Answer key

1. C, 2. A, 3. C, 4. D, 5. B, 6. C

  1. Thylakoids contain chlorophyll and the light dependent reactions.

  2. The Calvin cycle occurs in the stroma of the chloroplast.

  3. Glycolysis occurs in the cytoplasm.

  4. Two ATP are used and four are made, giving a net of 2.

  5. It takes place in the matrix of mitochondria.

  6. Oxygen accepts electrons and forms water.
