Cellular respiration breaks down glucose to release energy and form ATP. Process requires oxygen and occurs in all living things. Chemical equation: C6H12O6 6O2 → 6CO2 6H2O
Cellular respiration converts nutrients into ATP using oxygen as electron acceptor. Process occurs in all cells of plants and some bacteria. Can be aerobic (requiring oxygen) or anaerobic (without oxygen)
Mitochondria are double-membraned organelles in eukaryotic cells. First described by Richard Altmann in 1890. Named from Greek words meaning "thread" and "granules-like"
Cellular respiration converts foodstuffs' chemical energy into ATP for cellular processes. Oxygen-dependent organisms use cellular respiration, anaerobic organisms use fermentation. Mitochondria contain enzymes for respiration in eukaryotic cells
Aerobic respiration breaks down glucose with oxygen to produce ATP. Process occurs in mitochondria, starting in cytoplasm. The balanced equation: C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy
Converts NADH and FADH2 oxidation energy into ATP through oxidative phosphorylation. Occurs in mitochondria's inner membrane as four protein complexes. Utilizes body's ATP supply about 300 times daily
