PPT-GLYCOLYSIS Glycolysis is the breakdown or catabolism of a six carbon glucose molecule

Glycolysis occurs in ten steps and in two phases The first 5 steps constitute the PREPARATORY PHASE in which the energy of 2 ATP is invested raising the freeenergy content of the intermediates and the carbon chains of all the metabolized hexoses are converted into a common product glyceraldehyde3phosphate . WOW do I Need Energy . ATP. All cells need energy. The most common form of cellular energy is ATP. Below is ATP. It is the negative phosphate groups that give this molecule energy as it becomes unstable. When the phosphate is transferred to other molecules, those molecules have energy because they become unstable.. Chapter 6. What is ATP? . Analogy with the coins and the bending machine . How does it function like a rechargeable battery? . RECHARGING ATP. Occurs in the Mitochondria . How do we obtain the energy from GLUCOSE to make ATP? . Glycolysis . is the breakdown or catabolism of a six carbon glucose molecule in a series of enzyme catalyzed reactions to give 2 molecules of pyruvate which is a 3 carbon compound. Glycolysis takes place in all the cells in the cytosol . During the sequential reactions of glycolysis some of the free energy is stored in the form of ATP and NADH. . Glucose in the bloodstream enters our cells, where it undergoes degradation in a pathway called glycolysis. . Glucose obtained from the digestion of polysaccharides is degraded in glycolysis to pyruvate.. 1. How . many NADH are produced . . in . glycolysis per glucose?. (a) 1. (b) 2. (c) 4. (d) 8. 2.

Glycolysis is the first step in the breakdown of glucose to extract energy for cellular metabolism. Glycolysis consists of an energy-requiring phase followed by an energy-releasing phase.. 1.
