WebSubstances can diffuse in and out at a high rate and easily reach all parts of the cell. Because of their smaller surface area: volume ratio, larger organisms need transport … WebThe process does not use oxygen and is therefore anaerobic. Glycolysis takes place in the cytoplasm of both prokaryotic and eukaryotic cells. Glucose enters heterotrophic cells in two ways. One method is through secondary active transport in which the transport takes place against the glucose concentration gradient.
