Introduction Flashcards
1
Q
Biochemistry and Biomolecule Dfn
A
- study of chemistry ( chemical constituents, reactions and processes ) that occurs within living organism at the cellular level
- organic carbon compounds which constitutes and are made by living organisms
2
Q
Cell theory
A
-all living organisms are made of 1 or more cells and new one come from preexisting cells
3
Q
6 major and minor elements
A
- C, H, O, N, P, S
- Ca, K , Mg, Na, Fe, Zn
4
Q
4 major bio molecules, their monomers and bonds they make
A
- proteins / amino acids - peptide bonds
- lipids / fatty acids - ester bonds
- carbohydrates/ monosaccharides- glycosidic bonding
- nucleic acids / nucleotides- phosphodister bonding
5
Q
Protein function
A
- regulations ( hormones )
- speed up reactions ( enzymes )
- transport carrier molecules ( hemoglobin)
- structural components ( keratin )
- make up other biomolecules (glycoproteins)
- movement ( via muscle contractions)
- protection ( antibodies )
- growth and tissue repair
6
Q
Carbohydrates function
A
- source and storage of energy ( glycogen in people )
- make up other biomolecules
- molecular tags
- structural components ( cellulose cell wall )
7
Q
Lipids functions
A
- regulation ( steroid hormones )
- thermal insulation
- make up other bio molecules
- source and storage of energy
- structural components
- absorb lipophilic compounds
8
Q
Nucleic acids
A
- DNA stores genetic info and forms chemical basis for hereditary
- RNA vital in protein synthesis and gene expression
9
Q
Self-maintaining capacity of cells
A
-take in nutrients and converts them into energy for various-functions and and into structural components for tissue repair
10
Q
Other important bio molecules
A
Vitamins and minerals
11
Q
Oglio , Mono and Poly
A
: 2-10
: 1
: >10
12
Q
Monomers and polymerization
A
-monomers undergo polymerization ( which require energy ) ie covalent linkage or numerous sub units to form a long chain called polymer
