Macropinocytosis is an endocytic mechanism involved in fluid uptake. Viruses that belong to adeno, vaccinia, picorna and other viruses families... View Article
Viruses can enter cells that are covered by phospholipid bilayer, serving as the cell's natural barrier to their immediate environment. The type... View Article
There are two types of exocytosis - Constitutive exocytosis - without the need for any particular type of signal, secretory material is... View Article
In exocytosis, cells direct contents of secretory vesicles out of the cell membrane. Such vesicles have soluble proteins to be released to the... View Article
It is the process of transfer of internalized receptors across cells to the opposite domains of the plasma membrane. It mostly takes place in... View Article
The different phases of clathrin-mediated endocytosis are - Macromolecules associate with particular cell surface receptors Receptors are... View Article
In amoeba, the different phases of phagocytosis for food capturing are: On phagocytic cell, attachment of the macromolecules to the receptor... View Article
The membrane which forms an envelope in the mycobacteria is characterized by its low permeability. It imparts resistance of microbes to... View Article
Cell walls of gram-positive bacteria lack an outer membrane. However, it has a thick murein layer. Teichoic acids in these bacteria are... View Article
These are the steps occurring during the transportation of Na+ and glucose - Na+ and glucose binds to the conformation with outward-facing... View Article
Vacuoles are involved in - Serve as storage organelles, containing small molecules and water. Store minerals, salts, proteins, pigments,... View Article
Symport is a form of active transport. It uses the downhill movement of solute species from high concentration to lower for the movement of other... View Article
Antiport is a form of active transport. Two species of solutes or ions are pumped in opposite directions across a membrane in antiport. One of... View Article
In this process, solutes and water molecules move across the cell membrane because of hydrostatic pressure produced by the system. Based on the... View Article
Several bacteria have a role to play in the sulfur cycle. These sulfur compounds form a key part of proteins. During decomposition, the... View Article
The iron cycle revolves around the ferrous iron to ferric iron and then back again. In some bacteria, ferric iron reduction forms a part of the... View Article
