5. What is the sequence of steps in the development of a digestive enzyme by the pancreas
cells from the initial transcription to the release from the cell?
a. The enzyme is transcribed from DNA by RNA in the nucleus, proceeds to the
ribosome for synthesis, and is transported in a secretory vesicle to the cell
membrane.
b. The enzyme is transcribed from RNA by DNA in the nucleus, proceeds to the
lysosome for synthesis, and is transported in an encapsulated membrane to
the cell membrane.
c. The enzyme is transcribed by the mitochondria in the nucleus, proceeds to
the ribosome for synthesis, and is transported in a cytoskeleton to the cell
membrane.
d. The enzyme is transcribed from DNA by RNA in the nucleus, proceeds to the
Golgi complex for synthesis, and is transported in cytosol to the cell
membrane.
