Anaerobic respiration in animals and plants and fungi 0.0 / 5 ? BiologyBiological molecules, organic chemistry and biochemistryA2/A-levelCCEA Created by: Football03Created on: 20-02-22 13:54 What happens to pyruvate in anaerobic respiration in animals? Pyruvate becomes reduced by the hydrogen ions from NADH2 to form lactate 1 of 11 Where does anaerobic respiration take place in mammals? In the skeletal muscles as a consequence of strenuous exercise 2 of 11 Why is it beneficial for mammals to be able to respire anaerobically (without O2)? Provides extra energy -Escape predators -Winning a 100m sprint 3 of 11 What happens before anaerobic respiration occurs within a mammal? -The animal will maximise ATP production from aerobic respiration -Increasing breathing and heart rate 4 of 11 What happens when lactate is produced in the muscles? Muscle fatigue and cramp 5 of 11 What is the lactate converted to ,for it to be removed when sufficient oxygen is available? Converted back to glucose 6 of 11 Why does the body need extra oxygen after anaerobic respiration ? To metabolise the lactate 7 of 11 What is this extra oxygen known as? Oxygen debt -the extra O2 is also used to resynthesise depleted ATP 8 of 11 What is the end product of anaerobic respiration in plants and fungi? Ethanol and CO2 9 of 11 What happens to the ethanol? Eliminated as a waste product 10 of 11 Why is anaerobic respiration beneficial to plant and fungi? Allows organism to survive for a period of time without O2 11 of 11
