Ketosis occurs when the body does not have any glucose stores left. So it has to switch to some other process to get energy. One process is gluconeogenesis in which the body creates glucose from fat/protein. The other is ketosis which is literally referes to the creation of ketone bodies from fat/protein.
C'mon Baby, Light My Fire. The ingredients needed to start a fire are traditionally illustrated in the fire triangle. The three legs of the triangle are fuel, oxygen and heat. When enough of these three factors is present, a chemical reaction occurs that results in fire. This is why you can start a fire with two sticks: The fuel is the sticks, the oxygen comes from the air and fiction provides the necessary heat. But this is far from the only circumstance in which friction starts a fire.
Technically however fire is a form of combustion. Combustion is defined as a self sustaining chemical reaction yielding energy or products that cause further reactions of the same kind. Fire is defined as a rapid self-sustaining oxidation process accompanied by the evolution of heat and light of varying intensities. The 3 components necessary for a fire to occur are; 1. HEAT-the energy component it supports combustion through pyrolysis. 2.
