Why is it important to understand the difference between breathing and respiration?
Answer and explanation
Correct answer: Because breathing is movement of gases and respiration is energy release in cells
Breathing is the physical exchange or movement of air: inhalation brings oxygen into the respiratory system and exhalation removes carbon dioxide. Respiration is a chemical process occurring in cells, in which glucose is broken down to release usable energy, usually with oxygen and sometimes without it. Breathing supplies gases needed for aerobic respiration, but the two terms are not identical. Hence option A is correct; the other choices confuse or restrict the processes incorrectly.
