If a cell lacks a Golgi apparatus, it can never be a eukaryote. RIbosomes are characteristics of both prokaryotes and eukaryotes. D. is the best evidence that the cell is a eukaryote.
Glycolysis is the very first step in extracting the energy from the bonds of sugar. This is the breakdown of glucose to pyruvates which releases energy. One molecule of glucose produces four ATP molecules. Glycolysis is an oxygen dependent metabolic pathway.
