Answer: Cell membrane

Explanation:

The cell membrane has the ability to transfer the molecules from the exterior of the cell to the interior of the cell.

The cell membrane is semi permeable which means only selected molecules will pass through the cell membrane.

The molecules and substances that are synthesized inside the cell needs to be transported from inside to outside via cell membrane.

A.

I say this because there are other ways to make DNA in plant cells like adenine, cytosine, guanine, and thymine so B is out. Though, Mitochondria does break down waste so part of B is right but that would cancel out C. Without Chloroplasts, a plant cannot make food so D is out as well. Hope this helped!

Answer:

D. The methyl group of acetyl CoA becomes radio-labeled

Explanation:

During the steps in glycolysis, the carbon at position 1, becomes C-1 in dihydroxyacetone phosphate during the cleavage of fructose-1,6-bisphosphate to dihydroxyacetone phosphate and glyceraldehyde-3-phosphate. Subsequently on isomerization of dihydroxyacetone phosphate to glyceraldehyde-3-phosphate, C-1 of dihydroxyacetone phosphate becomes C-3 of glyceraldehyde-3-phosphate.

Furthermore, in pyruvate, the end product of glycolysis, C-3 is converted to a methyl group which then becomes the methyl group in the acetyl-CoA molecule produced from the oxidative decarboxylation of pyruvate.

Since the radioactive 14-C of radio-labeled glucose occupies position 1, it will become the methyl group of acetyl-CoA.
