what is the respiratory quotient
the ratio of carbon dioxide molecules produced to oxygen molecules taken in during respiration
true/false
different respiratory substrates have different typical RQ values
true
why do different respiratory substrates have different RQ values
because of the number of carbon-hydrogen bonds differs in each biological molecule
what is the RQ of glucose and why
1 because when respired aerobically equals amounts of carbon dioxide are produced to oxygen taken in
what is the RQ value of carbohydrates
1
what is the RQ value of lipids
0.7
what is the RQ value of proteins
0.9
the respiratory quotient is calculated from
respiration equations
calculation of an RQ value step 1
create respiration equation
calculation of an RQ value step 2
balance the equation
calculation of an RQ value step 3
create the full equation
calculation of an RQ value step 4
use RQ formula
why can no RQ value be calculated for anaerobic respiration in muscle cells
no oxygen is used and no carbon dioxide is produced during lactate fermentation
why can no RQ value be calculated for anaerobic respiration in yeast cells
it tends toward infinity as no oxygen is used while carbon dioxide is still produced
