Vesicle (biology and chemistry) In cell biology, a vesicle is a structure within or outside a cell, consisting of liquid or cytoplasm enclosed by a lipid bilayer. Vesicles form naturally during the processes of secretion ( exocytosis ), uptake ( endocytosis ), and the transport of materials within the plasma membrane.
Release notes detail the corrections, changes or enhancements (functional or non-functional) made to the service or product the company provides.They might also be provided as an artifact accompanying the deliverables for System Testing and System Integration Testing and other managed environments especially with reference to an information technology organization.
A chemical substance is a unique form of matter with constant chemical composition and characteristic properties. [ 1][ 2] Chemical substances may take the form of a single element or chemical compounds. If two or more chemical substances can be combined without reacting, they may form a chemical mixture. [ 3]
According to Merriam-Webster and the Online Etymology Dictionary, the word "molecule" derives from the Latin "moles" or small unit of mass. The word is derived from French molécule (1678), from Neo-Latin molecula, diminutive of Latin moles "mass, barrier". The word, which until the late 18th century was used only in Latin form, became popular ...
In chemistry, reactivity is the impulse for which a chemical substance undergoes a chemical reaction, either by itself or with other materials, with an overall release of energy . Reactivity refers to: theories to predict and to account for these processes. The chemical reactivity of a single substance (reactant) covers its behavior in which it ...
Hemolysis or haemolysis ( / hiːˈmɒlɪsɪs / ), [ 1] also known by several other names, is the rupturing ( lysis) of red blood cells (erythrocytes) and the release of their contents ( cytoplasm) into surrounding fluid (e.g. blood plasma ). Hemolysis may occur in vivo or in vitro . One cause of hemolysis is the action of hemolysins, toxins ...
Exergonic reaction. An exergonic reaction (such as cellular respiration) is a reaction that releases free energy in the process of the reaction. The progress of the reaction is shown by the line. Activation energy (1) slows down the reaction. The change of Gibbs free energy ( ΔG) in an exergonic reaction (that takes place at constant pressure ...
A chemical bond is the association of atoms or ions to form molecules, crystals, and other structures. The bond may result from the electrostatic force between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds, or some combination of these effects.
