Where in the cell does glycolysis occur? A. on the outer mitochondrial membrane B. in the endoplasmic reticulum C. in the cytoplasm D. in the fluid of the mitochondria

Why do cells go to the trouble of making ATP when they already have glucose molecules? A. glucose holds too much energy; ATP is easier to spend on cell work B. an ATP molecule holds more energy than a glucose molecule C. prokaryotes cannot use glucose at all, so they must make ATP D. because eukaryotes are complex, they must complicate all chemical reactions
