What else can I help you with?
Is the concentration of calcium ion greater in the sarcoplasmic reticulum or sarcoplasm of a resting muscle?
The concentration of calcium ion is greater in the sarcoplasmic reticulum compared to the sarcoplasm of a resting muscle. This is because the sarcoplasmic reticulum stores and releases calcium ions during muscle contraction.
What is immediate source of calcium ion for muscle fiber?
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.
Normally stored in the terminal cisternae of the sarcoplasmic reticulum?
Calcium ions are normally stored in the terminal cisternae of the sarcoplasmic reticulum in muscle cells. When muscle contraction is initiated, these stored calcium ions are released into the cytoplasm, triggering muscle contraction.
Which organelle stores calcium and is considered the cell's membrane factory?
The endoplasmic reticulum is the organelle that stores calcium and is considered the cell's membrane factory. It plays a crucial role in protein and lipid synthesis as well as detoxification processes in the cell.
What structure in skeletal mucle cells functions in calcium storage?
The structure within skeletal muscle cells responsible for calcium storage is the sarcoplasmic reticulum. It stores and releases calcium ions, which are crucial for muscle contraction and relaxation. When a muscle cell receives a signal to contract, calcium is released from the sarcoplasmic reticulum, allowing the muscle to shorten and generate force.
Organelle storing calicium in resting skeletal muscle fibers?
The organelle responsible for storing calcium in resting skeletal muscle fibers is the sarcoplasmic reticulum (SR). It releases calcium ions when muscle contraction is initiated by a nerve impulse. Calcium is essential for muscle contraction as it acts as a trigger for muscle fiber activation.
What organelle synthesizes steroids in the ovary and stores calcium in muscle cells?
Smooth ER

What is similar to ER but collects and stores calcium ions in a resting muscle cell?
sarcoplasmic reticulum (SR)

What organelle stores calcium in muscles cells?
The smooth endoplasmic reticulum.
What stores calcium important in muscle contractions?
The Sarcoplasmic Reticulum stores calcium and releases it through the terminal cisternae into the tubule.
What structure of skeletal muscle functions stores calcium?
sarcoplasmic reticulum

What are calcium ions stores as in muscle cells?
sarcoplasmic reticulum, i think. either that are T tubules
