ATP is the main energy carrier in all organisms. Some organisms also GTP to great extent, but there really is not an organism that doesn’t use either ATP or GTP ultimately. Another carrier I know of that is frequently used is NADPH, which is not a nucleoside, but is structurally related.
Q. What are the uses of ATP?
ATP is consumed for energy in processes including ion transport, muscle contraction, nerve impulse propagation, substrate phosphorylation, and chemical synthesis. These processes, as well as others, create a high demand for ATP.

Q. What is the best example of chemical work?
What is the best example of chemical work? Lactate dehydrogenase reduces pyruvate to form lactate. Skeletal muscle contraction pulls on tendons and moves bones. H+ will diffuse across the inner mitochondrial membrane to provide the energy that powers the ATP synthase enzyme.
Q. What happens when glucose breaks down in absence of oxygen?
in the absence of oxygen in which glucose breaks into alcohol and carbon dioxide with release of energy. It takes place in yeast cells. Glucose –> ethanol + carbon dioxide + energy. In absence of oxygen in our muscle cells, Glucose breaks into lactic acid with the release of energy.
Q. What happens when glucose is broken down?
During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).
Q. Does glycolysis require oxygen?
Glycolysis requires no oxygen. It is an anaerobic type of respiration performed by all cells, including anaerobic cells that are killed by oxygen. For these reasons, glycolysis is believed to be one of the first types of cell respiration and a very ancient process, billions of years old.
Q. How does glycolysis occur in absence of oxygen?
Glycolysis converts a molecule of sugar into two molecules of pyruvate, also producing two molecules each of adenosine triphosphate (ATP) and nicotinamide adenine dinucleotide (NADH). When oxygen is absent, a cell can metabolize the pyruvates through the process of fermentation.
Q. Why does oxygen inhibit glycolysis?
Oxygen directly inhibits glyeolysis through its action on glyceraldehyde-3-P dehydro- genase, while N-ethylmaleimide appears to depress glycolysis by preventing efficient formation of ATP and, therefore, by indirectly inhibiting hexokinase and phosphofructokinase.
