AP Exam Review Flashcards
Dehydration synthesis
forming, synthesis, anabolic, endergonic
Hydrolysis
breaking, digestion, catabolic, exergonic
Carbohydrate bond
glycosidic linkages
Lipid bond
ester bonds
Unsaturated fats
double bond, liquid at room temp
Saturated fats
single carbon bonds, solid at room temp
Nucleic acid bond
phosphodiester bonds in backbone, hydrogen bonds in bases
Protein bond
peptide bond and disulfide bridges
Amino acid parts
carboxyl (COOH), amino group (NH2), central carbon, variable R group
Nucleic acid monomer parts
sugar, phosphate, and base
Primary protein structure
amino acid chain
Secondary protein structure
alpha helix (hydrogen bonds)
Tertiary protein structure
globular mass
Quaternary structure
more than one polypeptide folding
Simple diffusion
passive, from high to low concentration, small and uncharged ex. O2, CO2
Facilitated diffusion
passive, from high to low, large and polar molecules
Active transport
transports molecules from low to high, uses ATP
Water potential
water moves from high to low water potential
Hypertonic
high solute
Hypotonic
low solute
Isotonic
equal solute and water
Competitive inhibition
competing for active site
Non-competitive inhibition
attaches at allosteric site and changes active site
Coenzymes
organic molecules helping enzymes
Cofactors
inorganic molecules helping enzymes
Light independent reactions
the calvin cycle
Oxidative phosphorylation
electron transport chain
Substrate-level phosphorylation
glycolysis and the krebs/citric acid cycle
Cytokinesis in animal cells
cleavage of membranes
Cytokinesis in plant cells
cell plate reforms new cell wall
Cell-mediated responses
cytotoxic T cells target pathogens in cells
Humoral responses
B cells produce antibodies against specific antigens
Nuclear division
when no cytokinesis occurs and the cell has extra genetic material now
Polarized neuron
Na(+) outside, K(+) and Cl(-) inside
Mendel’s laws
Law of dominance, segregation, and independent assortment
Homologous pairs
chromosomes of same structural features
Sister chromatids
identical half of a chromosome
Incomplete dominance
traits are blended
Codominance
recessive trait is not fully masked ex. spotting
Epistasis
one gene effects the expression of another
Polygenic
many genes affect one trait
Nondisjunction
the failure of chromosomes to separate at anaphase of meiosis
DNA building
DNA is made in the 5’ to 3’ direction
Central dogma
DNA-RNA-protein-trait
Lytic cycle
viruses reproduce in a cell then rupture and move to new cells
Retrovirus
use reverse transcriptase to create RNA-DNA-protein-trait
Mutualism
+/+
Commensalism
+/0
