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...
Glycolysis ___. (a) releases all of the chemical energy in the original glucose molecule (b) occurs in mitochondria (c) produces two molecules that contain much of the chemical energy in the original glucose molecule (d) does not produce a...

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 ...
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 form ATP. The last step in glycolysis produces the product pyruvate. Lipids in Cellular Respiration Ketones in Cellular Respiration Lesson Summary...
Which of the three main stages of aerobic cellular respiration provides the biggest payoff of ATPs, and about how many ATPs are produced from one glucose during this stage?The metabolic cycle that begins with the molecule Acetyl CoA and produces most ...
. 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 ...
Cellular respiration: Cellular respiration occurs in living organisms to breakdown glucose and generate ATP energy needed by the cells. This process occurs aerobically in three steps: glycolysis, citric acid cycle and the electron transport chain. ...
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...
