Question

A colleague gives you two membrane fractions from a plant cell lysate. One contains the plasma membrane fraction, the other the mitochondrial fraction. The tubes are not labeled, but you run the samples anyway, looking at the macromolecule composition of the samples. You know for certain that the second sample contains the mitochondrial fraction simply because it contains insignificant amounts of:________. A) lipids. B) protein. C) carbohydrates D) specifically phospholipids. E) both choices C and D

Answer 1

C) carbohydrates

Step-by-step explanation:

Note that, Mitochondria is a tiny cellular structure that performs specific functions within a cell, The plant cell lysate is a fluid that contains the contents of lysed cells.

Because mitochondria take food molecules in the form of carbohydrates and combine them with oxygen it would be obvious certainly that the second sample contains the mitochondrial fraction simply because it contains insignificant amounts of carbohydrates .
