(b(i))[1]
State the place in the body where the neutrophil develops and matures.
(b(ii))[1]
Describe the shape of the nucleus in a mature neutrophil.
(b(iii))[1]
State the alternative name for the cell structures labelled as “granules” in Fig. 6.2.
(c(i))[2]
Primary granules contain proteins called defensins. These attach to bacterial cell-surface membranes and make very small pores in the membrane. Suggest how defensins help the neutrophil kill bacteria.
(c(ii))[2]
Secondary granules contain lysozyme. This enzyme breaks bonds in peptidoglycan molecules. Explain how lysozyme activity will cause the bacterial cell to be destroyed.
