Question

15+ POINTS!!!:

Answer 1

First off, this should be under bio not physics...

1) Dehydration synthesis. For proteins: When two single amino acids connect to form a larger dipeptide, the hydroxide group from one amino acid connects with a hydrogen from the other amino acid. This forms the biproduct of H2O, or water (The OH and H bond to form H2O). Dehydration synthesis DOES NOT only occur in proteins, it can occur in carbohydrates and other macromolecules as well.

2) Carbohydrates provide for short-term energy. They play a major role in cellular respiration.
Proteins serve many functions throughout your body. They can take the role of enzymes (speeding up and regulating reactions). There are also structural proteins that make up ligaments in your body. Finally, there are also defensive proteins, such as antibodies and signal proteins.
Lipids are more for long-term energy storage. Storing lipids is much more effective than storing carbohydrates. A single gram of lipids can store twice as much energy as a single gram of carbohydrates. Lipids (fats and oils) also serve to cushion your vital organs.

3) Cellulose and glycogen are usually very branched out. On the other hand, starch and sugars are usually unbranched; a single straight line.

Answer 2

1) I think the answer is polymerization but I'm not sure

2) Carbohydrates - provides energy for your body

Proteins do a lot of work in cells and exist for the structure, function, and regulation of the body's tissues and organs

lipids - are the main storage system/compounds that store the energy in your body


3)  I'm not exactly sure on this question, but I can tell you that cellulose, glycogen, and starch are all polymers of glucose but the differences are the types of bonds that they hold and the isomer type. For example, glycogen are compounds created from alpha-glucose. Also cellulose is created in plants.
