What is the substrate for Glycolysis?

generally glucose is the intial substrate in glycolysis .......

Sugars in the diet.  Next, would be gluconeogenesis from the liver.

In glycolysis, glucose eventually becomes pyruvate. Glucose and pyruvate are small molecules. The production of pyruvate does not happen at once: glucose first has a phosphate molecule attached to it, then it's oxygen bonds get tweaked a bit, then another phosphate gets attached... After ten small alterations, we have two pyruvates (glucose gets split in half along the line). The pathway starts with glucose and ends with pyruvate, but after the first step, it is not just glucose anymore, it is glucose-6-phosphate. After the second step it is fructose-6-phosphate. These molecules that are not the start or the finish of a pathway are called intermediates.\n\nAll the intermediates are small molecules. Enzymes are not small molecules (relatively speaking). Enzymes are proteins, the smallest of which are still hundreds of times more massive than glucose, pyruvate, and the glycolysis intermediates. Enzymes serve very specific functions and the transformation of glucose into the first intermediate of glycolysis is controlled by an enzyme. The transformation of the first intermediate into the second is also controlled by an enzyme (a different one). Just about every molecular transformation occuring in any organism is controlled by an enzyme. The enzymes do not change. They just cause the molecular transformation of other molecules to occur much faster than they would naturally.

atp phosphorylses the glucose to form glucose phosphate - this energises glucose and makes it more reactive, so that the subsequent steps of glycolysis (anaerobic respiration) are able to occur.\n\nif the glucose was not energised, it would not split into two to form triose phosphate, and would not form pyruvate (and therefore lactate) as it is not reactive enough.\n\n\nglycolysis reaction:\n\nglucose +atp => glucose phosphate + adp => 2triose phosphate  => 2 pyruvate\n\nThen NADH, a hydrogen carrier, supplies H+ ions to the pyruvate so it is converted into lactate.

C is false since NADH is produced during glycolysis as well as during the TCA cycle, unlike FADH2 which is prodcued only in the TCA cycle.  Remember TCA takes place in the mitochondria and glycolysis is in the cytosol.

Probably false.\nA cyclic pathway is more suitable for a starting material that is short in supply because the first molecule in the pathway tends to be regenerated. Glycolysis is the typical linear pathway and it starts with glucose which is relatively abundant in cells.\nI think this is not a very good question, though. It is open to interpretation.

E.  Your not going to hit the citric acid cycle or electron transport chain in an anaerobic environment so its not a or d.  B is impossible you can't just make more ATP during glycolysis.  I'm pretty sure when you oxidize pyruvate and NADH you just make Lactate and NAD.  The replenishing of NAD allows glycolysis to occur more quickly.

glycolysis-occur in the cytoplasm\nelectron transport chain-occur in the mitochondria\nkrebs cycle-occur in the mitochondria.\nif you consider mitochondria as part of the cytoplasm then all of the above..\nbut if not then it will be (a)

Glucose 6 phosphate is only immobilised by the attachment of the phophate group so that it cannot escape from the cell. Cells do not have the trasport machinery to export phosphorylated sugars. Further more, gluocse-6-phosphate formation does not guarantee glycolysis will continue, neither does the formation of F-6-P for that matter. This is because these intermediates can join pathways other than glycolysis. G-6-P for instance can join the Pentose Phosphate Pathway. So The G-6-P has to be oxidized to F-6-P and the F-6-P has to be reduced to F-1,6-bisphosphate. The F-1,6-BP formation is the committing step in glycolysis and hence naturally one of the regulation steps. It definitely will go into glycolysis. So oxidation of the intermediate G-6-P to F-6-P is needed and this has to be further oxidized to F-1,6-BP.

It is metabolism of the glucose energy by Reduction-Oxidisation (RedOx) reactions to be used in the electron transfer chain to produce Adeonsie Triphosphate (ATP) which is the basic energy unit that is used in cells.

==================================\nNAD+ is probably your answer.\n\nThe products of alcohol fermentation are:\nAlcohol (Ethanol) ATP, carbon dioxide \n\nSo you know for certain that your answer is either Pyruvic Acid or NAD+\n=======================\nI would argue that your teacher wants you to say NAD+ is NOT the by-product because NAD+ is converted to NADH.  Here's another way of looking at it:\n\nAlcohol fermentation is the formation of alcohol from sugar. Yeast, when under anaerobic conditions, convert glucose to pyruvic acid via the glycolysis pathways, then go one step farther, converting pyruvic acid into ethanol (alcohol).\n==============================

When you say activation energy I presume you're talking about the 2 ATP used? Those 2 ATP are part of the first step of aerobic respiration, glycolysis.\n\nIn glycolysis, we start with a molecule of glucose, C6H12O6\n1) 2 ATP are used\n2) 2 NADH are produced\n3) 4 ATP are produced\n4) 2 pyruvate are formed

It is more of a regulator enzyme than a catalyst. When there is a high concentration of ATP, the production of pyruvate is low, hence the slowing down of glycolysis (no more energy is needed).

glucose is fuel for the body.  glycolysis makes ATP which is essential for the body to function

fermentation is the process by which some types of microorganisms (like yiest) use monosacchaide (like glucose) as nutrint and porduce metabolite and CO2  by oxidising it partially and release partial energy.\nthe diff between glycolysis and fermentation is that -----\nin glycolysis glucose is fully oxidised and produce complete energy wich is greater than energy released in fermentation. moreover in fermentation carbohydrate is partially oxidised
