Do hormones enter cells through exocytosis or pinocytosis?

Hormones typically enter cells through specific receptor-mediated endocytosis, a form of pinocytosis. The hormone binds to a receptor on the cell surface, initiating a process in which the hormone-receptor complex is internalized into the cell through vesicle formation. Hormones are not typically released by cells through exocytosis; instead, they are released into the extracellular space to exert their effects on target cells.


What includes phagocytosis pinocytosis and a receptor mediated form?

Endocytosis includes phagocytosis, pinocytosis, and receptor-mediated endocytosis. Phagocytosis is the process by which cells engulf large particles or pathogens, pinocytosis is the engulfing of fluids or small particles, and receptor-mediated endocytosis involves the uptake of specific molecules bound to receptors on the cell surface.


The difference between pinocytosis and receptor-mediated endocytosis is that?

pinocytosis is a non-specific process where the cell engulfs extracellular fluid and particles, while receptor-mediated endocytosis is a selective process that relies on specific receptors binding to ligands for internalization. Receptor-mediated endocytosis is more efficient and targeted compared to pinocytosis.


Which processes involves specific membrane receptors?

receptor-mediated endocytosis


Where do receptor molecules end up after receptor-mediated endocytosis?

Its NOT 'on the inside surface of the cell membrane' Probably ' on the inside surface of the vesicle'


Can cipro affect tinnitus?

Yes. This is mediated by ciprofloxacin's antagonism of the GABA(a) receptor, leading to NMDA receptor over-excitation and tinnitus.

How does receptor mediated endocytosis differ from receptor mediated facilitated diffusion?

endocytosis is when large substances are taken into the cell(does not require protien carriers or protien channels) .whereas f.diffusion is movement of "hydrophilic" molecules or "ions" in and out of cell through a protein carrier present in the cell membrane.


What is the importance of Receptor-mediated Endocytosis in the genetic disorder Familial Hyper-Cholesterolemia?

In mammalian cells, the LDL (low density lipoprotein) receptor transports cholesterol into the cell via receptor-mediated endocytosis. The cholesterol is then used by the cell for various metabolic functions and the receptor is recycled to the plasma membrane.In patients suffering from Familial Hypercholesterolemia, the genes encoding the LDL receptor are mutated, as a result of which cholesterol is unable to bind to the LDL receptor. This leads to accumulation of cholesterol in the circulation, hence causing disease. Patients suffering from this disease are treated using drugs called Statins, which inhibit an important enzyme involved in cholesterol biosynthesis.


What Is receptor mediated transport?

Endocytosis is the bulk transfer of materials from inside to outside of a cell with the help of special vesicles. Types of Endocytosis : 1) phagocytosis 2) potocytosis 3) receptor mediated endocytosis


Is Receptor-Mediated Endocytosis Passive or Active Transport?

It is niether. Its is passive actually. http://www.mansfield.ohio-state.edu/~sabedon/campbl08.htm #38. under Endocytosis, which is active passport, includes the example of Receptor-Mediated Endocytosis.
