Organelles & Compartmentalisation (HL IB Biology)

The diagram below shows a ribosome producing proteins that are to be secreted from the cell. In order for this to occur, the ribosome must bind to organelle X.

State the name of organelle X.

Binding to Y will result in the ribosome moving towards organelle X and binding to Z.

Identify Y and Z in the diagram.

State the effect that binding to Y would have on the process of translation.

Describe the path of the protein after it is produced, until it is secreted out of the cell.

Ribosomes play an important role during the process of translation.

Describe the structure of ribosomes.
