I think Ketogenesis because Ketogenesis gives ATP from beta-oxidation. Lypolysis and Ketogenesis are related.

I took part in a quiz in which the following question was asked: "Your bodily functions stop when you sneeze. True or false?" I answered "false", but the quizmaster said it was true. Does he have a case, and if so, what happens physiologically when you sneeze?

It has become "common knowldege" in my SCUBA club that a huge number of calories are used on a simple dive. It makes complete sense that the effects of cold water (as low as 7 C) would lead to an increased rate of metabolism but the member are adamant (particularly the Drysuit divers) that the increased pressure of gases in the system is the main cause. 

So does the pressure effect of SCUBA diving have an effect on energy consumption, if so how?

Do I throw back the bed clothes to make my body work harder to keep me warm, or do I pull on an extra blanket to help increase my metabolic rate?

Which effect dominates? Is either significant?

Our bodies use energy to cool us down in hot environments (sweat) and warm us up in cold environments (shivering). If our internal body temperature is roughly 37 degrees C what is the ideal temperature of the environment that we would use least energy taking into account heat released from our metabolic activity?

In common parlance, one would say the body 'burns' food, and, indeed, we are warm creatures due to some kind of exothermic reaction(s) inside us, yet our muscles and brain work on electrical impulse. Is this the most efficient conversion of heat to useful energy we know of, or is the electrical energy converted from chemical potential energy somewhere?
