aerobic respiration what pyruvic acid undergoes with no oxygen present fermentation type of reaction in cellular respiration redox reaction cellular respiration equation where the reactions of glycolysis take place step one glycolysis step two glycolysis step three glycolysis

1. aerobic respiration

pyruvic acid is broken down and NADH is used to make lots of ATP

2. what pyruvic acid undergoes with no oxygen present

fermentation

3. fermentation

the breakdown of pyruvic acid by enzymes, bacteria, yeasts, or mold in the absence of oxygen

4. type of reaction in cellular respiration

redox

5. redox reaction

one reactant loses electrons and another gains electrons

6. cellular respiration equation

C6H12O6+6O2---> 6CO2+6H2O+ATP

7. where the reactions of glycolysis take place

cytosol

8. step one glycolysis

two phosphate groups are attached to one molecule of glucose, ATP converted to ADP

9. step two glycolysis

6-carbon molecule split into two 3-carbon molecules of G3P

10. step three glycolysis

G3P molecules lose electrons and receive another phosphate group, two molecules of NAD+ converted into NADH
