Document Summary
Bioenergetics - chapters 5, 6, 7, 8 (pp 185-189) and lab and lecture notes. How is it formed: atp is the main energy currency in the body, atp = an adenosine molecule attached to three phosphates (triphosphate, when a phosphate is cleaved, energy is released during the cleavage. When you need energy fast, this glycolysis has to keep running, but the cell will run out of. When pyruvate forms lactate, nadh (only makes all its atp in the electron transport chain) will turn back into nad. This will allow glycolysis to keep happening, and form the 2 atp. What are the conditions under which it is formed: anaerobically, glucose will become lactate (without oxygen, aerobically, glucose will become acetyl coa (with oxygen) Describe the krebs cycle: if energy isn"t require right away, the pyruvates will enter another route. Instead of forming lactate, they will enter the cell"s mitochondria. Once it enters the mitochondria, it has committed to aerobic respiration.
