Answer 2

                             Glucose (6 carbon mlecule)

                                  ↓  (in cytoplasm by glycolysis)

                             Pyruvate (3 carbon molecule)

                            + energy

                                  ↓

1.in the presence of oxygen (in mitochindria)

$H_{2}O + CO_{2} + Energy$

2.in the lack of oxygen (in muscle cells)

$Lactic Acid + Energy \\(3 carbon molecule)$

3.in absence of oxygen ( in yeast)

$Ethanol+CO_{2} + energy$
