Answer 1

1. Fermentation follows glycolysis in the cytosol if there isn't any oxygen available. -A-
2. Answers B and C are both correct; both happen using light energy during the light dependent reactions -D-
3. -D- This doesn't happen at all. The oxygen given off during photosynthesis comes from splitting water molecules, not carbon dioxide.
4. -D- Mitochondria and chloroplasts both contain DNA.

Answer 2

1.Ferementation takes place in the cytoplasm of the cell. try cytosol according to this diagram
