Anaerobic Flashcards
In a situation where _, organisms rely on anaerobic respiration
Little oxygen is available
Anaerobic breaks up glucose and
Releases energy without using oxygen
_ use anaerobic (2)
Bacteria
Yeast
Enzymes break glucose into _ molecules, releasing just a small amount of energy
Lactic acid
During rest or moderate activity body can
Take in needed energy aerobically
Muscles fully oxygenated with little (rest)
Lactic acid
During strenuous activity, lungs cannot supply oxygen fast enough so
Much of respiration is anaerobic
Lactic acid builds up in muscles during
Strenuous activity
During _ body takes in extra oxygen by breathing deeply
Oxygen debt
Amount of oxygen needed to _ is called oxygen debt
Break down excess lactic acid
Lactic acid _ causing burning sensation and fatigue (oxygen debt)
Chemically attacks muscles
As _ lactic acid falls (recovery)
Oxygen level rises
Lactic acid is being broken down by being _ during aerobic respiration
Oxidized
Muscles stop _ as lactic acid is removed
Hurting
