Final answer:
The correct answer is E) both the pentose phosphate and Entner-Doudoroff pathways. The pentose phosphate pathway generates NADPH, which is important for cellular processes. The Entner-Doudoroff pathway converts glucose to ethanol and produces one ATP.
Step-by-step explanation:
The correct answer is E) both the pentose phosphate and Entner-Doudoroff pathways.
The pentose phosphate pathway (PPP), also known as the phosphogluconate pathway or the hexose monophosphate shunt, is a metabolic pathway that occurs parallel to glycolysis. It generates NADPH, which is used in various cellular processes including the synthesis of nucleotides and amino acids. The Entner-Doudoroff pathway (ED pathway) is another type of glycolytic pathway that occurs in all cells. It converts glucose to ethanol and produces one ATP. Although it is not as common as the other glycolytic pathways, it is still important for some organisms.
