Question
Chapter 27, Problem 18P
Interpretation Introduction
(a)
Interpretation:
RQ value for glucose oxidation and tripalmitoylglycerol should be calculated.
Concept introduction:
RQ (respiratory quotient) value is the ratio of the volume of carbon dioxide produced to the amount of oxygen gas required in respiration process over a fixed period of time. Its value can be zero, less than one, one, and more than one.
Interpretation Introduction
(b)
Interpretation:
The use of RQ measurements of different energy sources during intense exercise should be determined.
Concept introduction:
RQ (respiratory quotient) value is the ratio of the volume of carbon dioxide produced to the amount of oxygen gas required in the respiration process over a fixed period of time. Its value can be zero, less than one, one, and more than one.

different energy sources during intense exercise? (Assume that
protein degradation is negligible.)
these are KT values. Which transporter that is a GLUT will transport glucose from blood which is 5nm at the maximum or Vmax?
Is it (GLUT 11,KT= 0.1M), (is it GLUT1, KT = 3nm), (is it GLUT 2, KT= 17nm), (or GLUT 4, KT = 5nm)
