Fuel= any material that causes the release of energy to be used for work.

For a body to use fuel, the energy in chemical bonds of the fuel must be RELEASED.

*Chemical energy must be BROKEN for the stored energy to be RELEASED *

Cellular respiration (C.R.)- Production of ATP(RELEASED) by BREAKING down carbon-based mulecules (in this case glucose) when oxygen IS present (making it aerobic).

Example of the rule for cellular respiration: The release of chemical energy from glucose and other carbon-based molecules to make ATP.(Chemical bonds must be broken for the chemical energy from glucose to be relased so ATP could be made.)

*C.R. is and Exothermic Reaction since it releases more energy than absorbed.

Process of C.R:

BREAK down glucose and other carbon-based molecules and RELEASES stored energy in chemical bonds, which is transfered to ATP.
Energy as HEAT IS also released
