CELLULAR RESPIRATION Chemical Pathways

Cellular Respiration: Occurs in the Mitochondria (“Power House”) Is a process of releasing the energy from FOOD (glucose) to make ________________ ATP (Energy)

_____________ + _________ → ________ + __________ + __________ CELLULAR RESPIRATION C 6 H 12 O 6 6O 2 6 CO 2 6 H 2 O

________ (Including _______) ALL LIVING THINGS NEED ENERGY! What kind of organisms use respiration? plantsfungibacteria ______ animals humans

There are two types of respiration: 1.Aerobic 2.Anaerobic With Oxygen Without Oxygen

Aerobic Respiration: C 6 H 12 O 6 + 6O 2  6CO 2 + 6H 2 O + Energy Requires OXYGEN Makes additional Energy (38 ATP)

Anaerobic Respiration: Does not require oxygen. Occurs in the cytoplasm. -No extra energy is made (2 ATP) 2 Kinds: 1.Lactic Acid 2.Alcohol Fermentation

Lactic Acid: -When you exercise, you need oxygen and more energy -If you do not get oxygen to your muscles fast enough, your body will produce lactic acid instead of ATP (energy) -This causes soreness in your muscles

Lactic Acid: -This is also how certain foods are made such as yogurt, cheese, pickles, and sour cream

ALCOHOLIC FERMENTATION Product of this type of anaerobic respiration Is ethanol (a type of alcohol) Happens when yeast makes bread dough rise CO 2 bubbles make _____________ in bread Alcohol _______________ during cooking air spaces evaporates

ALCOHOLIC FERMENTATION Happens when ___________ makes _______ or ____________ makes ______ yeastbeer bacteria wine
