across the plasma membrane? Produce a diagram explaining the
mechanism of action of T3 at a cellular level.
Plasma Membrane. What is the composition of
plasma membrane (PM) of a bacterial cell? How does this compare to
a eukaryotic cell? List the functions of the PM. Without complex
internal membranes, where do prokaryotes carry out membrane-bound
chemical reactions such as ATP synthesis or photosynthesis?

a) DNA sythesis
b) protein synthesis
c) RNA synthesis
d) b and c
e) all of the above

Explain the importance of glycolipids in the plasma membrane,
identify where they are produced inside the cell, and describe the
mechanism by which they are transported to the plasma membrane and
presented to the extracellular environment. Draw a diagram to
support your answer.
Plasma membranes are underrated. Describe how aspects of the
plasma membrane structure (physical components and their
arrangement) enables FOUR aspects of neuronal activity. Use the
terms 'semi-permeable' and 'fluid mosaic' in your response.
Short and simple answers welcome.
Describe the fluid mosaic model of the plasma membrane. Discuss
the role of the membrane in the movement of materials through it by
each of the following processes.
Active transport
Passive transport
Describe negative and positive feedback loops, and discuss how
feedback mechanisms regulate each of the following.
