Beta-1 Alpha-4 glycosidic linkage
Chitin Correct Answer: polysaccharides-insects exoskeleton
hydrophobic lipids Correct Answer: in fur to protect animals from water
triglycerol Correct Answer: three fatty acids to a glycerol backbone in
dehydration reaction (release H2O)
stearic acid Correct Answer: common saturated fatty acid
saturated fatty acid Correct Answer: hydrocarbon chains connected to SINGLE
BONDS
unsaturated fatty acid Correct Answer: have one or more DOUBLE BONDS
lipids Correct Answer: waxy covering on leaves
phospholipids Correct Answer: molecule with TWO FATTY ACIDS and a phosphate
group
,HYDROPHILIC HEAD AND HYDROPHOBIC TAILS
Steroids Correct Answer: composed of 4 fused hydrocarbon rings
amino acids Correct Answer: central asymmetric carbon
20 common amino acids found in protein
peptide bonds Correct Answer: dehydration synthesis reaction-insulin
secondary structures Correct Answer: alpha and beta pleated sheets
hydrophobic reactions Correct Answer: in tertiary structure
4 levels of protein structures Correct Answer: -primary
-secondary-alpha and beta
-tertiary
-quaternary
nucleotide Correct Answer: form basic structural unit of DNA and RNA
made of 3 components: nitrogenous base, pentose sugar, cheormone phosphate
groups
what pentoses are in DNA and RNA Correct Answer: purines-double rings
purity-single rings
native DNA Correct Answer: antiparallel double helix
antiparallel Correct Answer: 5' to 3' and 3' to 5'
ribosome Correct Answer: two parts: large sub-unit and small sub-unit.
adds correct peptide chain
RNA Correct Answer: has uracil
DNA Correct Answer: human genome project
double strands give it the spiral structure
,elements Correct Answer: comprise matter including living things
matter Correct Answer: any substance that occupies space and has mass
cis and trans Correct Answer:
cis Correct Answer: when both hydrogens are on the same side
trans Correct Answer: both hydrogens are on different sides
phospholipid Correct Answer: must have two fatty acids attached and a modified
phosphate group connected to a backbone
alpha carbon Correct Answer:
glutamate Correct Answer: neurotransmitter in the brain
What are the 7 properties of life? Correct Answer: Order/Organization
Metabolism
Evolution
Regulate/Control
Growth/Development
Responce to environment
Reproduction
Organization of biology that we will use in this class in inc. complexity? Correct
Answer: Atom, molecule, organelle, & cell
Scientific Method Correct Answer: Make an observation
Ask a question
formulate a hypothesis
make a prediction
collect data
draw conclusion
Hypothesis def. Correct Answer: is a tentative explanation for an observation,
phenomenon, or scientific problem that can be tested by further investigation
, Theory def. Correct Answer: is a plausible or scientifically acceptable, well-
substantiated explanation of some aspect of the natural world... that applies in a
variety of circumstances to explain a specific set of phenomena and predict the
characteristics of as yet unobserved phenomena
Macronutrients or Essential Elements def. Correct Answer: comprise ~99.9%
Micronutrients or Trace Elements Correct Answer: are needed in minute
quantities
The 6 elements of life Correct Answer: Carbon, Oxygen, Hydrogen, Sulfer,
Phosphorus, & Nitrogen
Biological properties of water Correct Answer: Ability to moderate Temp.
Chemical rxn participant
Cohesive/adhesive
Expansion upon freezing
VERSATITLTY AS A SOLVENT & BASIS OF THE pH SCALE.
Hydrophilic Correct Answer: Water loving; polar molecules; & dissolve easily in
water.
Hydrophobic Correct Answer: Water hating; non polar molecules; Insoluble
pH def. Correct Answer: is a measure of the conc'n of H+ in solution; changes by
10^x, where x is the pH.
Acid def. Correct Answer: releases H+ ions.
pH goes down and the conc'n of H+ ions goes up
Bases def. Correct Answer: Consumes H+ ions.
pH goes up because the H+ ion goes up
Isomers Correct Answer: Two molecules with the same chemical formula but
different structural formula.
