How many pyruvic acid are formed during glycolysis?
The enzymes of glycolysis catalyze the splitting of glucose, a six carbon sugar, into two three carbon sugars. These are then oxidized and their atoms rearrangged to form two molecules of pyruvic acid
How a solution is formed?
A solution is formed as individual molecules from the solid are surrounded by molecules of solvent and then diffusing away from the surface of the solid being dissolved.
What is a hypothetical four stage sequence for how life could have first developed on Earth?
firstly small organic molecules formed from simple molecules.secondly these small molecules joined together into proteins and nucleic acids.thirdly molecules that could copy themselves such as RNA provided a way for molecular information to be inherited.fourthly,various organic molecules such as RNA and polypeptides formed "pre cells"
Which bond type is formed between two polar molecules that contain hydrogen?
a hydrogen bond
How is a molecule formed?
Molecules are formed when atoms lose electrons and then attach themselves to other atoms
How many ATP molecules are produced per molecule of glucose during glycolysis?
In glycolysis two net molecules of ATP are formed. Four ATP are formed but two are required in the initial activation of glucose.
Is Pyruvate is a product of glycolysis?
Yes. Pyruvate is a product of glycolysis. This molecule contains three carbons. For every molecule of glucose that enters the glycolytic pathway, two molecules of pyruvate are formed
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 happens to the molecules formed during glycolysis?
The reaction varies under oxidizing vs un-oxidizing conditions. In one, the molecule ADP is produced with other molecules and gives muscles their energy. under reducing condition the result is ketone.
Why are only two molecules of NADH formed during glycolysis when it appears that as many as a dozen could be formed?
Only two molecules of NADH are formed during glycolysis because NAD+ is only reduced to NADH in the steps where glyceraldehyde-3-phosphate is converted to 1,3-bisphosphoglycerate. The other steps of glycolysis don't involve a direct reduction of NAD+ to NADH.
How many molecules of ATP are gained by substrate-level phosphorylation from the complete breakdown of a single molecule of glucose in the presence of oxygen?
In substrate level phosphorylation, the ADP is phosphorylated directly by the transfer of phosphate group from substrate. If we consider glucose, then we get four substrate level phosphorylated ATPs, net gain of two in glycolysis and other two are formed when the two pyruvate molecules formed after glycolysis enter the TCA cycle.
Where is Glyceraldehyde 3-phosphate produced?
Glyceraldehyde 3-phosphate is produced during the process of glycolysis in the cytoplasm of cells. It is formed from the breakdown of glucose into pyruvate through a series of enzymatic reactions.
How much energy is needed to start the process of glycolysis?
Two molecules of ATP are needed to start the process of glycolysis. These ATP molecules are used to prime the glucose molecule for further breakdown and energy production.
What happens to pyruvate molecules formed glycolysis in the absence of oxygen?
they will enter the Krebs cycle
Is ADP a product of glycolysis?
No, ADP (adenosine diphosphate) is not a direct product of glycolysis. In glycolysis, glucose is broken down into pyruvate, generating ATP (adenosine triphosphate) as an energy carrier. ADP is formed when ATP loses a phosphate group, releasing energy for cellular processes.
What must happen before acetyl can be formed during respiration?
Glycolysis
What is the total number of ATP molecules formed during celluar respiration?
The total number of ATP molecules produced during cellular respiration varies depending on the efficiency of the process and the type of organism. In general, aerobic respiration can yield up to 38 molecules of ATP per molecule of glucose, while anaerobic respiration produces a smaller amount, around 2 molecules of ATP per molecule of glucose.
