DIFFERENCE BETWEEN AEROBIC & ANAEROBIC ENERGY SYSTEM

AEROBIC

EXAMPLE

cycling

running

swimming

Occurs in mithochondria

Glucose completely broken down

Produces carbon dioxide, water & energy

38 molecules of ATP or 2898 kJ

Release more energy

Oxygen present

ANAEROBIC

EXAMPLE :

heavy weight lifting

sprinting

jumping

Occurs in cytoplasm

Glucose NOT completely broken down

Produce lactic acids & energy (muscle cells) or ethanol, co2, energy (yeast)

2 molecules of ATP or 150 KJ (mucle cells), 210 KJ (yeast)

Release less energy

Oxygen absent
