I said 23,000 for that reason too, so it could be able to code for all proteins and to carry out all functions etc
For the Golgi Apparatus question:
- at least 3 convex sacs ranging from smallest to largest
- the largest sac is the sac facing the ER i.e. the smallest sac is where functions are last carried out and is closest to the membrane
- the smallest sac is more condense with enzymes, which might be visible with a stain
- i drew a labelled diagram in case my explanation didnt make sense XD
For the Golgi apparatus/rER question:
- the transcripted RNA comes through the nuclear pores and attaches to the ribosomes (proteins) on the rER's surface
- the protein and genetic information travel through the rER, taking its 3D-like structure along the way
- vesicles pinch off the ends of the rER containing the protein and genetic information
- vesicles travel through the cytoplasm to the ends of the G.A's sacs, where they fuse into
- enzymes in the G.A modify the protein along its journey
- this includes the idea that if certain proteins need to be a certain direction e.g. receptors, the protein is turned in a certin way so it can be facing the rigth direction
- vesicles pinch off the ends of the G.A and travel to fuse with the cell membrane so it can carry out either intercellular/extracellular functions
