Question

the difference between the rough and smooth er is the rough is studded with
a proteins
b ribosomes
c lysosomes
the proteins modified in the rough er move to the golgi apparatus and other organelles through the
a secretory pathway
b photosynthesis
c nucleus
the main function of the er is to transport proteins or other molecules, such as
a water
b lipids

Explanation:

1. The rough endoplasmic reticulum (ER) is studded with ribosomes, which gives it a rough appearance. Smooth ER lacks ribosomes.
2. Proteins modified in the rough ER move to the Golgi Apparatus and other organelles through the secretory pathway.
3. The main function of the ER is to transport proteins and lipids. Water transport is not a main function of the ER.

Answer:

1. B. ribosomes
2. A. secretory pathway
3. B. lipids
