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:

• For the first question, the rough endoplasmic reticulum (ER) is studded with ribosomes which is what differentiates it from the smooth ER.
• For the second question, proteins modified in the rough ER move to the Golgi Apparatus and other organelles via the secretory pathway.
• For the third question, one of the main functions of the ER is to transport proteins and lipids.

Answer:

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