Cell junction

In which cell-surface junction fused membrane reveals five-layered structure?

Which type of cell surface junctions abundantly occur in epithelial tissues?

Intercellular junction in animal cell is

[A] : Acetylchoiine allows a nerve cell to com- municate chemically with a muscle cell at neuromuscular junction. [R]: Acetyicholine diffuses across the junc- tion and binds to some receptors on mem- brane of muscle cell.

The cellular junctions that join the epithelium cells to the basal lamina are

Plasmodesmata are junctions between plant cells. These involve modification of

The contact potential at the junction site in a P-N junction is-

The emitter-base junction of a transistor is .........biased while the collector-base junction is.......biased

At the neuromuscular junction :

Give the direction of thermoelectric current (i) at the cold junction of copper-bismuth, (ii) at the hot junction of iron-copper and (iii) at the cold junction of platinum lead.
