what is respiration
release of energy from organic compounds
what is respiration
release of energy from organic compounds
what is respiration
release of energy from organic compounds
what is breathing
gas exchange in the lungs involving diffusion for co2 and o2
what is ventilation
muscular contraction that control inhaling and exhaling
what is aerobic respiration
e chemical
reactions in cells that use oxygen to break down
nutrient molecules to release energy
what is the word equation for aerobic respiration
glucose + oxygen → carbon dioxide + water
chemical equation for aerobic respiration
C6H12O6 + 6O2 → 6CO2 + 6H2O
what is anaerobic respiration
chemical
reactions in cells that break down nutrient
molecules to release energy without using
oxygen
does aerobic respiration release more energy than anaerobic
anaerobic respiration releases much
less energy per glucose molecule than aerobic
respiration
word equation for anaerobic respiration in yeast
glucose → alcohol + carbon dioxide
word equation for anaerobic respiration in muscles during exercise
glucose → lactic acid
chemical equation for anaerobic respiration in yeast
C6H12O6 → 2C2H5OH + 2CO2
what causes oxygen debt
lactic acid builds up in muscles and
blood during vigorous exercise causing an oxygen
debt
