Exocytosis is a type of cellular transport that allows materials to move across the plasma membrane of a cell. Which of the stat
Ilya [14]

Answer:

C. Exocytosis uses transport vesicles to export materials from the cell

Explanation:

Exocytosis is the reverse process of endocytosis including the expulsion of the material that is membrane -encapsulated (material is packaged in the vesicles ) inside the cell out of the cell. It has following steps :

1) The cell forms a vesicle around a material which is to be expelled.

2) The vesicle is transported to the cell membrane.

3) The vesicle membrane fuses with the cell membrane and releases the contents from the cell.

Hence option C. Exocytosis uses transport vesicles to export materials from the cell IS THE RIGHT OPTION.

g protein-activated inwardly rectifying potassium channels mediate depotentiation of long-term potentiation
Svetlanka [38]

Long-term potentiation (LTP) is considered a cellular correlate of learning and memory. The presence of G protein-activated inwardly rectifying K(+) (GIRK) channels near excitatory synapses on dendritic spines suggests their possible involvement in synaptic plasticity. However, whether activity-dependent regulation of  channels affects excitatory synaptic plasticity is unknown. In a companion article we have reported activity-dependent regulation of GIRK channel density in cultured hippocampal neurons that requires activity oF receptors (NMDAR) and protein phosphatase-1 (PP1) and takes place within 15 min. In this study, we performed whole-cell recordings of cultured hippocampal neurons and found that NMDAR activation increases basal GIRK current and GIRK channel activation mediated by adenosine A(1) receptors, but not GABA(B) receptors. Given the similar involvement of NMDARs, adenosine  receptors, and PP1 in depotentiation of LTP caused by low-frequency stimulation that immediately follows LTP-inducing high-frequency stimulation, we wondered whether NMDAR-induced increase in GIRK channel surface density and current may contribute to the molecular mechanisms underlying this specific depotentiation. Remarkably, GIRK2 null mutation or GIRK channel blockade abolishes depotentiation of LTP, demonstrating that GIRK channels are critical for depotentiation, one form of excitatory synaptic plasticity.
