• During cellular respiration, the energy stored in the chemical<br />
bonds of food molecules is converted to the high energy<br />
molecules, ATP. Depending on the availability of oxygen,<br />
cellular respiration can take two paths. The anaerobic path<br />
(fermentation) does not require oxygen and yields little ATP.<br />
The aerobic path (citric acid cycle and electron transport<br />
chain) requires oxygen and yields much more ATP. Both paths<br />
start with glycolycis.<br />
• All of the reactions of cellular respiration also create heat.<br />
Aerobic cellular respiration in a homeotherm (gerbil).<br />
Homeotherms maintain a constant internal body temperature<br />
despite changes in the environment. One way that<br />
homeotherms maintain this constant temperature, is by<br />
adjusting their raters of cellular respiration - higher<br />
respiration rates create more heat. Because aerobic<br />
respiration requires oxygen, we will estimate aerobic<br />
respiration by measuring oxygen consumption.
