An uncoupler or uncoupling agent is a molecule that disrupts oxidative phosphorylation in prokaryotes and mitochondria or photophosphorylation in chloroplasts and cyanobacteria by dissociating the reactions of ATP synthesis from the electron transport chain.
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
A common laboratory-scale mechanical method for cell disruption uses glass, ceramic, or steel beads, 0.1–2 mm (0.004–0.08 in) in diameter, mixed with a sample suspended in an aqueous solution.
A comparison of the structures of the natural estrogen hormone estradiol (left) and one of the nonyl-phenols (right), a xenoestrogen endocrine disruptor. Endocrine disruptors, sometimes also referred to as hormonally active agents, [1] endocrine disrupting chemicals, [2] or endocrine disrupting compounds [3] are chemicals that can interfere with endocrine (or hormonal) systems.

In cell biology, a biological pathway is a series of interactions among molecules in a cell that leads to a certain product or a change in the cell. Such a pathway can trigger the assembly of new molecules, such as a fat or protein.
Also called functionalism. The Darwinian view that many or most physiological and behavioral traits of organisms are adaptations that have evolved for specific functions or for specific reasons (as opposed to being byproducts of the evolution of other traits, consequences of biological constraints, or the result of random variation). adaptive radiation The simultaneous or near-simultaneous ...
Although the term "insect growth disruptor" more accurately describes the actions of IGRs, it did not become widely used. [1] IGRs encompass chemical classes with three modes of action ( mechanisms of action ): juvenile hormone analogs, chitin synthesis inhibitors, and ecdysone receptor agonists.
Teratology is the study of abnormalities of physiological development in organisms during their life span. It is a sub-discipline in medical genetics which focuses on the classification of congenital abnormalities in dysmorphology caused by teratogens and also in pharmacology and toxicology.
