ASU Bio 181 Exam 1
✅✅
1n order to examine cells which are smaller than can be detected by the human
senses what needs to be used ? - -technology
✅✅
A cell that is itself an organism must have a minimum of four needs presented in
lecture - -find food, find shelter, find mate, and reproduce.
A normal cell is _____ and ____ for growth. - ✅✅-mortal, anchorage
dependent
a singled celled eukaryotic organism - ✅✅ -has a limited number of
biomolecular machines
must find food, shelter, a mate and reproduce
escape from predators
✅✅
After a cell is pancake shaped in a cell culture dish, the order of events that
occurs as a cell walks is? - -filapodia, lamellipodia, cell muscle, retraction
fiber
✅✅
amino acids can be largely subdivided into groups. what are the two groups -
-hydrophobic and hydrophlic
an important checkpoint regular is at Gap2/M-phase transition. here cyclin B and
✅✅
Cdk1 activate and form MPF which becomes a ____ _____ ( two words) and
causes the DNA to condense into _______. - -histone kinase
chromosomes
✅✅
compared to bacteria which of the cell types below are not responsible for finding
food? - -lymphocyte, macrophage, and fibroblast
✅✅
comparing a singled cell eukaryotic organism with a multicellular organism such
as yourself identify the major difference from the list below. - -division of
labor
✅✅
consider the geography of cells. Actin filaments are present in the cell's ____ and
the microtubules are present in the cell's - -cortex
, cytokinesis in plant and animal cells takes two forms - ✅✅-animal: contarctile
ring formation
plant: phragmoplast formation
✅✅
explain what limits an individual cell from becoming more complex -
-individual cell have a limit number of biomolecular machines. In a
multicellular organism you get a division of labor between different cell types so
that the whole can do more than the sum of the parts with similar number of
biomolecular machines per cell.
✅✅
facilitated diffusion uses a channel to let components move down their
concentration gradient. - -true
for a cell to respond to a ligand relased from a cell and uses the circulatory
✅✅
system to get to the responding cell it is called ______ communication -
-endocrine
for a cell to respond to a ligands release from a neighboring cell where the ligand
✅✅
diffuses directly from one cell to another is called ______ communication -
-paracrine
✅✅
for protein to enter the endoplasmic reticulum as part of the endoplasmic
reticulum's lumen or part of the endoplasmic reticulum membrane: - -a
ribosome binds to the mRNA and a short stretch of protein is synthesized that
contains a signal sequence.
✅✅
if something is soluble in water a of hydration forms around it and it is termed. -
-hydrophilic
✅✅-technology
in the cell biology what can limit the progress of science -
is cholesterol good or bad to have in biological membranes - ✅✅-good
✅✅
list the three categories of cells in the body with regard to the cell cycle: -
-1) cells that never go through the cell cycle again once you're born
(neurons, muscles)
