When a phosphate group is transferred directly from an intermediate to ADP to make ATP the process is called?
This process is called substrate-level phosphorylation. It occurs during glycolysis and the citric acid cycle, where a phosphate group is directly transferred to ADP to form ATP.
How many ATP are produced in the preparatory stage of glycolysis?
Two ATP molecules are produced in the preparatory stage of glycolysis. This occurs when glucose is split into two molecules of glyceraldehyde-3-phosphate.
Why is glycolysis rapid after infusion of fructose?
Fructose , after being absrobed ,goes through two pathways. Either it forms fructose-6-phosphate (by hexokinase) or it gets phosphorylated to fructose-1-phosphate by fructokinase found in liver.since liver contains much of he fructose obtained from diet fructose-1-phosphate is produced in appreciable amounts. Fructose-1-phosphate is acted upun by ALDOLASE B which breaks it into glecraldehyde and Dihydroxyacetone phosphate. both these enter glycolysis and since reactions catalyzed be hexokinase and epecially PFK-1 have been skipped in Fructose-1-phosphate metabolism hence glycolysis occurs faster ( PFK1 reaction is the main rate limiting step in glycolysis)
Where does glycolysis occur in animals cells?
Glycolysis occurs in the cytoplasm of animal cells. It is the first step in cellular respiration and does not require oxygen. Glycolysis breaks down glucose into two molecules of pyruvate, generating a small amount of ATP.
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.
In which step of glycolysis is an inorganic phosphate added?
The conversion of glyceraldehyde 3 phosphate to 1, 3 bisphosphoglycerate catalyzed byglyceraldehyde 3 phosphate dehydrogenase using NAD+ and Pi
When a phosphate group is transferred directly from an intermediate to ADP to make ATP the process is called?

How many ATP are produced in the preparatory stage of glycolysis?
Two ATP molecules are produced in the preparatory stage of glycolysis. This occurs when glucose is split into two molecules of glyceraldehyde-3-phosphate.
What are the required materials for glycolysis?
The required materials for glycolysis are glucose (sugar), ATP, NAD+ (nicotinamide adenine dinucleotide), and enzymes. The process of glycolysis occurs in the cytoplasm of cells and does not require oxygen.
What is the net profit in ATPs of glycolysis?
The net production of ATP in glycolysis is 2 ATP molecules. This occurs through substrate-level phosphorylation during the conversion of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate, and from phosphoenolpyruvate to pyruvate.
Which step in glycolysis is the entry point for galactose?
Glycolysis is the break down of glucose in pyruate and release of energy here are the steps in which glycolysis occurGlucose ------> glucsose-6-phosphate -------> fructose-6-phosphate --------> fructose-1,6-bisphosphate --------> glyceraldhyde-3- phosphate and dihydroxyactone phosphate now dihydroxyacetone phosphate isomerize in glyceraldhyde-3- phosphate ----------- 2 glyceraldhyde -3- phosphate ------------> 1,3-bisphosphoglycerate ---------> 3-phosphoglycerate ----------> 2-phosphoglycerate -----------> phosphoenolpyruate ----------- pyruatein these reactions during reaction 1 and 3 ATP are changed into ADP and so these are called energy consuming reactions and in 7 and 10th step 2 ATP are released in both steps so forming 4 ATP and in end giving net gain of 2 ATP. So in glycolysis fructose is consumed after isomerisation and phosphorylating in 2nd step, Fructose also enter directly in glycolysis in some species which use fruit sugar fructose which first convert in Dfructose which is then phorphorylated in fructose-6-phosphate
Process occurs in cytoplasm?
glycolysis, occurs in the cytoplasm
What is this process called when a ADP gains a phosphate and it becomes ATP?
The process of ADP gaining a phosphate group to form ATP is called phosphorylation. This occurs during cellular respiration, specifically in the mitochondria, where energy from nutrients is used to add a phosphate to ADP. This conversion is crucial for cellular energy storage and transfer.
What is the cellular region for glycolysis?
Glycolysis occurs in the cytoplasm.
What one of these stages occurs in the cytosol of the cell?
Glycolysis occurs in the cytosol of the cell. It is the metabolic pathway that breaks down glucose to produce energy in the form of ATP.
What Is the site of glycolysis?
Glycolysis occurs throughout the cytoplasm of the cell.
What is the anaerobic process that splits glucose into two molecules of pyruvic acid?
The anaerobic process that splits glucose into two molecules of pyruvic acid is called glycolysis. Glycolysis occurs in the cytoplasm of cells and is the first step in both aerobic and anaerobic respiration.
