3.2 and 3.3 SG

Question 1

Low Level- Monomer and polymers for each macro-molecule group

Answer 1

Carbohydrates: monosaccharides and polysaccharides
Lipids: Fatty Acids and Triglycerides
Proteins: amino acids and polypeptides
Nucleic Acids: nucleic Acids and DNA/RNA

Question 2

Low Level- Functions of Each molecular group.
Carbohydrates

Answer 2

Primary source of energy for cells. Storage of simple sugars.
Make up the cell walls of plants.

Question 3

Low Level-Functions of Each molecular group.
Lipids:

Answer 3

Creates barrier necessary for the cell membranes to Function. Includes steroids which serve as a type of molecular messenger for the body. Long term energy storage.

Question 4

Low Level-Functions of Each molecular group.
Protiens:

Answer 4

Catalyze chemical reactions. Hold cells and tissues together. Give cells their shape. Allows cell to change shape and move. Messenger that switch’s cell process off and on. Recognize and attach foreign cells and viruses.

Question 5

Low Level-Functions of Each molecular group.
Nucleic Acids:

Answer 5

Carries genetic instruction by coding for proteins. Builds proteins and performs photosynthesis.

Question 6

Low Level- Similarities and differences in amino acid structure.

Answer 6

Similarities: Have the similar structure.
Differences: Some have the side chain group and others have the R-group.

Question 7

Lower Level- The four levels of protein structure

Answer 7

1. Primary
2. Secondary
3. Tertiary
4. Quaternary

Question 8

Lower level-What happens during protein denaturation

Answer 8

During denaturation the secondary and tertiary structures get destroyed and only the primary structures is retained.

Question 9

Medium Level-Why and how would the structure and function of a protein change if a hydrophobic amino acid was substituted for a hydrophilic one?

Answer 9

It changed the structure due to a single amino acid and substitution can affect the proteins function.
