concentration gradient — The change in solute concentration per unit distance in solute. Concentration gradients cause Fickian diffusion (spreading) of solutes from regions of highest to regions of lowest concentrations. In slowing moving ground water, this is the… … Lexicon of Cave and Karst Terminology
cell — cell1 cell like, adj. /sel/, n. 1. a small room, as in a convent or prison. 2. any of various small compartments or bounded areas forming part of a whole. 3. a small group acting as a unit within a larger organization: a local cell of the… … Universalium
Membrane potential — Differences in concentration of ions on opposite sides of a cellular membrane lead to a voltage called the membrane potential. Many ions have a concentration gradient across the membrane, including potassium (K+), which is at a high inside and a… … Wikipedia
Chemotaxis — is the phenomenon in which somatic cells, bacteria, and other single cell or multicellular organisms direct their movements according to certain chemicals in their environment. This is important for bacteria to find food (for example, glucose) by … Wikipedia
Cytosol — The cytosol is a crowded solution of many different types of molecules that fills much of the volume of cells.[1] The cytosol or intracellular fluid (or cytoplasmic matrix) is the liquid found inside cells, that is separated into compartments by… … Wikipedia
Resting potential — The relatively static membrane potential of quiescent cells is called the resting membrane potential (or resting voltage), as opposed to the specific dynamic electrochemical phenomena called action potential and graded membrane potential. Apart… … Wikipedia
nervous system — Anat., Zool. 1. the system of nerves and nerve centers in an animal or human, including the brain, spinal cord, nerves, and ganglia. 2. a particular part of this system. Cf. autonomic nervous system, central nervous system, peripheral nervous… … Universalium
Decompression (diving) — Divers decompressing in the water at the end of a dive Decompression in the context of diving derives from the reduction in ambient pressure experienced by the diver during the ascent at the end of a dive or hyperbaric exposure and refers to both … Wikipedia
Ultracentrifuge — The ultracentrifuge is a centrifuge optimized for spinning a rotor at very high speeds, capable of generating acceleration as high as 1,000,000 g (9,800 km/s²). There are two kinds of ultracentrifuges, the preparative and the analytical… … Wikipedia
Membrane technology — The membrane technology covers all process engineering measures for the transport of substances between two fractions with the help of permeable membranes. That means in general mechanical separation process for separation of gaseous or liquid… … Wikipedia
Hodgkin–Huxley model — Basic components of Hodgkin–Huxley type models. Hodgkin–Huxley type models represent the biophysical characteristic of cell membranes. The lipid bilayer is represented as a capacitance (Cm). Voltage gated and leak ion channels are represented by… … Wikipedia
