Question

to make sure you understand the flow of events in the endomembrane system, drag and drop each statement into the correct order. place the first event at the top and the last event at the bottom. processed proteins and other products move to the golgi from er through \connection tunnels\. mrna is exported from the nucleus, through a nuclear pore. products move through each sac in the golgi, being processed, sorted by destination, and loaded into a vesicle. vesicles arrive at their destination and empty their cargo. kinesin walks along microtubules to carry vesicles that bud off the golgi to their destination. a signal sequence on the new protein binds to an rna - protein particle, which interacts with a receptor on the er membrane. the protein enters the inside of the er, through a channel. folding and other processing occurs inside the er. protein synthesis (linking amino acids via peptide bonds) begins in a ribosome.

Explanation:

Protein synthesis starts in ribosome. Then mRNA is exported from nucleus. New protein's signal sequence binds and enters ER. Processing occurs in ER. Processed products move to Golgi, are further processed there, loaded into vesicles. Kinesin carries vesicles to destination and vesicles empty cargo.

Answer:

1. Protein synthesis (linking amino acids via peptide bonds) begins in a ribosome.
2. mRNA is exported from the nucleus, through a nuclear pore.
3. A signal sequence on the new protein binds to an RNA - protein particle, which interacts with a receptor on the ER membrane.
4. The protein enters the inside of the ER, through a channel.
5. Folding and other processing occurs inside the ER.
6. Processed proteins and other products move to the Golgi from ER through "connection tunnels."
7. Products move through each sac in the Golgi, being processed, sorted by destination, and loaded into a vesicle.
8. Kinesin walks along microtubules to carry vesicles that bud off the Golgi to their destination.
9. Vesicles arrive at their destination and empty their cargo.
