Cellular RespirationWhat we do with our energy

Anaerobic vs. aerobic Uses no oxygen Makes a little energy

Uses oxygen Makes a lot of energy

Overview Of Cellular Respiration Cellular respiration is the

process that releases energy by breaking down glucose and other molecules in the presence of oxygen. Occurs in the

Mitochondria

To release energy from food molecules and make ATP!

Why do we need ATP? ATP is the energy molecule needed by our cells Our cells use ATP to make all of the chemical

reactions in our body run.

Purpose of cellular respiration?

Summary equation for Respiration

Anaerobic respiration Not enough oxygen for aerobic respiration

Fermentation-releases energy from food molecules by producing ATP in the absence of oxygen. (Anaerobic = no oxygen)

Two types: alcoholic fermentation, lactic acid fermentation

Lactic acid vs alcoholic No oxygen Occurs in muscles Pyruvates lactate Occurs so muscles can

continue making ATP Get lactate build up in

muscles Causes soreness

No oxygen Pyruvate carbon

dioxide & ethanol Seen in yeast and

fungus Used to make

beverages, food, makes dough rise

Overall Cellular Respiration breaks down

Glucose (C6H12O6). It produces H2O and CO2 It produces 36 ATPs!
