integration and measurement of CHO and Fat metabolism Flashcards
1
Q
CPT 1 is very sensitive to
A
drop in Ph / increase in H ions
2
Q
Comparing fuels: CHO vs lipid
A
CHO is 10 % more O2 efficient
permits exercise at higher intensity because oxygen delivery limiting at high intensities
3
Q
direct
A
based on measure of heat production
1 kcal = increase of 1 kg water by 1 C
4
Q
indirect
A
-based on measure of oxygen utilization
-fuel use can also be determined
5
Q
O2 uptake of 1.0 L
A
5 kcal
6
Q
RER
A
ratio of CO2 produced to O2 consumed
7
Q
RER: Theoretical Basis
A
- O2 needed to combust a given unit of food is constant
- O2 needed to combust
8
Q
RER assumption
A
no protein contribution
steady - state only
limitation ate the assumptions
9
Q
A
