The model used to show the cell's membrane
(a)
Which is not a molecule involved in the membrane
protiens
phospolipid
cholesterol
polysacharide
nucleic acid
any protein needed in order for the cell to function
(a)
protien that goes through both leaflets
(a)
a protein on only 1 leaflet that can move
(a)
_______ proteins are channels and pumps
transport
intergral
trans membrane
tube
help facilitated diffusion
(a)
help active transport, and use ATP to create a concentration gradient
(a)
(a) diffusion - movement with the concentration gradient
movement against concentration gradient
(a)
Enzymes are an example of a protein in the membrane
true
false, lipid
false, cholesterol
false, enzymes are not in the membrane
protein with sugar attached that aids in recognition and binding
(a)
Trans-membranec channels also help
create a concentration gradient when closed
move large polar molecules
create a sling shot for ions when channels first open
use atp to transport material
A target fro signals such as neurotransmitters
(a)
an example of what receptor cells do is
mediated endocytosis in the immune system
receiving the signals we give them
producing proteins
a place for exosytosis
examples of peripheral proteins are all the following except
enzymes
receptors
identifying and adhesion molecules
glycoproteins
transport pump
Movement of H2O across the membrane with the gradient through a protein called an aquaporin
(a)
Make a stable internal enviroment by forming a barrier that blocks water
(a)
a molecule that has hydrophilic and hydrophobic parts
(a)
an amphepathic molecule that both stabilizes the membrane and keeps it fluid
(a)
(a) diffusion - Movement of small nonpolar molecules (CO2 and O2) across the membrane with the gradient
important for cell to cell communication
(a)
Any spread of molecules from higher to lower concentration
(a)
engulfing a particle in a membrane vesicle
(a)
engulfing fluid in a membrane vesicle
(a)
protiens and glycoprotiens that help specialized cells connect to eachother
(a)
CAMs are important because
they help bind cells
allow cells in tissue to communicate effectively with one another
sort cells into appropriate places
specialize the cells for the specific tissue they will be apart of
(a) - connect to cytoskeleton inside the cell and help relay information to the outside of cell
glycoproteins do all of the following except
act as a membrane marker
communicate information to the outside of the cell
can bind tissue in place
specialize cells
an example of a glycoprotein Mrs. Shaffer mentioned in class
integrins
outergrins
polypeptides
nucleic acid
tissue that covers the surfaces of organs and our skin are made up of (a) cells
The ways epithelial cells bond
hemidesmosome
adherens and desmosomes
tight junctions
gap junctions
surface junction
Anchors the cell to the ECM or the bottom
(a)
create layers in epithelial tissue by binding cells together and relaying info.
(a)
Desmosomes join
(a)
adherens join
(a)
do not help cells communicate, but firmly hold cells together on their apical sides (water proof)
(a)
the open inner surface of body cavities and organs. Lines the lumen
(a)
create bridges between cytoplasm that share molecules and impulses for quick communication
(a)
the process of division that develops multi cellular organisms
(a)
DNA is replicated
(a)
chromatin condenses
(a)
chromosomes align in the center of the cell
(a)
chromatids seperate and pulled toward opposite ends of the cell
(a)
2 separate nuclei are formed
(a)
Differentiation happens when....
a cell divides
cells are told which genes to activate and which to not
cells are put next to the cells they supposed to become
a cell dies and the new one becomes the next stage
The main types of tissue are
ectoderm
endoderm
mesoderm
polyderm
skin, and some nervous tissue (outer)
(a)
muscular, skeletal, cardiac, kidney tubule cells (make urine) tissue (muscular)
(a)
lungs, stomach, liver, pancreas, intestines, and esophagus (inner)
(a)
cells take apart and recycle or spits out parts it doesn't need
(a)
responsible for the degradation/separation of the majority of intracellular proteins
(a)
cell suicide
(a)
where do desmosomes link
intercellular space
inside the older cell
inside the newer cell
inside one of the cells (doesn't matter which one)
