The cell has a variety of other pathways that can make oxaloacetate (the final 4 carbon product in the krebs cycle) from other molecules in the cel Why might these alternative pathways be important? 7. The Krebs cycle is a circle. What do you think would happen if you removed one of theExplanation / Answer
1) Glycolysis is the process in which glucose splits to form pyruvate and provides energy to the cell. Glucose is the simplest form of carbohydrate. This provides energy to the cell. The first step of glycolysis occurs in the cytoplasm of the cell and second step occurs in the mitochondria of the cell. Hence, the starting substance of glycolysis is glucose and the product obtained from glycolysis is pyruvate
2) Gycolysis takes place in the cytoplasm of the cell
3) One redox reaction occurs during glycolysis. It occurs durig oxidation of glucose.
It occurs during the formation of 1,3 bis phosphate from Glyceraldehyde 3 phosphate, in which NAD+ accepts the electron and gets reduced to form NADH.
4) Two ATP are used during glycolysis. Four ATP are produced during this process. The output of ATP during glycolysis is two.
Her 2 ATP is needed to start the glycolysis process and two pyruvate are produced which gives 2*2=4 ATP.
Thus the total output is (4-2)=2
