Phosphorylase adds the Phosphate group to substrate, but phosphatase takes off the Phosphate group from the substrate. the function of phosphorylase can be considered as same as kinase.
they are all playing key roles in the cellular signalling transduction via control the phosphorylation, the phosphatase can be the negative or positive regulator for different pathways. e.g. PTP1B dephosphorylates the JAK2 to suppress leptin in the hypothalamus that contribute to weight gain.

Which of the following statements about glycogen phosphorylase (GP) is incorrect?
AMP is an inhibitor of glycogen phosphorylase.
Example of enzyme responsible for a synthesis of a substance?
phosphorylase
Can glycogen be converted?
No. Insulin converts glucose into glycogen for storage in the body. Glucagon converts glycogen into glucose. (it's the various cells in the body that do the conversion in either case, insulin and glucagon are hormones that induce the shift in the metabolism.)
What happens to acid phosphatase levels when prostate cancer spreads to other parts of the body?
acid phosphatase levels rise, particularly if the cancer spreads to the bone. One-half to three-fourths of persons who have metastasized prostate cancer have high acid phosphatase levels
Who developed the acid phosphatase test for semen?
Frank Lundquist
What is the difference between phosphorus and phosphatase?
Phosphorus is a chemical element, while phosphatase is an enzyme used to remove chemical groups containing phosphorus, called phosphate gr oups, which are present in many bio molecules.
Phosphorylation of glycogen phosphorylase has what effect on the enzyme?
Activation, conversion from glycogen phosphorylase B to glycogen phosphorylase A
Which of the following statements about glycogen phosphorylase (GP) is incorrect?
AMP is an inhibitor of glycogen phosphorylase.
What are 5 specific enzymes?
Well this is a complicated question, one easy answer would be the salivary amylase, acetyl co enzyme A, B, C, D etc. 1) Each enzyme is specific : here are five out of 5,000 answers - - pyruvate decarboxylase - isocitrate lyase - acetyl-CoA transferase - phosphorylase kinase - tryptophan 2-3-dioxygenase 2) note that all enzyme suffixes are -ase. 3) phosphorylase kinase has two -ases - a nested loop - is an ON switch - phosphorylase phosphatase - also a nested loop - is an OFF switch.
What is phosphatase test in milk?
The phosphatase test in milk measures the amount of phosphatase enzyme in the milk. The phosphatase enzyme should be inactivated by pasteurisation. If the phosphatase test is not negative, there is a problem with pasteurisation or recontamination with unpasteurised milk.
Why is glycogen phosphorylase alone not sufficient in in degrading glycogen?
Glycogen phosphorylase can not cleave the alpha-1,6-glycosidic bonds at glycogen branch points
What is the last step in the sequence of events when cyclic AMP acts as a second messenger?
the last step is ofcourse glycogen breakdown.......before that inactive glycogen phosphorylase-b is activated and phosphorylated to glycogen phosphorylase-a by the help of activated phosphorylase kinase........ ......phosphorylase kinase was activated by activated protien kinase..and activated protien kinase was activated by cyclic amp...........
How is alkaline phosphatase testing performed?
Alkaline phosphatase is measured by combining the person's serum with specific substances with which alkaline phosphatase is known to react.this reaction is measured.the amount of alkaline phosphatase in the person's serum is determined.
What does alkaline phosphatase 207 do to body?
What causes the alkaline phosphatase to get to 158.
Example of enzyme responsible for a synthesis of a substance?
phosphorylase
What does the cleavage of glycogen phosphorylase release?
glucose-1-phosphate
Where is glucose-6-phosphatase located in liver cells?
glucose-6-phosphatase is not found in the liver. it is found in the muscles
