Glucose is called a 6 carbon sugar because there are six carbon atoms along its back bone, which are either attached to a hydrogen in one side and a hydroxyl group (OH) to the other side. the very fist carbon i attached to a hydrogen by a single bond, and to an oxygen by a double bond, while your last carbon besides being attached to the hydrogen and hydroxyl group it also has another hydrogen attached to it. All are attached by single bond with the exception of that one oxygen.

What are the three carbon molecules when glucose is broken in half during glycolysis?
The 3-carbon molecule produced when glucose is broken in half in glycolysis is pyruvic acid. It gives energy to living cells through the Krebs cycle.
What cycle produces a three carbon sugar?
In turning Glucose to a 3 carbon sugar, it is called glycolysis.
The series of chemical reactions in which a molecule of glucose is broken down is called?
The part of cellular respiration in which glucose is broken down is called the glycolysis. The chemical energy to produce ATP come from the breakdown of carbon based molecules into the smaller molecules.
How many pyruvate molecules are produced per glucose molecule during glycolysis?
Glucose contains six carbon atoms, whereas pyruvate only contains three, so it is possible to derive two pyruvate molecules (3+3 carbon atoms) from one glucose molecule (=6 carbon atoms). During the early stages of glycolysis, the glucose is converted into Fructose-1,6-bisphosphate. This molecule also has six carbon atoms, and is split by an enzyme called 'fructose biphosphate aldolase' into two separate molecules containing three carbon atoms: glyceraldehyde-3-phosphate and dihydroxyacetone phosphate. It is the glyceraldehyde-3-phosphate that is later converted into pyruvate, accounting for the first pyruvate molecules from glucose. However, the other 3-carbon molecule, dihydroxyacetone phosphate, is kept in equilibium with glyceraldehyde-3-phosphate by an enzyme known as 'triose phosphate isomerase', so that this is eventually converted into pyruvate as well. The result being two pyruvate molecules per glucose molecule.
What substance is oxidized during cellular respiration?
Glucose is. In cell respiration, the carbon atoms of glucose are oxidized.
How is glucose changed during glycolysis what products are produced as a result of glycolysis?
Glycolysis is the process during which glucose is broken in half, and produces pyruvic acid (3-carbon compound)
What are the three carbon molecules when glucose is broken in half during glycolysis?
The 3-carbon molecule produced when glucose is broken in half in glycolysis is pyruvic acid. It gives energy to living cells through the Krebs cycle.
Raw materials needed for glycolysis?
Glycolysis is inherent in the process of respiration. The cell requires glucose and oxygen during glycolysis and water is the by-product
Is any co2 produced during glycolysis?
Yes. Two carbon dioxide molecules for each molecule of glucose entering glycolysis.
Why are monosaccharides immediately phosphorylated upon entry into cells?
One example of modified monosaccharides are the phosphorylated sugars. An important phosphorylated sugar is glucose 6-phosphate, which is a glucose phosphorylated on carbon 6. The significance of this molecule is that it provides energy in certain metabolic pathways, and it can be converted and stored as glycogen when blood glucose levels are high. If blood glucose levels are low, glucose 6-phosphate can be converted back into glucose to enter the bloodstream once again. A unique property of glucose 6-phosphate is that once glucose is phosphorylated, the sugar possesses a negative charge. This prevents the molecule from leaving the lipid-bilayer membranes. This allows the cell to easily access the modified sugar to provide energy for metabolic pathways such as glycolysis, or convert it to glycogen as storage.
Why Hexokinase phosphorylated the glucose at first step of glycolysis?
The first step in glycolysis is catalyzed by hexokinase, an enzyme with broad specificity that catalyzes the phosphorylation of six-carbon sugars. Hexokinase phosphorylates glucose using ATP as the source of the phosphate, producing glucose-6-phosphate, a more reactive form of glucose.
Does eighty percent of the energy generated during the catabolism of glucose to carbon dioxide and water occur during glycolysis?
80%
What is a 3 carbon molecule produced when glucose isbroken in half during glycolysis?

glucose
What six carbon molecule begins glycolysis?
glucose
