Question

Q1) Select all of the following categories of proteins which are made (synthesized by the Rough ER).

1) Secreted Proteins (like hormones, neutotransmitters)

2) Proteins integrated into a cell’s own plasma membrane

3) Proteins integrated into a cell’s own intracellular membranes (such as the Gogli, vesicles)

4) Proteins that are dissolved in a cell’s own cytosol

Answer 1

PROTEINS WHICH ARE SYNTHESIZED BY THE ROUGH ER ARE:

1. Secreted Proteins (like hormones, neuro transmitters)

2. Proteins integrated into a Cell's Own plasma membrane.

These proteins need to be active from their destined organelle, like hormones need to work from endocrine glands, neurotransmittors from brain.

but the proteins which are in cytosol will be synthesized by smooth ER.
