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.

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
