What else can I help you with?
What organelle synthesizes steroids in the ovary and stores calcium in muscle cells?
Smooth ER
The major role of the sarcoplasmic reticulum is to regulate?
The major role of the sarcoplasmic reticulum is to regulate calcium levels in muscle cells. It stores and releases calcium ions during muscle contraction and relaxation, playing a crucial role in muscle function.
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 control the amount of calcium in the body?
calcitonin (thyroid) used to break down calcium stores in the bone. and parathormone (parathyroid) - stores the excess calcium in the bones
Why would drinking milk help the muscular system?
Milk is a rich source of protein, which is essential for muscle growth and repair. It also contains calcium and other nutrients that support overall muscle function. Drinking milk after a workout can help replenish glycogen stores and promote muscle recovery.
What structure of skeletal muscle functions stores calcium?
sarcoplasmic reticulum
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.
What stores calcium important in muscle contractions?
The Sarcoplasmic Reticulum stores calcium and releases it through the terminal cisternae into the tubule.
What is the organelle that stores calcium in resting muscle cells?
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.
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.
What organelle synthesizes steroids in the ovary and stores calcium in muscle cells?
Smooth ER
What are calcium ions stores as in muscle cells?
sarcoplasmic reticulum, i think. either that are T tubules
When a muscle cell responds to a stimulus calcium is released from the?
When a muscle cell responds to a stimulus, calcium is released from the sarcoplasmic reticulum. This calcium binds to troponin, triggering a conformational change that allows myosin to bind to actin and initiate muscle contraction.
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 similar to ER but collects and stores calcium ions in a resting muscle cell?
sarcoplasmic reticulum (SR)
During contraction of the heart muscle cells?
some calcium enters the cell from the extracellular space and triggers the release of larger amounts of calcium from intracellular stores
The major role of the sarcoplasmic reticulum is to regulate?
The major role of the sarcoplasmic reticulum is to regulate calcium levels in muscle cells. It stores and releases calcium ions during muscle contraction and relaxation, playing a crucial role in muscle function.
