"The plasma membrane of a neuronal cell contains protein kinase C (PKC). This neuronal cell responds to electrical stimulation from other neurons by opening calcium channels, also located at the plasma membrane. In turn, these channels allow extracellular calcium to enter the cytoplasm, greatly raising its intracellular concentration. Calcium is a potent activator of PKC. Would you expect that PKC will be activated every time the neuronal cell is stimulated?"

16. which of the following accurately describes a step within transcription? a. dna polymerase uses one strand of rna as a template to put together nucleotides. b. the dna strand is used as a template for which a complementary rna strand can be produced. c. the rna strand forms a template by which dna can be built. d. the rna strand is produced within the cytoplasm.

Imagine a self-reactive t cell that has not undergone clonal deletion in the thymus (that is to say, it has escaped central tolerance). if it encounters self antigen in the absence of an infection or inflammation, what will happen to this self-reactive t cell? (select two answers) (a) the t cell undergoes clonal expansion. (b) the t cell gains effector functions. (c) the t cell undergoes apoptosis. (d) the t cell becomes activated. (e) the t cell becomes anergic.
