D,Prokaryotic genomes d. often have small circular DNA molecules that can be transferred across cells.

Explanation:

Have a great day!

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.
