Explanation / Answer

27. The proton transfer from matrix to the inner membrane space where they are accumulated.

28. The electron transport chain of bacteria is in the plasma membrane as mitochondria are absent.

29. The components from electron transport chain are embedded in the inner mitochondrial membrane.

30. The thylakoid membrane contains light absorbing pigments.

31. Protons are accumulated in the thylakoid space.
