Aprotein that is destined to be secreted from the cell has a signal sequence that targets it to the plasma membrane
- is targeted to the rer as a soluble protein.
- is made solely by ribosomes free in the cytosol.
- is targeted directly to lysosomes.
- has a signal sequence that targets its translation into the lumen of the rer.

A protein that is destined to be secreted from the cell:

- is targeted to the RER as a soluble protein.

Explanation:

The main function of the RER is the synthesis and transport of secretion or membrane proteins.

If you are looking for the RER you could fount it on eukaryotic cells, side by side of the nucleus, and cover in ribosomes.

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
