Explanation / Answer

(since you have posted many questions together, I am answering the first four)

75. False. Membranes are made of two layers of lipids.

76. False. Each NADH generates 2.5 to 3 molecules of ATP.

79. True. This can be seen in ER or Thylakoids.

80. True. NADH is a valuable form of reducing energy inside the cell.
