Intro to Biomolecules (Q&A)
QUESTIONS&ANSWERS to Bio-molecules
1) What is a macromolecule?
A. Its a type of large molecule that is essential for the cells of living organisms.
2) What are the for main types of macromolecules?
A. Lipids, Carbohydrates, and Nucleic Acid
3) What is a monomer?
A. Monomer is a single component that makes up macromolecules.
4) What is a polymer?
A. A polymer is a collection of monomers that are combined together.
5) What are the types of reactions that macromolecules are shown to undergo?
A. Macromolecules under hydrolysis reactions and and condensation reactions.
6) How monomers are joined together?
A. There joined together through the process of a condensation reaction.
7) How are polymers broken down?
A. Polymers are broken down through a process called hydrolysis.
8) What is the name for the bond formed between sugar monomers?
A. A covalent bond.
9) What kind of enzyme joins monomers together?
A. The polymerase enzyme is what joins monomers together.
10) How do you arrange sugar monomers to build polysaccarides?
A. I added a sugar molecule to another sugar molecule to form a glycosidic linkage. Then I added one more sugar molecule to those two sugar molecules. when I rotated it, I separate the hydrogen molecules so that the oxygen would connected to form H2O. After that the 4 molecules link together and I created a 4 molecule polysaccharide.
11) Which building blocks of macromolecules are not used in building carbohydrates?
A. Amino acids, fatty acids, and nucleotide are not used to build a carbohydrate.
12) Why is sugar stored as glycogen in the human body?
A. It is stored because it helps balance out the blood sugar level.
13) Why are plant foods essential in animal life?
A. The sugar and energy that are obtained through carbs comes from plants.
14) How is starch digested by animals?
A. The starch digestion starts at the mouth with the salivary amylase,then down into the small intestine. After that short chains of glucoses are broken down into individual glucose molecules that are absorbed.
15) What is fiber and why is it important in your diet?
A. Fiber is filament formed from vegetable tissue, mineral substance, or textile. It is important in our diet because it reduces the risk of cancer, diabetes, digestive disorder, and heart disease.
16) What causes you to pass gas(fart) according to the article?
A. Indigestable carbohydrates produce gas.
17) What are some disadvantages of a low-carb diet?
A. Possibility for cancer, lowered kidney/bone health, and loss in quality of life.
18) What role do sugars play in the formation of cavities on your teeth?
A. Sugars produces acids that cause cavities.
