1
A gradient of electrochemical potential, usually for an ion that can move across a membrane.
2
The collective term for all possible frequencies of electromagnetic radiation.
3
A chemical entity that accepts electrons transferred to it from another compound. It is an oxidizing agent that, by virtue of its accepting electrons, is itself reduced in the process.
4
Any of various molecules that are capable of accepting one or two electrons from one molecule and donating them to another in the process of electron transport.
5
A microbially facilitated process of nitrate reduction (performed by a large group of heterotrophic facultative anaerobic bacteria) that may ultimately produce molecular nitrogen.
6
The process of reversing the charge across a cell membrane (usually a NEURON), so causing an ACTION POTENTIAL.
7
A process in which proteins or nucleic acids lose the quaternary structure, tertiary structure and secondary structure which is present in their native state.
8
Efferent: Conducted or conducting outwards or away from something (for nerves, the central nervous system; for blood vessels, the organ supplied). Egg:
9
Also known as a macula adhaerens, is a cell structure specialized for cell-to-cell adhesion
10
Means "falling off at maturity" or "tending to fall off", and it is typically used in order to refer to trees or shrubs that lose their leaves seasonally (most commonly during autumn).
11
A short branched extension of a nerve cell, along which impulses received from other cells at synapses are transmitted to the cell body
12
An organ or cell that acts in response to a stimulus.
13
Conducted or conducting outwards or away from something (for nerves, the central nervous system; for blood vessels, the organ supplied).
14
A subatomic particle with a negative elementary electric charge.
15
A unit of mass (also known as an atomic mass unit, amu), equal to the mass of a hydrogen atom (1.67 x 1024 g).
16
The female reproductive cell (gamete) in oogamous organisms.
