Questions 10

Answers

1
The binding of a signal molecule and a receptor protein is...
is never a protein
only occurs in prokaryotic cells
very random
highly specific
2
What do cells typically use to communicate with other cells over long distances?
none of the above
difference in charges across a membrane
osmosis
hormones
3
The term "local regulator" refers to...
signal transduction pathway
long distance signaling
a messenger molecule that travels only a short distance
ligands
4
What is the role of a ligand in cell signalling?
its the response that occurs
binds to a receptor
diffuses through the cell membrane
makes cookies.
5
Process by which a signal on a cell is converted into a specific cellular response
ion gated channel
evolution of cell signaling
G-protein coupled receptor
signal transduction pathway
6
Why can some chemical messengers cross the membrane and activate receptors in the cytoplasm?
they are small and hydrophobic
they are hydrophillic
they are large and hydrophobic
they are small proteins
7
What does it mean if something is hydrophillic?
its water loving
it is attracted to water
it is polar
all of the above
8
The following illustration demonstrates...
how different cells communicate
g-protein coupled receptors
ligands
ligand gated channels
9
what does it mean if something is hydrophobic?
its repels water
its non-polar
an example would be oil
all of the above
10
A cell's ability to detect a signal molecule depends upon...
whether or not is long distance or short distance
whether or not it involves GTP or ATP
whether or not it has a receptor specific to that signal
all of the above
