What is the biological significance of respiration to organisms?

• Respiration produces food for the organism

• Respiration creates energy for the organism

• Respiration releases energy from food

• Respiration consumes food

Respiration and burning of food are different because...

• Respiration requires oxygen, but not burning

• Respiration is multi-step, while burning is one-step

• Oxygen and water are produced in burning, but not respiration

• Heat energy is released in burning, but not respiration

Food is not broken down by burning in living cells because...

• More energy is released in respiration compared to burning

• Cells would be killed by the one-step release of energy

• No fuels are present in cells for burning to occur.

• Respiration requires less glucose for the release of energy
