lactic acid+ oxygen -> water +carbon dioxide+glucose

Question 5

oxygen debt

Answer 5

a temporary oxygen shortage in the body tissues arising from exercise

Question 6

excess post exercise oxygen consumption(EPOC)

Answer 6

the process of taking in the additional oxygen needed by the cells in the body in order to remove the lactic acid created by anaerobic respiration.
