The breakdown into simpler components of steroids, compounds with a 1,2,cyclopentanoperhydrophenanthrene nucleus.

The breakdown into simpler components of cholesterol, cholest-5-en-3 beta-ol, the principal sterol of vertebrates and the precursor of many steroids, including bile acids and steroid hormones.

The breakdown into simpler components of progesterone, a steroid hormone produced in the ovary which prepares and maintains the uterus for pregnancy. Also found in plants.

vesicle targeting, to, from or within Golgi

vesicle targeting, to, from or within dictyosome

The process by which vesicles are directed to specific destination membranes during transport to, from or within the Golgi apparatus; mediated by the addition of specific coat proteins, including COPI and COPII proteins and clathrin, to the membrane during vesicle formation.

farnesyl diphosphate biosynthesis, mevalonate pathway

The pathway that converts actetate, in the form of acetyl-CoA, to farnesyl diphosphate (FPP) through a series of mevalonate intermediates. Farnesyl diphosphate is an important substrate for other essential pathways, such as biosynthesis of sterols.

The breakdown of proline into simpler components such as glutamate.

retrograde vesicle-mediated transport, Golgi to ER

retrograde transport, Golgi to endoplasmic reticulum

The directed movement of substances from the Golgi back to the endoplasmic reticulum, mediated by COP I vesicles.

The directed movement of substances within the Golgi, mediated by small transport vesicles. These either fuse with the cis-Golgi or with each other to form the membrane stacks known as the cis-Golgi reticulum (network).

primary follicle stage oogenesis (sensu Mammalia)

The stage in oogenesis when a single layer of cuboidal follicle cells surrounds the oocyte. The oocyte nucleus is large. As in, but not restricted to, mammals (Mammalia, ncbi_taxonomy_id:40674).

The directed movement of substances from the Golgi to other parts of the cell, including organelles and the plasma membrane, mediated by small transport vesicles..
