Respiratory quotients 0.0 / 5 ? BiologyBiological molecules, organic chemistry and biochemistryA2/A-levelCCEA Created by: Football03Created on: 20-02-22 15:25 What is RQ? A ratio of gas exchange ,calculated by comparing the O2 uptake with the CO2 evolved. 1 of 10 What is RQ used for? -To evaluate the type of substrate being used -The type of respiration taking place 2 of 10 What is the equation for RQ? RQ=Volume of CO2 released/Volume of O2 consumed 3 of 10 Anaerobic respiration equation? C6H1206 + 6O2 = 6CO2 + 6H2O +ATP (energy) 4 of 10 RQ Values of carbohydrates,protein,lipid and alcoholic fermentation? -Carbohydrate = 1 -Protein =0.9 -Lipid=0.7 -Alcoholic fermentation=infinity 5 of 10 What is the 'normal' RQ value? 0.85(combination of carbohydrate and lipid) 6 of 10 What does an RQ value of more than 1 indicate? That some anaerobic respiration is taking place 7 of 10 Anaerobic respiration in animals does not produce...? CO2 8 of 10 In humans after a meal rich in carbohydrate RQ will be close to ? RQ will be close to 1 but after a number of hours it will fall as lipids are being respired 9 of 10 Lipids only respire ...? Aerobically 10 of 10
