Glucose + Oxygen = Energy to Contract and produce heat

Glucose: stored in the muscles as glycogen

Oxygen: used to burn glucose into energy

Glucose + O2 = Energy for contraction and heat

Waste Products produced are CO2 and Water

Carbon Dioxide and Water: waste products from the production of energy for muscles

Lactic Acid: causes the “burn” in muscles from a lack of oxygen

(Without O2, glucose breaks down into lactic acid)
