Glycogen is a homopolysaccharide formed by units of glucose and is sometimes referred to as animal starch. It can reach up to a molecular weight of 10 to the power 8 DA which corresponds to about 600,000 glucose molecules.
The function of glycogen is that it is the principal form in which glucose is stored in animals and is present in the liver, muscle (skeletal and heart muscle) and in lower amounts in nearly all the other tissues and organs.
Glycogen makes up about 10% of liver weight and 1% of muscle weight. Although it is present in higher a concentration in the liver, the total amount stored in muscles is much higher due the greater mass of the muscles as compared to the liver.
Answer:
Option (D)
Explanation:
In terms of chemistry, a catalyst is usually defined as the substance that is commonly used in a reaction in order to increase the rate of reaction, without getting consumed. It helps in the reduction of activation energy.
In the given case, the lever or a person can be considered as a catalyst because both of these will increase the efficiency (or rate) in removing the rock from the top of the perch. Thus, the lever or the human will remain the same after the removal of rock as a catalyst can be recovered after the reaction.
Therefore, the correct answer is option (D).
A <span>peninsula is a "is a piece of land that is surrounded by water." Peninsulas are also known as islands because these are small pieces of land that are surrounded by water for example Hawaii, The Caribbean, etc...
