4 cards from this section. Quick, good the night before a test.
What does the RQ represent?
Think about the gases exchanged during respiration.
What is the RQ when carbohydrates are oxidized?
Recall the reaction for glucose oxidation.
What is the value of RQ when carbohydrates are used during respiration?
Remember the glucose oxidation reaction.
True or False: The respiratory quotient for fats is greater than 1.
Consider how energy is released during fat metabolism.
Calculate the RQ for a mixture of substrates: 100 grams of glucose and 200 grams of fatty acids. Assume complete combustion of glucose and partial oxidation of fatty acids.
Refer to the respective energies of glucose and fatty acid oxidation.
Discuss the implications of using pure fat as a respiratory substrate in a long-duration exercise scenario.
Think about energy needs versus recovery time after prolonged exercise.
