The lipid bilayer surrounding the lysosome and separating its contents from the cell cytoplasm.

A lysosome before it has fused with a vesicle or vacuole.

Vacuole formed by the fusion of a lysosome with an organelle (autosome) or with a primary phagosome.

A membrane-bound organelle that carries materials newly ingested by endocytosis. It passes many of the materials to lysosomes for degradation.

Small irregularly shaped intracellular vesicles to which endocytosed molecules are initially delivered.

The enzymatic release of energy from organic compounds (especially carbohydrates and fats) which requires oxygen as the terminal electron acceptor.

The enzymatic release of energy from organic compounds (especially carbohydrates and fats) which uses compounds other than oxygen (e.g. nitrate, sulfate) as the terminal electron acceptor.

respiratory chain complex III (sensu Eukaryota)

ubiquinol-cytochrome-c reductase complex (sensu Eukaryota)

A part of the respiratory chain, containing about 10 polypeptide subunits including four redox centers: cytochrome b/b6, cytochrome c1 and an 2Fe-2S cluster. Catalyzes the oxidation of ubiquinol by oxidized cytochrome c1. As in, but not restricted to, the eukaryotes (Eukaryota, ncbi_taxonomy_id:2759).

The breakdown into simpler components of a fatty acid, any of the aliphatic monocarboxylic acids that can be liberated by hydrolysis from naturally occurring fats and oils. Fatty acids are predominantly straight-chain acids of 4 to 24 carbon atoms, which may be saturated or unsaturated; branched fatty acids and hydroxy fatty acids also occur, and very long chain acids of over 30 carbons are found in waxes.

respiratory chain complex IV (sensu Eukaryota)

cytochrome c oxidase complex (sensu Eukaryota)

A part of the respiratory chain, containing the 13 polypeptide subunits of cytochrome c oxidase, including cytochrome a and cytochrome a3. Catalyzes the oxidation of reduced cytochrome c by dioxygen (O2). Found in eukaryotes. As in, but not restricted to, the eukaryotes (Eukaryota, ncbi_taxonomy_id:2759).
