25
Chemical reaction
A process in which covalent or ionic bond is formed or broken
26
Chemical equation
Symbolizes course of chemical reaction
27
Classes of chemical reactions
Decomposition reactions and synthesis reaction
28
Decomposition reaction
Large molecule breaks down into two or more smaller ones
29
Synthesis reaction
Two or more small molecules combined to for a larger one
30
Reach equilibrium
When ratio of products to reactants is stable
31
Reactions rates increase when
The reactants are more concentrated, the temperature rises or a catalyst is present
32
Metabolism
All chemical reactions of the body
33
Catabolism
Energy increasing decomposition reactions
34
Word for energy releasing
Exergonic
35
Anabolism
Energy storing synthesis reactions
36
Endergonic means
Energy storing
37
Oxidation
An exergonic reaction in which electrons are removed from a reactant
38
Reduction
A reaction in which electrons are donated to a reactant
39
Organic chemistry
The study of compounds containing carbon
40
Four categories of carbon compounds
Carbohydrates lipids proteins nucleic acids
41
Macromolecules
Very large organic molecules with high molecular weights
42
Polymers
Macromolecules made of a chain of monomers
43
Monomers are linked together by
Dehydration synthesis
44
Dehydration synthesis
Monomers covalently bonded together to form a polymer with the removal of a water molecule
45
Hydrolysis
Splitting a polymer with water
46
Carbohydrates primary function is
Energy
47
Carbohydrates general formula is
(Ch2o)n
48
The 3 sizes of carbohydrates
Monosaccharides, disaccharide and polysaccharides
49
Monosaccharides
Simple sugar types like blood sugar
50
3 types of monosaccharides
Glucose fructose galactose
51
Disaccharides
Table sugar
52
3 types of disaccharides
Sucrose lactose maltose
53
Polysaccharides
Glycogen stored in skeletal system and liver
54
Starch
Energy storage in plants that is digestible by humans
55
Cellulose
Structural molecule in plants important for human digestion fiber but not actually digestible
56
Are carbohydrates hydrophobic or hydrophilic
Hydrophilic
57
Lipids
Grouped together because part or the whole molecule is hydrophobic
58
4 lipids are
Fatty acids triglycerides phospholipids steroids
59
Fatty acids
chain of 4-24 carbon atoms with carboxyl group on one end and methyl group on the other end
60
Triglycerides
Three fatty acids linked to glycerol formed by dehydration synthesis
61
Since triglycerides are hydrophobic how are they transported in the human body
Lipoproteins
62
Phospholipids
Similar to. Wirral fats but replace one fatty acid with a phosphate group
63
Composition of phospholipid molecule is
A polar head that forms hydrogen bonds and 2 nonpolar fatty acid tails that only interact with lipids
64
Composition of cell membrane
A double layer of phospholipids
65
Cholesterol
Parent steroid with which the other steroids are synthesized
66
Protein
A polymer of amino acids
67
Amino acids
Central carbon with 3 attachments
68
3 attachments of amino acid are
Amino group carboxyl group and radical group
69
Peptide
Any molecule composed of 2 or more amino acids
70
Protein structure
Primary secondary tertiary
71
