1
Q
non polar bonds
A
- strong
- equal sharing of electrons
- hard to break apart
2
Q
polar covalent bonds
A
- strong
- unequal sharing of electrons
- charged molecule
3
Q
ionic bond
A
two atoms with different electronegatives come together
- not equal sharing, unstable
- can be positive or negative
- one atom gets all the elctrons all the time
4
Q
hydrogen bond
A
- weak
- loose temporary bond
- two atoms become loosly attracted to eachother but don’t share electrons
- if there are a lot of them such as in DNA it is collectively strong
5
Q
synthesis reactions
A
- take energy
- also known as anabolism
6
Q
electronegativity
A
greater pull around the nucleus
7
Q
decompostition reaction
A
- opposite of synthesis
- catabolic
8
Q
water
A
- solvent
- great cohesiveness and surface tension
9
Q
acids
A
- high in H+
- numbers under 7 on ph scale
10
Q
bases
A
- high in OH-
- numbers higher than 7 on ph scale
11
Q
4 macromolecues
A
lipids, carbs, nucleic acid, and proteins
12
Q
lipids
A
insoluable in water
-llong carbon or hydrocarbon chains
13
Q
phospholipids
A
has a charge
- charged heads go towards water
- lipid tail doesn’t like water
14
Q
steroids
A
- are lipids (are insoluable in water)
- float through blood and attach to cells to send signals
- help you adapt from outside environment (ex. temp)
15
Q
carbs
A
category two
- an energy source
- CH2O are sugars
16
Q
4 types of carbs
A
monosaccharides (simple) disaccharides oligosaccharides polysaccharides (complex)
17
Q
proteins
A
enzymes are made up of proteins
-proteins act as catalysts in your body
18
Q
amino acids
A
- building blocks of proteins
- 21 of them
- peptide bond is formed between amino acids
