Answer:
1. Chain molecule made of many glucose molecules linked together-glycogen
Glycogen is the polysaccharide made up of monomer of D-glucose joined together by β(1-4) glycosidic linkage.
2. It serves as an energy source for the cell- adenosine triphosphate
ATP is produced by the oxidation of glucose molecule which contains a high energy phosphate bond. This phosphate bond breaks to provide energy to the cell.
3. A molecule which serves to make reactions work- enzyme
Enzymes are the molecules that catalyze a chemical reaction so it is helpful in increasing the speed of a chemical reaction and formation of the product.
4. Involves the production of ethyl alcohol from glucose- fermentation
In the fermentation process glucose is converted into alcohol and carbon dioxide in the absence of oxygen. Yeast is used to produce ethyl alcohol from glucose through fermentation.
5. A process in green plants which involves the use of the sun's energy- photosynthesis
Photosynthesis is the process by which plants and green algae makes their food with the help of CO₂ and H₂O in the presence of sunlight.
6. The first step in the chemical breakdown of glucose- glycolysis.
Glycolysis is the process of partial breakdown of glucose into 2 pyruvic acid. The glycolysis process is necessary to provide energy to the cell.
