An analysis of a cell indicated a high lipid content in the membranes, a high protein content in the vesicles being mobilized and transported throughout the cell, and a high carbohydrate content within the cytoplasm. The researcher performing the analysis
concludes that the compounds must serve different roles in the cell. However, a chemical analysis of these three compound types
is also performed. Which comparison BEST illustrates the similarity and difference in the elemental makeup of these molecules?
A)
B)
Carbohydrates and proteins both contain carbon, hydrogen, and oxygen
atoms, while the lipids contain sulfur in addition to those three elements.
Carbohydrates and lipids both contain carbon, hydrogen, and oxygen
atoms, while the proteins contain nitrogen in addition to those three
elements
Carbohydrates and proteins both contain carbon, hydrogen, and oxygen
atoms, while the lipids contain nitrogen in addition to those three
elements
Carbohydrates and lipids both contain carbon, hydrogen, and oxygen
atoms, while the proteins contain phosphorus in addition to those three
elements
D)
