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.
Phosphorylase is an enzyme that adds a phosphate group to a molecule, typically to activate it. Phosphatase is an enzyme that removes a phosphate group from a molecule, usually to deactivate it or regulate its activity. Essentially, phosphorylase adds a phosphate group while phosphatase removes a phosphate group.

Which of the following statements about glycogen phosphorylase (GP) is incorrect?
AMP is an inhibitor of glycogen phosphorylase.
Why are both chloroplasts and mitochondria present in phosphorylase enzymes?
Chloroplasts and mitochondria both contain phosphorylase enzymes because these enzymes are involved in energy metabolism processes that occur in both organelles. Phosphorylase enzymes are responsible for catalyzing the breakdown of glycogen into glucose units in the cytoplasm, releasing energy in the form of ATP which is essential for cellular energy production.
What happens to acid phosphatase levels when prostate cancer spreads to other parts of the body?
When prostate cancer spreads to other parts of the body, such as the bones, the acid phosphatase levels may increase. Acid phosphatase is an enzyme that can be elevated in cases of bone metastasis from prostate cancer, as it is released by prostate cancer cells in the bones. Monitoring acid phosphatase levels can help in assessing the extent of metastasis and response to treatment.
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.)
Why is starch phosphorylase important in metabolism?
Starch phosphorylase is important in metabolism as it helps break down starch into glucose units for energy production. This enzyme plays a key role in glycogen degradation in animals and starch degradation in plants, providing essential substrates for energy metabolism. Additionally, starch phosphorylase helps regulate blood glucose levels and is involved in various cellular processes related to energy balance.
What is the difference between phosphorylase and phosphatase in terms of their functions and mechanisms of action?
Phosphorylase and phosphatase are enzymes involved in regulating cellular processes by adding or removing phosphate groups from molecules. Phosphorylase adds phosphate groups to molecules, while phosphatase removes phosphate groups. This difference in function affects how these enzymes interact with other molecules and influence cellular activities.
What is the difference between phosphatase and phosphorylase in terms of their functions and mechanisms of action?
Phosphatase is an enzyme that removes phosphate groups from molecules, while phosphorylase is an enzyme that adds phosphate groups to molecules. Phosphatase acts by hydrolyzing phosphate ester bonds, while phosphorylase catalyzes the transfer of a phosphate group from a donor molecule to a substrate molecule.
What are the differences between phosphatase, phosphorylase, and kinase in terms of their functions and mechanisms of action?
Phosphatase, phosphorylase, and kinase are enzymes involved in cellular processes. Phosphatase removes phosphate groups from molecules, phosphorylase adds phosphate groups to molecules, and kinase transfers phosphate groups from ATP to other molecules. Each enzyme has a specific function and mechanism of action in regulating cellular activities.
What is the difference between phosphorylase and kinase in terms of their roles in cellular signaling pathways?
Phosphorylase is an enzyme that adds phosphate groups to molecules, while kinase is an enzyme that transfers phosphate groups from ATP to other molecules. In cellular signaling pathways, phosphorylase helps activate or deactivate proteins by adding phosphate groups, while kinase helps transmit signals by transferring phosphate groups.
Phosphorylation of glycogen phosphorylase has what effect on the enzyme?
Activation, conversion from glycogen phosphorylase B to glycogen phosphorylase A
What is the difference between alpha 1,4 glucosidase and glycogen phosphorylase in terms of their roles in carbohydrate metabolism?
Alpha 1,4 glucosidase helps break down complex carbohydrates into simpler sugars, while glycogen phosphorylase helps break down glycogen into glucose for energy. Essentially, alpha 1,4 glucosidase is involved in the initial breakdown of carbohydrates, while glycogen phosphorylase is involved in breaking down stored glycogen for energy production.
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.
Which of the following statements about glycogen phosphorylase (GP) is incorrect?
AMP is an inhibitor of glycogen phosphorylase.
What is the difference between phosphorus and phosphatase?
Phosphorus is a chemical element found in many biological molecules such as DNA and ATP. Phosphatase is an enzyme that removes phosphate groups from molecules, playing a role in cellular signaling and metabolism. In summary, phosphorus is an element, while phosphatase is an enzyme that acts on phosphate groups.
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.
What are the differences in the functions and mechanisms of action between kinase, phosphatase, and phosphorylase enzymes in cellular signaling pathways?
Kinases add phosphate groups to proteins, activating them in cellular signaling pathways. Phosphatases remove phosphate groups, deactivating proteins. Phosphorylases break down glycogen into glucose for energy. These enzymes play key roles in regulating cellular processes through their actions on protein phosphorylation.
What is the substrate of phosphorylase?
The substrate of phosphorylase is glycogen. Phosphorylase is an enzyme that catalyzes the breakdown of glycogen into glucose-1-phosphate, which can then be used by cells for energy production.
