Aerobic and Anaerobic respiration

• The two types of respiration are aerobic and anaerobic respiration
• Aerobic respiration = glucose + oxygen -> carbon dioxide + water + ATP (lots)
• Aerobic respiration uses oxygen so breaks down the entire glucose molecule and is more efficient than anaerobic respiration
• Anaerobic respiration = glucose -> ATP (little) + lactic acid
• anaerobic respiration doesn't use oxygen so doesn't full break down the entire glucose molecule, so is less efficent
• Anaerobic respiration produces lactic acid = a poisonous gas that causes cramps
• aerobic respiration occurs in mitochondria
• anaerobic respiration = less ATP made per glucose molecule
• aerobic respiration = more glucose made per glucose molecule
• respiration releases energy in the form of ATP
• Respiration reactions are controlled by enzymes (starch to glucose for respiration)
• Respiration also wastes energy in the form of heat
• heavy exercise = oxygen debt (body doesn't have enough oxygen) = lactic acid builds up = heavy breathing to repay debt (needed to break down lactic acid
• lactic acid = muscle cramps
• more fit = stronger hearts so can breath in more oxygen = pumped around more efficiently = more aerobic respiration = less lactic acid
• Less fit = produce less co2 (made in aerobic resp) + more lactic acid ; doing more anaerobic resp as they can't breathe in as much oxygen
