Cells and ER reticulum

Question

A cell that is able to metabolize carbohydrates in its smooth ER would not _____.

a. Use its ribosomes to synthesize proteins

b. Package molecules into transport vesicles using its Golgi apparatus

c. Have glycoprotein-secreting ribosomes in its rough ER

d. Keep its genetic material in a nucleoid region

Answer 1

The answer is D. Why? Think about where the genetic material is found in Pro vs Eukaryotes. Then notice A-C all involve membrane bound organelles, which are found in only Eukaryotes, except a. which both Eu and Prokaryotes use ribosomes to make proteins. So the nucleoid region is only found in the cytoplasm of prokaryotes, which do not have a membrane bound nucleus. Let me know if this reasoning does not make sense. I was trying to help you reason your way through the choices and base your answer on what is asked in the question
