Aerobic Respiration (Leaving Cert Biology): Flashcards

Enzyme-controlled release of energy from food using oxygen

$C_6H_{12}O_6 + 6O_2 \to 6CO_2 + 6H_2O + ATP$

Glycolysis; Krebs cycle & electron transport chain

Cytosol (cytoplasm without organelles)

Anaerobic (does not require oxygen)

2 ATP molecules

Two 3-carbon pyruvic acid (pyruvate) molecules

Mitochondria

Acetyl coenzyme A (acetyl CoA) - 2-carbon molecule

$CO_2$ and $H_2O$

Increase surface area for more reactions & energy production

Inner membrane (cristae) of mitochondrion

Final electron acceptor

High-energy electrons and protons ($H^+$)

Water ($H_2O$)
