Question

1. polymers are made up of chains of a. monosaccharides b. nucleotides c. amino acids d. fatty acids e. steroids 10. what type of reaction breaks the carbohydrate in your food into monomers during digestion? a. hydrolysis b. synthesis c. exothermic d. exergonic e. none of the above open ended questions 1. explain the relationship between monomers and polymers, using polysaccharides as an example. 2. what type of food will you eat before going on a marathon race and why did you choose this food? 3. why must we include lipids in our diet even though they say it is bad for our health? 4. what is the function of nucleic acids? what are the two types of nucleic acids? 5. write at least 2 important reasons why protein should be included in our diet

Explanation:

1. Proteins are made up of chains of amino - acids. Amino - acids are the building blocks of proteins.
2. Hydrolysis is the type of reaction that breaks carbohydrates into monomers during digestion. It involves the addition of water to break chemical bonds.
3. Monomers are single units that join together through chemical bonds to form polymers. In the case of polysaccharides, monosaccharides (such as glucose) are the monomers that link together to form the polysaccharide polymer.
4. Before a marathon, one might eat complex carbohydrates like whole - grain pasta or bread. Complex carbohydrates are broken down slowly into glucose, providing a sustained release of energy during the long - distance run.
5. Lipids are important in the diet as they are a concentrated source of energy, and they are also needed for the absorption of fat - soluble vitamins (A, D, E, K).
6. Nucleic acids (DNA and RNA) store and transmit genetic information. The two types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
7. Protein should be included in the diet because it is essential for growth and repair of tissues (such as muscles, skin, and organs), and it also plays a role in the production of enzymes and hormones.

Answer:

1. c. Amino acids
2. a. Hydrolysis
3. Monomers are single units that form polymers. For polysaccharides, monosaccharides are monomers.
4. Complex carbohydrates like whole - grain pasta or bread for sustained energy.
5. Lipids are a concentrated energy source and aid in fat - soluble vitamin absorption.
6. Nucleic acids store and transmit genetic info. Types are DNA and RNA.
7. For growth/repair of tissues and enzyme/hormone production.
