Eukaryotic organisms encompass a range of organisms, from humans to single-celled microorganisms such as protozoa. Eukaryotes are fundamentally different from prokaryotic microorganisms, such as bacteria, in their size, structure and functional...

The Eukaryota are one of the two major groups of biological organisms. The other is the Prokaryota, which contains the eubacteria and archae-bacteria. The key feature of all eukaryotes is that they possess eukaryotic cells. These differ from...

Basidomycetes are a fungal group belonging to the Eukarya domain, which includes all life forms composed by nucleated cells. Basidomycetes are classified under the Fungi kingdom as belonging to the phylum -mycota (i.e., Basidomycota or Basidiomycota),...

Eukaryotae, or eukaryotic cells, are large and complex cells bounded by an outer plasma membrane. They contain many organelles within their cytoplasm and a nucleus separated from the cytoplasm by the nuclear membrane. Fossils of eukaryotic cells are...

Animals, plants, fungi, and protists are eukaryotes (IPA: /juːˈkærɪɒt/), organisms whose cells are organized into complex structures by internal membranes and a cytoskeleton. The most characteristic membrane-bound structure is the nucleus. This...

Lipopolysaccharide is a component of the outer membrane of gram-negative bacteria and is the principal mediator of gram-negative bacterial toxicity to animals. Toxicity is mediated by lipid A, the membrane-forming element of lipopolysaccharide. Although usually thought to be restricted to prokaryotes, recent evidence...

Summary Eukaryotic cytochrome c oxidase (CcO), the terminal component of the mitochondrial electron transport chain is a heterooligomeric complex that belongs to the superfamily of heme-copper containing terminal oxidases. The enzyme, composed of both mitochondrially and nuclear encoded subunits, is embedded in the...
