energy values

• most ATP is made during oxidative phosphorylation which requires hydrogen atoms from reduced NAD and FAD
• substrates with more hydrogen atoms per unit mass create more ATP when respired
• $RQ =$$molecules/volume of CO2 \div molecules/volume of O2$
• what is a respiratory substrate

  any biological molecule which can be broken down in respiration to release energy
• what is the RQ of glucose

  1
• RQ + 1 = anaerobic respiration
• what is the RQ of carbohydrates

  1
• what is the RQ of lipids

  0.7
• what is the RQ of proteins

  0.9
• respiratory quotients of organisms are useful as it tells you what kind of respiratory substrate an organism is respiring and what kind of respiration its using
