Any substance to which an electron may be transferred.

Any molecular entity that serves as an electron acceptor and electron donor in an electron transport system.

Any metabolic process involving the breakdown of complex substances into smaller products, including the breakdown of carbon compounds with the liberation of energy for use by the cell or organism.

The breakdown into simpler components of a macromolecule, any large molecule including proteins, nucleic acids and carbohydrates.

The energy-requiring part of metabolism in which simpler substances are transformed into more complex ones, as in growth and other biosynthetic processes.

positive regulation of calcium-mediated signaling

Any process that activates or increases the rate of calcium-mediated signaling.

The formation from simpler components of macromolecules, large molecules including proteins, nucleic acids and carbohydrates.

The process whose specific outcome is the progression of the mammary gland over time, from its formation to the mature structure. The mammary gland is a large compound sebaceous gland that in female mammals is modified to secrete milk.

A series of molecular signals initiated by the cross-linking of an antigen receptor on a B- or T cell.

A series of molecular signals initiated by the cross-linking of an antigen receptor on a T cell.

A series of molecular signals initiated by the cross-linking of an antigen receptor on a B cell.

regulation of antigen receptor mediated signaling pathway

regulation of antigen receptor mediated signalling pathway

Any process that modulates the frequency, rate or extent of signaling pathways initiated by the cross-linking of an antigen receptor on a B- or T cell.

regulation of T cell receptor signaling pathway

regulation of T-lymphocyte receptor signalling pathway

Any process that modulates the frequency, rate or extent of signaling pathways initiated by the cross-linking of an antigen receptor on a T cell.

The process by which the anatomical structures of appendages are generated and organized. Morphogenesis pertains to the creation of form. An appendage is an organ or part that is attached to the trunk of an organism. For example a limb or a branch.
