The human body needs at least 1.03 x 10-^2 mol O2 every minute. If all of this oxygen is used for the

cellular respiration reaction that breaks down glucose, how many grams of glucose does the human body

consume each minute?

0.3093 g of glucose are consumed each minute by the body.

Explanation: During cellular respiration glucose is broken down in presence of oxygen to yield energy, water and carbon dioxide. The equation for the reaction taking place during cellular respiration is;

C₆H₁₂O₆ + 6O₂ → 6H₂O + 6CO₂

We are required to calculate the amount of glucose in grams;

Step 1: Calculate the moles of glucose broken down

From the equation, the mole ratio of glucose to Oxygen is 1 : 6

Moles of Oxygen in a minute is 1.03 * 10^-2 moles

Therefore, moles of glucose will be;

= (1.03 * 10^-2) : 6

= 1.717 * 10^-3 moles

Step 2: Mass of glucose

Mass is given by multiplying the number of moles with molar mass

mass = moles * molar mass

Molar mass glucose is 180.156 g/mol

Therefore;

Mass = 1.717 * 10^-3 * 180.156 g/mol

= 0.3093 g

Hence, 0.3093 g of glucose are consumed each minute by the body.
