Question

I need help with these questions. What is the right answer and why?

1. Neurotransmitter receptors:

a. are restricted to synaptic bud membranes

b. are present on the cell membrane opposing synaptic bud

c. do not have any transmembrane domains

d. function as adhesion molecule

2. Plasma membranes:

a. are highly symmetric with respect to glycosylation

b. leaflets have very different lipid composition

c. leaflets have identical protein composition

d. semi-fluid, fully permeable and pliable

3. Multi-drug resistance pumps:

a. transport substances up their concentration gradient

b. are found only in bacteria

c. are inner mitochondrial membrane proteins

d. are secreted proteins

1. Neurotransmitter receptors:

b. are present on the cell membrane opposing synaptic bud- also called as the post synaptic membrane present on the dendrite of another neuron.

2. Plasma membranes:

a. are highly symmetric with respect to glycosylation- Proteins present on both sides of the membrane are glycosylated.

3. Multi-drug resistance pumps:

a. transport substances up their concentration gradient-Its an ATP dependant pump present on the membrane with broad substrate specificity.
