Smooth Endoplasmic Reticulum
Captions available
The idea
The smooth ER is continuous with the rough ER but carries few or no ribosomes, and instead synthesizes lipids and steroid hormones, detoxifies chemicals, and stores calcium.
In practice
In 1960s electron-microscopy studies of adrenal cortex cells, researchers linked their calcium-storing smooth ER to steroid hormone synthesis.
Where people slip
Rough and smooth ER are one continuous system, distinguished by function, not separate organelles.
