What molecule supplies the energy needed to join glucose molecules together to form a molecule of glycogen?
Generally speaking, no molecule supplies the energy to join a glucose into a growing glycogen chain. A previous step must be done and that is the formation of uridine diphosphate glucose (UDP-glucose or UDPG). Since the direct conversion of Glucose 1 phosphate (G1P) to glycogen and Pi is thermodynamically unfavorable (positive delta G) under all physiological Piconcentrations, glycogen biosynthesis requires the formation of UDPG by the combination of G1P with uridine triphosphate (UTP). UDPG's "high energy" status permits it to spontaneously donate glucosyl units to the growing glycogen chain. The step is catalyzed by the enzyme Glycogen Synthase, the glycosyl unit of UDPG is transferred to the C4-OH group on one of the glycogen's nonreducing ends to form an alpha(1-4)-glycosidic bond.
What else can I help you with?
Why are complex carbohydrates better for storing energy than simple sugar?
Simple sugar molecules will create lot of osmotic pressure in the cell. In case of glycogen, you have thousands of glucose molecules put together. Glycogen molecule is compact and does not produce much osmotic pressure.
Does glycogen polymer contain nitrogen?
No, glycogen is a complex carbohydrate composed of glucose molecules linked together. It does not contain nitrogen.
What like glycogen and starch are made by joining many sugar molecules together?
glucose
Why is glycogen soluble?
Glycogen is soluble because it is composed of many glucose molecules linked together in a branched structure. These glucose molecules are hydrophilic, meaning they are attracted to water and can readily dissolve in it. This solubility allows glycogen to be stored in cells and readily broken down to release glucose when needed for energy.
The chemical process of building glycogen from glucose molecules?
Glycogen is synthesized by the enzyme glycogen synthase, which adds glucose molecules together to form a long chain of glycogen. This process requires energy in the form of ATP and occurs primarily in the liver and muscles when blood glucose levels are high. Glycogen serves as a storage form of glucose for the body to use when needed.

What proteins lipids and glycogen have in common?
Large molecules that contain carbon and are held together by covalent. They are the structural units of glycogen.

What is the subunits of glycogen?
Glycogen is composed of individual glucose molecules linked together in chains. The subunits of glycogen are alpha-glucose molecules connected by alpha-1,4-glycosidic bonds with occasional alpha-1,6-glycosidic bonds forming branches.

Atoms bonded together to form a chemical unit are called?
Molecules
An example of a large carbohydrate molecule is?
Some examples could be glycogen, cellulose, or starch.
What is the process of making glycogen?
Glycogen is made through a process called glycogenesis, which involves converting excess glucose molecules into glycogen for storage in the liver and muscles. This process is facilitated by enzymes such as glycogen synthase, which link glucose molecules together to form glycogen chains. Glycogen can be broken down back into glucose through a process called glycogenolysis when the body needs energy.
What are common plysacchride?
Carbohydrates (e.g., starch, cellulose, or glycogen) whose molecules consist of a number of sugar molecules bonded together.
