Glycolysis begins with glucose and produces two pyruvate molecules, four new ATP molecules, and two molecules of NADH. (Note: two ATP molecules are used in the first half of the pathway to prepare the six-carbon ring for cleavage, so the cell has a net gain of two ATP molecules and two...
6. The pentose phosphate pathway primarily produces: A. ATP and NADH B. Ribose 5-phosphate and NADPH C. Pyruvate and ATP D. Glucose and NADH Answer: B 7. Which enzyme acts as the main regulatory point in glycolysis? A. Hexokinase B. Phosphofructokinase-1 (PFK-1) C. Pyruvate kinase D...
glucose c. lactic acid d. ATPAcetyl-CoA is used during: a) the electron transport system. b) glycolysis. c) fermentation. d) the Krebs cycle..The metabolic cycle that begins with the molecule Acetyl CoA and produces most of the NADH and...
This reaction series begins with a single glucose molecule to produce a net of 2 ATP, 2NADH, and 2 pyruvate molecules. It marks the beginning of many catabolic reaction series like aerobic and anaerobic respiration. Answer and Explanation: The rate of glyc...
T2D normally presents in later adult life and is a progressive disease that begins with impaired glucose tolerance and advances to diabetes as β-cells gradually fail. By the time of diagnosis as much as 50% of β-cell function has been lost1. There is accumulating evidence that β-cell ...

the glucose on through the bloodstream or store the excess glucose asglycogen. Cells in the body take up the circulating glucose in response to insulin and through glycolysis, transferring some of the energy in glucose to ADP to formATP. The last step in glycolysis produces the productpyruvate....
Aerobic glycolysis is operational in cells with high demand for rapid energy production and biosynthesis, since glycolysis provides ATP at a faster pace compared with the TCA cycle, at the expense of inefficient and increased consumption of glucose. Macrophage activity against pathogens and tumor cells...
Glycogen/glucose metabolism (Fig. 151.1) Anaerobic glycolysis is the main metabolic pathway used in the setting of limited oxygen supply during exercise. It is used during high-intensity, sustained, isometric muscle activity.1 It is inefficient from an energetic standpoint and produces only two ATP...
Figure 3. The second half of glycolysis involves phosphorylation without ATP investment (step 6) and produces two NADH and four ATP molecules per glucose. Step 6. The sixth step in glycolysis (Figure 3) oxidizes the sugar (glyceraldehyde-3-phosphate), extracting high-energy electrons, which are...
