One way to test a mineral is to break it and see how many directions of what it has?
cleavage....
What is the cleavage of dolomite?
Dolomite typically exhibits three cleavage planes that intersect at approximately 90 degrees, resulting in rhombohedral cleavage.
Does galena have a cleavage or a fracture?
Galena has a distinct cleavage, typically showing cubic cleavage planes.
What is the cleavage of muscovite?
Muscovite has perfect basal cleavage, meaning it cleaves easily along one plane into thin sheets. This cleavage is due to the arrangement of the mineral's atoms in its crystal lattice.
What is a sentence for cleavage?
The actress wore a low-cut dress that showed off her cleavage.
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.
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 main enzyme for breaking down glycogen?
The main enzyme for breaking down glycogen is glycogen phosphorylase. This enzyme catalyzes the phosphorylytic cleavage of glucose residues from the glycogen polymer, releasing glucose-1-phosphate for energy production.
Does Glycogen has more accessible cleavage sites than amylose?
Yes, glycogen has more accessible cleavage sites than amylose because it is a highly branched polymer with multiple alpha-1,6-glycosidic bonds in addition to alpha-1,4-glycosidic bonds. This branching structure allows for more points of cleavage by enzymes like glycogen phosphorylase compared to the linear structure of amylose.
Which enzymes are required for glycogen breakdown?
glycogen phosphorylase, glycogen debranching enzyme, phosphoglutomutase
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...........
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.
What enzyme regulates glycogenolysis?
Actually, three are the enzymes that intervene during glycogen breakdown (glycogenolysis).First, Glycogen phosphorylase (or simply phosphorylase) that catalyzes glycogen phosphorolysis (bond cleavage by the substitution of a phosphate group) to yield glucose-1-phosphate (G1P) releasing only one glucose residue that is at least five residues from a ramification point.The second enzyme is the Glycogen debranching enzymethat removes glycogen's branches, thereby permiting the glycogen phosphorylase reaction (see above) to go to completion. This enzymes also hydrolyzes alpha(1-6)-linked glucosyl units to yield glucose.Finally, Phosphoglucomutase that converts G1P to G6P which is also formed in the first step of glycolysis through the action of either hexokinase or glucokinase.
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.)
How is glycogen broke down?
Glycogen is broken down through a process known as glycogenolysis, which involves the breakdown of glycogen into glucose molecules. This process is mainly controlled by enzymes such as glycogen phosphorylase and glucose-6-phosphatase. The resulting glucose is then available for energy production or storage in the body.
What are the three enzymes involved in the conversion of glycogen to glucose?
The process of "glycogenolysis" is the splitting of glycogen in the liver, which in turn produces glucose. Glucagon can be administered in emergency diabetic situations where sugar can't be taken orally.
