RE: The Respiratory Quotient - Human Energy Metabolism #2
It's sounds like lazy people who want to be less fat are better off just laying on the couch then only doing alittle bit of exercise if You have to go hard to get back to that fatty acid oxidation ;) I think I used a similar method to measure yeast activity in a college chem lab on fermentation. Thanks for the refresh I'm sure ill use this sometime as my experiments get more in depth.
One question, what is the difference between the initialy used glucose and blood glucose?
Great, that you like the post. :) Ha! You may have used some derivative of this. xD
Mhmmm.. I am not sure, what 'difference' you want to have discussed here. But here a some: The first major difference is, that the glucose stored in the muscle is already there were it is meant to be used, so it does not take a delivery, which may be a further limiting factor. This is especially important for very spontaneous workload! Second, the sugar stored in the muscle is stored as glycogen, so as an branched carbohydrate with a whole lot of 'reductive ends', which are necessary for its fast availability, since the degradation of the glycogen starts and proceeds on these ends. Have a look at the following image, where glycogen is shown:

This is the way how glycogen is built up. A protein core acts as a kind of a "growing seed" and then the glucose molecules are condensed together having a lot of branches, to provide for a great numbers of ends. The blood glucose does not have such a complex structure. - At least to my knowledge.
I hope your question is answered. Otherwise I look forward to a more specified one. ;)
Best,
