Smooth ER
The endoplasmic reticulum (smooth ER) is the organelle that makes steroids in gland cells, regulates calcium in muscle cells, and breaks down toxins in liver cells. It is involved in lipid synthesis, calcium storage, and detoxification processes in various cell types.
The organelle that stores calcium in resting muscle cells is the sarcoplasmic reticulum. Calcium ions are released from the sarcoplasmic reticulum during muscle contraction to trigger muscle activity.
A calciosome is a sarcoplasmic reticulum-like organelle which is involved in intracellar calcium-handling by non-muscle cells.
Endoplasmic reticulum is the organelle that is responsible for synthesizing steroids in gland cells, regulating calcium in muscle cells, and detoxifying substances in liver cells. It consists of rough ER, involved in protein synthesis, and smooth ER, which aids in lipid metabolism and detoxification.
In eukaryotic cells which organelle contains DNA?
the cells nucleus
The immediate source of calcium ion for muscle fiber is the sarcoplasmic reticulum, a specialized organelle within muscle cells that stores and releases calcium ions in response to nerve signals. When a muscle cell is stimulated, calcium ions are rapidly released from the sarcoplasmic reticulum into the cytoplasm, triggering muscle contraction.

Mitochondria
The sarcoplasmic reticulum in muscle fiber corresponds to the endoplasmic reticulum in other cell types. The sarcoplasmic reticulum is a specialized type of endoplasmic reticulum found in muscle cells, and it plays a key role in calcium storage and release during muscle contraction.
