Describe the genetic code and its relationship to polypeptides and proteins.
Outline the role of proteins in active and passive transport of molecules through membranes.
Many cell functions, like synthesis of macromolecules and transport, require energy in the form of ATP. Explain how ATP is generated in animal cells.
Identify the structures labelled I, II and III in the micrograph above and give a role for each one.
Using the letter A, identify one location on the micrograph where transcription takes place.
Using the letter B, identify one location on the micrograph where chemiosmosis occurs.
Suggest what product each cell is likely to be making.
Explain how the products are transported from the site of production and released from the islet cells.
