATP + heat$$
