A phosphate group is transferred from ATPstart text, A, T, P, end text to glucose, making glucose-6-phosphate. Glucose-6-phosphate is more reactive than glucose, and the addition of the phosphate also traps glucose inside the cell since glucose with a phosphate can't readily cross the membrane.

Calculate the amount of fructose 6 phosphate formed from glucose 6 phosphate in a 10 milliliter incubation system if 0.5M G6P is incubated overnite at 25oC and the equilibrium constant is 0.67.
Reaction: Glucose-6-P ----gt; Fructose-6-P 0,5 M 0 x x 0,5 - x x For the following reaction expression of the equilibrium constant is: K=0.67= x/(0.5-x) X = 0.2 n (Fructose-6-P)...

what are the materials needed for glycolysis and what are the products of glycolysis?
Resources for glycolysis: most monosaccharides, such as fructose, glucose, and galactose At the end of glycolysis, each molecule of glucose has yielded 2 molecules of pyruvate, 2 molecules of NADH,...

How does the role of glucose-6-phosphate in gluconeogenesis differ from that in glycolysis? (4 marks)
One of the steps that differs gluconeogenesis fromglycolysis is the conversion of glucose-6-P to glucose with the enzymeglucose-6-phosphatase. This enzyme islocated in the endoplasmic reticulum. The amounts and activities of...

What is the difference between an enol phosphate ester and a normal phosphate ester that gives PEP such a high phosphoryl group transfer potential? ( 3 marks)
PEP has high phosphoryl transfer because the phosphoryl group traps PEP into its unstable enol form. Once the phosphate group is transferred to ATP, the enol converts to a more...

Addition of Phosphate groups to molecules usually requires ATP as source of energy but in glycolysis a phosphate group is added to Glyceraldehyde-3-P without a ATP molecule. How?
Glyceraldehyde-3-P (GAP) is also known as triose phosphate. ATP molecule is not required when adding a phosphate group to Glyceraldehyde-3-P since the triosephosphate isomerase enzyme rapidly transforms the molecules so that...

If the product of photosynthesis are used to make glucose and glucose is used for glycolysis, this means that molecules are moving between which two compartments in the cell?
If the product of photosynthesis are used to make glucose and glucose is used for glycolysis, this means that molecules are moving between chloroplasts and cytoplasm.

Can you please explain the difference in the pathway between ANAEROBIC glycolysis and AEROBIC glycolysis? Also do you know what substrates would be involved in each?
The difference between aerobic glycolysis and anaerobic glycolysis is that aerobic glycolysis proceeds in the presence of oxygen and occurs in eukaryotic cells while anaerobic glycolysis proceeds in the absence of...

An aqueous solution of sodium phosphate is a 0.142 M Na3PO4(aq) has a density of 1.02 g/ml What is the percent by mass of sodium phosphate ? What is the mole fraction of sodium phosphate
The percent mass of Na3PO4 in this solution we can determine, using following equation:w = C×M(Na3PO4) / (10×p), where C is molar concentration; M is molar mass of sodium phosphate;...
