Cellular Respiration
1. Describe the relationship between cellular respiration, ADP, ATP and cellular work

Cellular respiration makes ATP by joining phosphate groups to ADP to make the ATP. ATP can easily be put together by taking ADP and adding phosphate. Energy release from ATP can be recycled by the cell to make new ATP. ATP powers work in cells. An example would be that food energy must be converted into ATP. Cellular respiration generates ATP for cellular work.

2. Compare the end products of cellular respiration and fermentation
The end products of Cellular respiration are water and carbon dioxide as its waste products. Fermentation end products are Carbon dioxide and Ethanol.

3. Compare the alcoholic fermentation of glucose, sucrose and starch

4. Define the following terms:
Carbohydrates: member of the class of biological molecules consisting of single –monomer sugars (monasaccharides), two-monomer sugars (disaccharides), and polymers (polysaccharides).

Proteins: a functional biological molecule consisting of one or more polypeptides folded into a specific three-dimensional structure.

Fats: a lipid composed of three fatty acids linked to one glycerol molecule; a triglyceride. Most fats function as energy-storage molecules

High-energy phosphate bonds: Energy-rich phosphate linkages present in adenosine triphosphate (ATP), phosphocreatine, and certain other biological molecules

ADP: Adenosine diphosphate, composed of adenosine and two linked phosphate groups, that is converted to ATP for the storage of energy

ATP: adenosine triphosphate, the main energy source of cells

Cellular respiration: the aerobic harvesting of energy from food molecules; the energy-releasing chemical breakdown of food molecules, such as glucose, and the storage of potential energy in a form that cells can use to perform work; involves glycosis, the citric acid cycle, and oxidative phoshorylation (the electron transport chain and chemiosmosis)...
