Cell Bio Quiz #1
cell structure in eukaryotes that encodes heritable information for building proteins (genes)
DNA
which structures are "membrane bound organelles?" -- ribosomes, RER, DNA, plasma membrane, cytosol, mitochondria
RER and mitochondria
cell structure in eukaryotes where protein synthesis and/or trafficking occurs (generally membrane or secreted proteins)
RER and ribosomes
which microscopy looks at the surface of a lymphocyte?
SEM
which microscopy obtains a black and white image showing small organelles in a thin section of tissue?
TEM
what are the 3 major ideas of the cell theory?
all living organisms are composed of cells, cells are the fundamental unit of life, cells arise only by division of a previously existing cell
what are the 4 parts to an amino acid molecule and what type of macromolecule does it make?
carboxyl group, amino group, side chain, and alpha carbon. polypeptides
what is the role of the nucleotide in the cell?
carries genetic info for building proteins
in cells water is very important. ________ reactions are used to build polymeric (macro) molecules and _________ reactions are used to break them down.
condensation, hydrolysis
cell structure in eukaryotes that houses enzymes and organelles in an aqueous solution
cytosol
which microscopy highlights specific cell structures using fluorochrome labeled tags?
fluorescence
what are the 2 parts to a fatty acid molecule and what large molecule does it make?
hydrocarbon tail and carboxyl group (head). phospholipids (animal fat)
what role does the fatty acid play in the cell?
insulation, energy source, and membrane
which microscopy looks at live cells in tissue culture?
light
cell structure in eukaryotes that generates energy (ATP)
mitochondria
which of the following provides evidence for the endosymbiont theory?
mitochondria and chloroplasts have ribosomes, a single circular chromosome, and make proteins
what are polar molecules?
molecules that share electron pairs unequally
what is the role of the amino acid in the cell?
movement, transport, structure, receptors, and enzymes
what are the 3 parts to a nucleotide (ATP) molecule and what type of macromolecule does it make?
nitrogen base, sugar/ribose, phosphate groups. DNA
cell structure in eukaryotes that controls cellular activities, houses the genetic material, and divides when cell divides
nucleus
cell structure in eukaryotes that control movement of molecules in and out of cell
plasma membrane
what type of macromolecule does a 6-Carbon Simple Sugar make and what is its one role in the cell?
polysaccharides (starch, glycogen, cellulose). source of energy/fuel, storage, and structure
which structures can be found in prokaryotic cells? -- ribosomes, RER, DNA, plasma membrane, cytosol, mitochondria
ribosomes, cytosol, plasma membrane, DNA
what is the hydrolysis reaction?
water is added to break it down (addition of water)
what is the condensation reaction?
water is expelled from the reaction (removal of water)
