What does glucagon do?
from what i know the function of glucagon is to convert glucogen into glucose when there is deficiency of glucose in the body where the glucogen is the access glucose which converted by the insulin
How is excess glucose stored in liver and muscle cells?
After a meal, as blood glucose rises, the pancreas is the first organ to respond. It releases the hormone insulin, which signls the body's tissues to take up surplus glucose. Muscle and liver cells use some of this excess glucose to build glycogen.
How do animal cells store glucose?
Once the body breaks down glucose it'll turn it into glycogen which stored in the muscles for about 2-3 hrs, however if u don't use it in that period the body will transformed it to triglyceride (body fat) and use later. Once ur body starts demanding energy it will retract glycogen or triglyceride and break it down and turn it into ATP.
How is glycogen and glucose structurally related to each other?
Ebo, Don't ask me I don't know too.
Which characteristic do glycogen and starch share?
They are both made up of chains of glucose molecules, with glycogen being the form for animals and starch being the form for plants.
Which group of organic moleculesincludes glycogen and glucose?
Glucose is an example of an organic compound that is classified as a monosaccharide. Other sugar molecules that are monosaccharaides are fructose and galactose.
What happens to the glucose when it is utilized by the body?
I am studying Bachelors of Science in Biotechnology and my Molecular biology lecturer asked me the question "Why is Glucose not stored in the body, but Glycogen is stored?"I couldn't answer her question in class...so i came home and "googled" and ofcourse i found the answer!Glucose is a ready source of energy, since its carbon atoms are easily oxidised to form carbon dioxide, releasing energy in the process ( so we now know why is glucose instant energy provider). Due to the numerous OH groups in glucose it readily hydrogen-bonds with water molecues, making it highly soluble in water. This allows easy transportation within the biological systems.If large amount of glucose was to remain in blood, the osmotic balance between the blood and the cell fluids would be disrupted and the cells would be damaged. However this does not occur, since the glucose does not remain in the bloodstream, but its converted into Glycogen in the liver. Glycogen is suitable for storage because it is insoluble and cannot pass through cell membranes.When glucose sugar is phosphorylated on carbon 6 we get glucose 6-Phosphate. its two major metaboilc pathways are:Glycolysis: If the cells need energy or carbon skeletons for sysnthesis then glucose 6-phosphate is targeted for glycolysis.Pentose phosphate pathway: when the ratio of NADP+:NADPH increses, the body realizes it needs to produce more NADPH. This will cause the G6P to be dehydrogenated by glucose 6-phosphate dehydrogenase. This reversible reaction is the initial step of the pentose phosphate pathway, which generates the useful co factor NADPH as well as Ribulose 5-phosphate, a carbon source for the synthesis of other molecules.If the blood sugar levels are high, the body needs a way to store the excess glucose. After being converted to G6P, an isomerase ( phosphoglucose mutase) can turn the molecule into glucose 1 phosphate. G1P can be combined with Uridine TriPhosphate (UTP) to form UDP-glucose, This reaction is driven by the hydrolysis of pyrophosphate that is released in the reaction. Now, the activated UDP-glucose can add to a growing glycogen molecue with the help of glycogen synthase. This is a very efficient storage mechanism for glucose as it requires only 1 ATP to store the 1 glucose molecule and virtually no energy to remove it from storage.Note that G6P is an allosteric activator of glycogen synthase, which makes sense because when the level of glucose is high the body should store the excess glucose as glycogen. On the other hand, glycogen synthase is inhibited when it is phosphorylated by protein kinase during times of high stress or low blood glucose levels.And when energy is needed by the body..glycogen is broken down into glucose and used up.I hope this explanation was enough! you can also visit these sites for more information.http://www.brianmac.co.UK/nutrit.htmhttp://www.carbs-information.com/glucose-energy.htmI hope this will help you!!Thankyou!Amukta!!
Can't we convert carbon dioxide into glucose?
i want to know that too. Whats your name.
An example of a polysaccharide that is used for energy storage in humans is?
STARCH in plants. GLYCOGEN in animals.
What does glucose do to your body?
i do not know becaus eall the sites talk about diabetes
What is a nonstrach polysaccharide?
Starch is a glucose polysaccharide that is bonded through alpha-linkage. Our body has an enzyme known as amylase which breaks these bonds and allows it to be digested by the body. Amylase is abundant in the mouth, which is why starch based products break down quickly as you chew them. A few examples of non-starch polysaccharides: Glycogen: A polysaccharide that consists of long chains of glucose, which as you may know, is a primary energy source for the body. It is stored in the liver. Cellulose: This is commonly known as dietary fibre, and is mostly indigestible. Our body does not have the enzymes required to break the beta-links in this glucose polysaccharide, which is why it passes through our system undigested.
How does exercise increase storage of glycogen and fat?
If the athlete had a fit rich and a poor carbohydrate diet, it would mean that they would have lower muscle glycogen content and a higher rate of fat oxidisation during exercise, when compared with a high carbohydrate low fat diet. The whole effect of such a diet could potentially be a sparing of muscle glycogen, and because muscle glycogen storage is paired up with endurance performance, it is possible that adaptation to a high fat diet could potentially enhance endurance performance. Therefor the athlete could afford to eat fatty things in their diet and be able to use the energy it gives to good use. The athlete would have to perform a lot of endurance exercise so that it does not hinder the performance.
