Hi there, As you have not requested for a question in particular, so I would like to answer the first four questions. Answer 34) The correct answer is D) phagocytosis. All the processes, except phagocytosis are involved in material transport because of a presence of semi-permeable membrane. Phagocytosis in particular, involves the actin-based movement of cell membrane whenever its receptor recognises a solid particle to be engulfed. This flexibility cannot be achieved with a cell containing a cell wall. Answer 35) The correct answer is D) NADH and FADH2 . Acetyl CoA produced from pyruvate is acted upon by removing electrons from it and which are furthur used to reduce NAD+ with FAD as another electron carrier, together these produce NADH and FADH2 which generates energy via ATP. Answer 36) The correct answer is C) Activation energy. Every reaction whether energy releasing (spontaneous) or energy requiring, it has to have a energy input in form of activation energy to make up for transition state, which is highly unstable high energy state. For every chemical reaction that requires breaking of bonds, it has to have a small energy input prior to release of its own energy by breaking of bonds. Answer 37) The correct answer is B) They absorb and transfer light energy to reaction centre chlorophyll. The pigments present in photo-systems absorb energy from sun, and pass onto reaction centre, containing chlorophyll, which has a function later to convert this light energy into chemical energy as ATP.

Hope this helps.
