What is Ephagy in biology?

Ephagy is also known as cell vomiting or emeiocytosis. It is the reverse of endocytosis. Ephagy occurs when there’s cell secretion, removal of undigested food from food vacuoles, etc. Through vesicles, waste materials are expelled.

What is cell vomiting?

Exocytosis: It is a process of exudating the secretory products or undigested waste products to outside of the cell cytoplasm through plasma membrane. This process is called cell vomiting or ephagy.

What does exocytosis do in a cell?

Exocytosis is the process by which cells excrete waste and other large molecules from the cytoplasm to the cell exterior [49] and therefore is the opposite of endocytosis. Exocytosis generates vesicles referred to as secretory or transport vesicles (Chapter 17).

What is cell drinking called?

One specific form of endocytosis is called pinocytosis which is also known as “cell drinking”. Larger particles such as microbes, bacteria and cellular debris are internalised in a process called phagocytosis, which you can consider as “cell eating”.

What is Heterophagy in lysosomes?

Definition: Heterophagy is the process of lysosomal digestion of materials ingested from the extracellular environment. Extracellular materials are endocytosed into vacuoles (endosomes or phagosomes), which eventually fuse with lysosomes to form phagolysosomes, where the engulfed material is digested.

What is Emeiocytosis?

(ĕk′sō-sī-tō′sĭs) pl. ex·o·cy·to·ses (-sēz′) A process of cellular secretion or excretion in which substances contained in vesicles are discharged from the cell by fusion of the vesicular membrane with the outer cell membrane.

What is vomiting biology?

Vomiting is the forceful expulsion of contents of the stomach and often, the proximal small intestine. It is a manifestation of a large number of conditions, many of which are not primary disorders of the gastrointestinal tract.

What is cell vomiting Class 9?

Exocytosis: In this process the membrane of a vesicle can fuse with plasma membrane and extrude its contents to the surrounding medium. This process is also named as cell vomiting.

What is exocytosis and endocytosis in biology?

Endocytosis is the process of capturing a substance or particle from outside the cell by engulfing it with the cell membrane, and bringing it into the cell. Exocytosis describes the process of vesicles fusing with the plasma membrane and releasing their contents to the outside of the cell.

What is cell eating called?

Solid particles are engulfed by phagocytosis (“cell eating”), a process that begins when solids make contact with the outer cell surface, triggering the movement of the membrane. Phagocytosis occurs in the scavenging white blood cells of our body.

What are most cell membranes principally composed of?

Cell membranes are composed primarily of fatty-acid-based lipids and proteins. Membrane lipids are principally of two types, phospholipids and sterols (generally cholesterol).
