Chapter 1-5 Flashcards
Dehydration Synthesis
water is taken out of a monomer,to form a larger molecule
Hydrophobic
avoids water
Hydrophilic
attracted to water
Polar
molecules can form bonds with each other
Nonpolar
molecules can’t form bonds with each other
Saturated Fats
lipids that have maximum hydrogen atoms and no double bonds
Unsaturated Fats
lipids that have one or more double bonds
Phospholipids
lipids with polar and nonpolar sides
Amino Acids in Proteins
causes sickle cell disease
Enzymes
proteins that speed up chemical reactions
Primary Structure
sequence of amino acids in a polypeptide
Secondary Structure
shaping of polypeptide
Tertiary Structure
three dimensional shape of polypeptide
Quaternary Structure
overall protein structure of two or more polypeptide units
DNA
nucleic acid that stores information (T,C,G,A)
RNA
nucleic acid that transports information (U,C,G,A)
Characteristics of Living Things
order, regulation, evolutionary adaptation, energy processing, response to environment, reproduction, and growth and development
Main Source of Energy for All Life
sunlight
Levels of Organization
biosphere -> ecosystems -> communities -> populations -> organisms -> organ systems -> organs -> tissues -> cells -> organelles -> atoms -> molecules
Positive Feedback
enzymes stimulate a step to regulate process
Negative Feedback
enzymes block a step to regulate process
Ionic Bonds
attraction between anions and cations
Covalent Bonds
bond forms when atoms share electrons
Surface Tension
how hard it is to break the surface of a liquid
