	TRUE-FALSE

F	26. Chloroplasts will usually perform cyclic photophosphorylation since this reaction produces both ATP and NADPH₂.
T	27. The oldest or most primitive group of reactions involved in respiration are believed to be the glycolysis reactions.
F	28. Another name for the process of cytoplasmic streaming is osmosis.
F	29. Oxygen gas is released from the Calvin Cycle reactions of photosynthesis and used during cyclic photophosphorylation.
T	30. Active transport is the only concentrating mechanism that we have which can move molecules from areas of lower concentration to areas of higher concentration.
T	31. Most of the ATP produced in aerobic respiration is produced by the cytochromes of the electron transport system.
F	32. The experiments of Pasteur and Virchow helped to disprove the Cell Theory of Hooke and Leeuwenhoek.
T	33. The final electron acceptor of aerobic respiration is Oxygen.
T	34. The chromatin net coils or condenses to form chromosomes only during the time of cell division.
T	35. Prokaryotic cells are much simpler than eukaryotic cells in terms of their structure.
