genome
In modern molecular biology and genetics, a genome is the genetic material of an organism
adenosine triphosphate
Adenosine triphosphate is a nucleoside triphosphate, a small molecule used in cells as a coenzyme
eukaryote
A eukaryote is any organism whose cells contain a nucleus and other organelles enclosed within membranes
adhesin
Adhesins are cell-surface components or appendages of bacteria that facilitate adhesion or adherence to other cells or to surfaces
pili
A pilus is a hair like appendage found on the surface of many bacteria
plasmids
A plasmid is a small DNA molecule within a cell that is physically separated from a chromosomal DNA and can replicate independently
oxidative phosphorylation
Oxidative phosphorylation is the metabolic pathway in which cells use enzymes to oxidize nutrients, thereby releasing energy which is used to reform ATP
flagellum
A flagellum is a lash-like appendage that protrudes from the cell body of certain prokaryotic and eukaryotic cells
ATP synthase
ATP synthase is an important enzyme that creates the energy storage molecule adenosine triphosphate
