1. Pyruvate enters the mitochondria without oxygen
Once glucose molecule (monosaccharide) from starch or glycogen (polysaccharide) is broken-down by glycolysis in the cytoplasm (=cytosol) to pyrruvate.

Pyruvate enters the mitochondria with oxygen

2. ppppppooooooo
Once glucose lecule (monosaccharide) from starch or glycogen (polysaccharide) is broken-down by glycolysis in the cytoplasm (=cytosol) to pyrruvate.

3. One glucose molecule

4. Pyruvate without oxygen in the mitochondria with enzyme
Starch or glycogen (polysaccharide) is broken down to one glucose molecule (monosaccharide). The one glucose molecule (monosaccharide) is broken-down by glycolysis to pyruvate in the cytoplasm (cytosol) with enzymes.
Pyruvate without oxygen in the mitochondria with enzyme
Aerobic respiration in animals & plants produced 36ATP + carbon dioxide + water.

5. One glucose molecule (monosaccharide) from starch or glycogen (polysaccharide) by glycolysis to make pyruvate in the cytosol,
