Multiple Choice

What happens when the CO2 level from cellular respiration increases in the blood?

The blood pH decreases, leading to acidosis.

The body temperature decreases.

Oxygen levels in the blood increase significantly.

The blood pH increases, leading to alkalosis.

Verified step by step guidance

Understand that CO2 is a byproduct of cellular respiration and is transported in the blood primarily as bicarbonate ions (HCO3-).

Recognize that an increase in CO2 levels in the blood leads to the formation of carbonic acid (H2CO3) through the reaction: CO2 + H2O ⇌ H2CO3.

Realize that carbonic acid dissociates into hydrogen ions (H+) and bicarbonate ions (HCO3-), increasing the concentration of hydrogen ions in the blood.

Know that an increase in hydrogen ion concentration results in a decrease in blood pH, a condition known as acidosis.

Conclude that the increase in CO2 levels from cellular respiration leads to a decrease in blood pH, causing acidosis, rather than affecting body temperature or significantly increasing oxygen levels.
