A polymer is formed by linking of many monomers units by different kinds of bonds. In carbohydrates, this bond is a glycosidic bond. In the case of proteins, it is a peptide bond. In nucleic acids, the bond is an ester linkage. The monomers link together by two mechanisms: addition polymerization, or condensation polymerization.
Answer:
The cholecystokinin hormone is the one responsible for releasing the bile from gallbladder.
Explanation:
The cholecystokinin hormone is produced from cells in the duodenum (a part of the small intestine). When we eat food rich in fats, this enzyme stimulates the contraction of gallbladder to release the bile. Additionally, this enzyme stimulates other areas of the gastrointestinal system (pancreas and liver) to digest fat, proteins and carbohydrates and also is responsible for reducing appetite while we are eating. The persons who have little cholecystokinin have problems in digesting fats and also is related to obese people.
If a person uses up his or her reserve supply of glycogen and still does not eat, sugar comes from the muscle.
Although only liver glycogen directly contributes to the release of glucose into circulation, maintaining a healthy blood glucose concentration is one of the glycogen's key functions. Since skeletal muscles lack glucose 6-phosphatase, they are unable to release glucose, and muscle glycogen primarily serves as a local energy source for activity rather than a source of fuel to keep blood glucose levels stable while fasting.
In fact, the breakdown of muscle glycogen into lactate allows for its delivery to the liver, where it participates in the maintenance of euglycemia through the process of gluconeogenesis (Cori cycle).

Sunlight provides energy needed for photosynthesis
Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal elements.
