Why does anaerobic respiration takes place in muscles during exercise?
Because the Liver and Brain cannot supply oxygen to the muscles cells quickly enough.
Because the Lungs and Heart cannot supply oxygen to the muscles cells quickly enough.
Because the Liver and Heart cannot supply oxygen to the muscles cells quickly enough.
Because the Kidneys and Bladder cannot supply oxygen to the muscles cells quickly enough.
Why do muscles become fatigued (tired) during long periods of vigorous activity?
Citric acid builds up in the muscles from anaerobic respiration.
Lactic acid builds up in the muscles from anaerobic respiration.
Hydrochloric acid builds up in the muscles from anaerobic respiration.
Lactic acid builds up in the muscles from aerobic respiration.
What is oxygen debt ?
A temporary carbon dioxide shortage in the body tissues arising from exercise.
A permanent oxygen shortage in the body tissues arising from exercise.
A temporary nitrogen shortage in the body tissues arising from exercise.
A temporary oxygen shortage in the body tissues arising from exercise.
When your body repays it's oxygen debt what is lactic acid broken down into?

Which organ removes lactic acid from the blood
Kidneys
Lungs
Liver
Bladder
What is Metabolism?
All the chemical reactions involved in maintaining the living state of an organism and it's cells.
The food we eat
Chemical reactions in plants
Chemical reactions in animals
The energy transferred by respiration in cells is used by the organism for the processes of metabolism. What molecules speed up these reactions?
Hormones
Antibodies
Antigens
Enzymes
