proteins are being oxidized during respiration
What does a respiratory quotient of 0.7 indicate?
fats alone being oxidized during respiration
What does a respiratory quotient of 0.85 indicate?
a mix of nutrient are being used during respiraton
To lower the RQ, increase the ______ content
fat
Properties of cellulose
resistant to amylase
Adds bulk
