CELLULAR RESPIRATIONCELLULAR RESPIRATION• All cells take food and turn it into
energy the organism can use
• Takes place in the mitochondria of cells
What organelle does cellular respiration take place in?
ATPATP• ATP is a molecule inside cells that acts like
a rechargeable battery carrying small amounts of instantly available energy
P P P
ATPATP• Cellular Respiration makes ATP by using
ENERGY to add a phosphate to a molecule called ADP
P P
ENERGY
P
ATPATP• The ENERGY is stored in the chemical
bond between the second and third phosphate

EXERCISE AND ENERGYEXERCISE AND ENERGY
• Exercise takes energy• Organisms get energy from cellular
respiration• Cellular respiration takes oxygen• This is why you tend to breathe hard
when you use a lot of energy—Your cells are trying to get enough oxygen to get the energy.
AEROBICAEROBIC
• Aerobic means that it uses oxygen
• Cellular respiration is aerobic
• Some exercises are considered aerobic because your body is using energy at a slower pace so that your body can get enough oxygen to perform cellular respiration
ANAEROBICANAEROBIC• Anaerobic means that it does NOT use oxygen• If there is not enough oxygen to perform cellular
respiration, then FERMENTATION FERMENTATION occurs• FERMENTATION FERMENTATION
allows organisms to get energy when oxygen is not available
• Lactic acid fermentation occurs in animals
• Alcoholic fermentation occurs in plants
ANAEROBICANAEROBIC• Some exercises are considered anaerobic because
your body is using energy at a FASTER pace so that your body CANNOT get enough OXYGEN to perform cellular respiration
• For example: during short, fast races you might get a burning feeling in your leg muscles because of a build up in lactic acid (made during fermentation)
