1
Q
Organic Compounds: _ _ _ _
- CHON Makes up:__%
- What makes up 4%?
Trace elements:____
A
CHON
- 96%
- 4%Ca,P,K,S,Na,Cl, Mg (metals and common elements ig)
- 0.1% of Iodine and Iron (I,Fe)
2
Q
Isotopes
Radioisotopes
Radioactive decay
Radioactive Tracers
A
- Same # of protons, but diff # of neutrons
Radioisotopes: Unstable isotopes that gives off radiation
Radioactive decay: Measurable rate. Can determine age of fossils and rocks
Radioactive Tracers: radioisotopes that can trace paths of atoms throughout body
3
Q
Polar
A
- unequal sharing of electrons due to high electronegativity difference
- Partial charges
Ex. O2 and N2 have high e diff
- usually water soluble
4
Q
Non-polar
A
Ex. C and H
equal distribution of charges
not water soluable (oils and fats)
5
Q
Intermolecular Forces ( between other molecules)
A
- Strongest type of attraction force
- with NOF
- Crucial for cellular processes
- Individual H bonds are weak, esp when temp. increases, but are strong with a large quantity
- Allows for stability of 3D structures of large molecules (ex. proteins)
ex. H2O
6
Q
Other Van Der waals
A
- weak attractions
- momentarily attractions
- Large molecules have larger forces of attractions than smaller molecules
- Stabilize shape of large molecules (ex. Fats)
7
Q
Dehydration Reactions
A
- Joining two molecules by removing water
- One molecule loses H, the other loses OH
(condensation/synthesis rxns)
8
Q
Hydrolysis Reactions
A
- Separating molecules via addition of H2O
(decomposition Rxn)
9
Q
Neutralization Rxn
A
Acid and base –> make salt and water
10
Q
Redox Rxn
A
- Transfer of energy within cells
- LEO
- GER
