What else can I help you with?
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?
It has both. It's cleavage is perfect, and it's fracture is sub-conchoidal.
What is the cleavage of muscovite?
Muscovite has perfect basal cleavage, or book cleavage.
What is a sentence for cleavage?
Cleavage is, essentially, a split in something. An example sentence would be: The cleavage in the mountain is actually a bit concerning.
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.
Which enzymes are required for glycogen breakdown?
glycogen phosphorylase, glycogen debranching enzyme, phosphoglutomutase
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.
What breaks down glycogen in the body?
The enzyme called glycogen phosphorylase breaks down glycogen in the body.
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 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 is the substrate of phosphorylase?
The substrate is Glucose-1-phospate which is broken down by only Phosphorylase and produces Starch as its end product
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.)
