Macfarlane burnet theory about antigen antibody reaction?
The Burnet theory about antigen antibody reaction is a basic concept about how we make antibodies specific to a foreign substance which has the ability to induce an immune response (antigen). Each B cell displas one unique type of B cell receptor on their surface (which is basically a membrane bound antibody). Therefore many B cells, each expressing its own type of B cell receptor are needed to cover the inexhaustable number of antigens that are possible, in the hope that one type of B cell receptor will be able to recognise the shape of that antigen. If one B cell does recognise the antigen in question, then this B cell will become activated to make many clones of itself, which will obviously carry identical B cell recptors which fit the antigen. |Therefore the clonal selection theory by Burnet is about antibody antigen interactions which result in the 'best-fit' B cell receptor inducing a reaction to tell the B cell carrying the receptor to multiply and produce lots of identical antibodies which can then be secreted to bind to the antigen they are specific for.
What is the function of a receptor?
Receptor proteins are used to pass messages between cells. They send the messages from outside of the cell to the inside of the cell.
What is e difference between receptor proteins and marker proteins?
receptor protein and marker protein are differente''marker protein have cell surface marker that act as name together, the identification of different types of cells and the receptor proteins transfer information from the outside of the cell to the inside receptor proteins are like boulders that how it's difference.
A ligand produces a response in a cell if it finds the right kind of?
receptor. When a ligand binds to its receptor on the cell surface or within the cell, it triggers a specific biological response or signaling pathway. The specificity of this interaction between ligand and receptor is critical in determining the cellular response.
What is the difference between a ligand and a receptor protein?
A ligand is a molecule that binds to a receptor protein, while a receptor protein is a protein that recognizes and binds to specific ligands, triggering a biological response. Simply put, a ligand is like a key that fits into a receptor protein like a lock, initiating a signaling cascade in the cell.
What is the name of the nerve cell between the receptor cell and the central nervous system?
SENSORY NEURONE
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.
What are the differences between Bcell receptors and Tcell receptors?
there are different types of b cell and t cell. both are lymphocytes, a subclass of white blood cell. the t cells are mainly used in identifying antigens and releasing chemicals which attact macrophages (big immune cells which 'eat' antigens), to destroy the antigen. b cells are used in the production of antibodies. when they encounter a new antigen, plasma cells and memory cells are formed from the division of a b cell. the memory cell remembers the antigen and which antibody to use, while the plasma cell makes the antibodies to fight a particular antigen or class of antigens
What is the meaning of receptor repertoire?
Our DNA encodes many different types of receptors. Since just about every cell of the body contains the exact same DNA, you would think that all would have the same set of receptors too. But while every cell does have the DNA necessary to make any receptor, each cell only makes the receptors that are specific to its particular cell type. The receptors made by a specific cell type are collectively called that cell's receptor repertoire.
What is the difference between endocytosis and phagocytosis?
Phagocytosis is a kind of endocytosis. Endocytosis includes phagocytosis, pinocytosis and receptor-mediated endocytosis. These are just different ways to enter large molecules inside the cell.
Define receptor of body?
A receptor is located on a cell membrane. Any neuronic transmission, hormone, etc. that cannot get inside of the cell's membrane will sit on the receptor in order to pass its message along to the cell. When the molecule sits on the receptor, it causes a series of reactions to occur inside of the cell. From the series of reactions that occur inside of the cell, the message is passed along, and the cell will perform as indicated by the molecule on the cell receptor.
What cell part receives nerve impulses and hormones from other?
receptor molecules on cell membranes receptor molecules on cell membranes
