What are the two ways cells make ATP? What is a redox reaction? What does all energy metabolism have in common? What happens to the energy released in catabolic processes? In glycolysis, usable energy is captured in the form of what mole? In the Citric Acid Cycle (also called the Krebs Cycle, tricarboxylic TCA cycle), usable energy is captured in the form of what molecule? In oxidizing glucose all the way through glycolysis and the Krebs the low energy products and the high energy products? The equation for aerobic respiration can be summarized as C_6H_12O_6 + 6O_2 rightarrow 6CO_2 + 6H_2O + energy Which molecule is being oxidized? Which is being reduced? What is oxidative phosphorylation? What is ATP Synthase? How does it work and what does it do? How do respiration and fermentation differ? Under what circumstances does a cell carry out fermentation? Why are fermentation reactions important for cells under those How are lactic acid fermentation and ethanol fermentation alike different?

Explanation / Answer

23. Cells can make ATP by 2 ways. The first one is glycolysis in which glucose is broken down 2 molecules of pyruvate the process usually takes place outside mitochondria in the cytoplasm.

This pyruvate undergoes cellular respiration to prodyce carbon dioxide and ATP.

The other way is fermentation. In fermentation the pyruvate is converted into lactic acid or ethanol and this process takes place in absence of oxygen.
