Total questions: 17
Worksheet time: 16mins
membrane proteins are
lyases
cellulases
permeases
all of these
Cell membrane is
Semipermeable
permeable
selective permeable
impermeable
The membrane which allows passage of certain substances more readily than others is termed as.
permeable
impermeable
semipermeable
selective permeable
Diffusion of water through a selective permeable membrane is called
osmosis
diffusion
active transport
facilitated diffusion
Process of osmosis involves the movement of :
solute through a semi permeable membrane.
solvent through a semi permeable membrane
solution through a semi permeable membrane
non of these.
The term 'phagocytosis' has been coined by
Lewis
Huxley
Metchnikoff
Strasburger
phagocytosis may be characterized by which of the following statement.
it is a constitutive process
it involves fluid uptake by small vesicles
it is important in digestive processes in mammals.
it involves the uptake of cellular debris in large endocytic vesicles.
The blood cell which shows phagocytosis is
monocytes
platelet
eosinophil
basophil
The process by which large molecules moves out of the cell is called.
Reverse phagocytosis
phagocytosis
deplasmolysis
plasmolysis
Which of the following involves the non selective uptake of tiny droplets of extracellular fluid?
Exocytosis
pinocytosis
sodium pump
phagocytosis
Pinocytosis is:
Ingestion of solid particle
Ingestion of liquid particle
Changed permeability of plasmalemma towards ions
both a and b
A white blood cell is capable of producing and releasing thousands of antibodies molecules every second.Antibodies are large,complex protein molecules. How would you expect them to leave the cell?
by pinocytosis
by exocytosis
by active transport
by receptor -mediated endocytosis
Size of molecules that can pass through plasma membrane is :
1-15°A
8-10°A
15-75°A
10-13°A
The water soluble materials pass through the proteins called:
Spectrin
glycocalyx
glycoprotein
channel protein
extrinsic protein
The bio membranes allow active transport of substances because:
ATP synthesis is involved
Energy is needed for transport
A carrier is needed for transport
The substances are rapidly taken up
Active transport in a cell occurs in:
Ribosome
Microtubules
nuclear membrane
plasma membrane
Active transport in a cell occurs in:
Ribosome
Microtubules
nuclear membrane
plasma membrane
