For oxidative phosphorylation, 2.5 ATP are produced per NADH and 1.5ATP per FADH2. (Approx.)
Respiratory quotient (RQ) is the ratio between the volume of CO2 produced and the volume of Oxygen consumed by a respiring system. Concentration of oxygen in the environment when the RQ of a system is one, is referred to as the extinction point.
Complete oxidation of one molar concentration of glucose (180 g) by aerobic respiration consumes 192 g of oxygen as it produces 264 g of CO2 , 108 g of water and releases 686000 calories.
Non-germinating live seeds and grains respire by way of lactic fermentation and their Respiratory quotient (RQ) would be undefinable, irrespective of the nature of their nutrient reserves. They switch over to aerobiosis only upon germination.
