1) Anaerobic respiration produces ethanol, in the cytoplasm, as opposed to aerobic in the mitochondria

2) Ultrafiltration requires blood at high pressure for filtration. Blood is pumped from the heart to the kidneys, hence the energy has originated from the heart's tissue (left ventricle to the body)
