Respiration- Chemical Reaction that makes energy

ATP

What’s the difference between aerobic and

anaerobic respiration?

Anaerobic Respiration• Also known as fermentation• No oxygen is used• Glucose is needed• Only 2 ATP made• Occurs in the cytoplasm – 2 Types:1) Alcoholic Fermentation2) Lactic Acid Fermentation

Alcoholic Fermentation• Occurs in yeast and bacteria

Glucose 2 Ethyl Alcohols + 2CO2 + 2 ATP

Lactic Acid Fermentation• Occurs in animals- causes muscle

fatigue Glucose 2 Lactic Acids + 2CO2 + 2 ATP

Aerobic Respiration• Oxygen is needed• Occurs in mitochondria (cell organelle)• More efficient 36 ATP made

Glucose + Oxygen Carbon Dioxide + Water + 36 ATP

ALSO SHOWN AS:

C6H12O6 + O2 CO2 + H20 + 36 ATP

• Mitochondria

ATP ADP releases ENERGY• ATP – adenosine triphosphate (3 Phosphates)

• When ATP is hydrolyzed (+ water) energy is released and ADP is formed (adenosinediphosphate -2 Phosphates)

• HOH + ATP ADP + P + ENERGY

• This reaction is reversible

• Enzyme is ATPase

Respiration is the opposite of Photosynthesis
