1.	define 1. odometer 2. aerobic respiration and anaerobic respiration
Answer» <p>1. Odometer- an instrument for measuring the distance travelled by a wheeled vehicle.2. Aerobic respiration- Aerobic respirationis the process of producing cellular energy involving oxygen. </p><p>Cells break down food in the mitochondria in a long, multistep process that produces roughly 36 ATP. </p><p>The first step in is glycolysis, the second is the citric acid cycle and the third is the electron transport system.</p><p>3. Anaerobic respirationisrespiration using electron acceptors other than molecular oxygen (O2).</p><p>These terminal electron acceptors have smaller reduction potentials than O2,meaningthat less energy is released per oxidized molecule. </p><p>Therefore anaerobic respirationis less efficient than aerobic</p>
