| Which of these organelles in NOT associated with the production or sorting of proteins in a cell? | Smooth endoplasmic reticulum (SER) |
| Choose the sequence that best describes the progress of an enzyme from synthesis to its final destination in a lysosome: | Rough endoplasmic reticulum; cis face of Golgi apparatus, trans face of Golgi apparatus, vesicle, endolysosome |
| Plant cells differ from animals cells because they have: chloroplasts, cell walls and vacuoles | True |
| What does a polyribosome consist of? | several ribosomes translating a single mRNA molecule |
| Organelles enclosed by a double membrane include: the Golgi apparatus and the lysosomes | False |
| The cytoskeleton provides support, structure, motility, and organisation. Which part of the cytoskeleton forms tracks to direct organelle and vesicle transport. | microtubules |
| Rough ER is associated with ribosomes and critical for protein synthesis in the cell | True |
