Respiration and Photosynthesis - Response to Exercise Flashcards
what demand is increased in the human body when exercising
the demand for energy
what increases in the human body during exercise and why
the heart rate, breathing rate and breath volume
to supply the muscles with more oxygenated blood
what happens if insufficient oxygen is supplied
anaerobic respiration takes place in muscles
what does the incomplete oxidation of glucose cause
it causes a build up of lactic acid and creates an oxygen debt
what happens during long periods of vigorous activity
muscles become fatigued and stop contracting efficiently
what transports the lactic acid to the liver and why
blood flowing through the muscles transports the lactic acid to the liver so it can be converted back into glucose
what is oxygen debt
oxygen debt is the amount of extra oxygen the body needs after exercise to react with the accumulated lactic acid and remove it from the cells
