Glycolysis - Chemistry Encyclopedia - structure, molecule
Therefore, in the majority of cells the most important function of glycolysis is to metabolize glucose to generate three-carbon compounds that can be utilized by other pathways. Although the glycolytic pathway is most commonly thought of as metabolizing glucose, other common monosaccharides such as fructose, galactose , and mannose are also metabolized by it
BC Online: 8C - ATP and Ox-Phos Reactions
The DGo for hydrolysis of ATP is dependent on the divalent ion concentration and pH, which affect the the stabilization and the magnitude of the charge states of the reactants and products. The charge density on the reactants is greater than that of the products Theoretical studies show that the products are more hydrated than the reactants
Types of exercise (EUFIC)
This helps our bodies more efficiently deliver oxygen to muscles, can improve overall circulation and reduce blood pressure and remove irritating metabolic waste products such as lactic acid from the muscles. Both aerobic and anaerobic exercise also work to increase the mechanical efficiency of the heart by increasing cardiac volume (aerobic exercise), or myocardial thickness (strength training)
Molecules derived from the breakdown of fats, proteins, and carbohydrates can enter glycolysis or the Krebs cycle at various points in order to yield more energy to an organism. Part A How does oxygen get into or out of chloro- plasts and mitochondria? Part B What are the roles of oxygen in the processes of photosynthesis and cellular respiration, and how are the roles similar? Make sure you get plenty of rest the night before the test
Beyond aerobic glycolysis: Transformed cells can engage in glutamine metabolism that exceeds the requirement for protein and nucleotide synthesis
Together, the data imply that at citrate synthase, the majority of acetyl-CoA is derived from glucose, whereas the majority of OAA is derived from glutamine. In these cells, the tricarboxylic acid (TCA) cycle was active but was characterized by an efflux of substrates for use in biosynthetic pathways, particularly fatty acid synthesis

Alcoholic Fermentation Another route to NAD+ produces alcohol (ethanol) as a by-product: pyruvate + NADHethyl alcohol + NAD+ + CO2 Alcoholic fermentation is the source of ethyl alcohol present in wines and liquors. The Krebs cycle is called a cycle because one of the molecules it starts with, the four-carbon oxaloacetate, is regenerated by the end of the cycle to start the cycle over again
In the oxidative system the resynthesis of ATP happens at a much slower rate, but we can maximize the number of ATPs produced, yielding us with the highest amount of energy.

In 1856, a man named Bigo sought Pasteur's help because he was having problems at his distillery, which produced alcohol from sugar beetroot fermentation. In contrast, in the polluted containers, the ones containing lactic acid, he observed "much smaller cells than the yeast." Pasteur's finding showed that there are two types of fermentation: alcoholic and lactic acid
