The cytoplasm of a skeletal muscle fiber is called the?
Sarcoplasm
What are the specific terms for plasma membrane and cytoplasm of muscle cell?
Plasma membrane of a muscle cell is called sarcolemma, while the cytoplasm is referred to as sarcoplasm.
What transports calcium out of the sarcoplasm?
The sarcoplasmic reticulum pumps calcium out of the sarcoplasm. This process is regulated by proteins such as SERCA (sarcoplasmic reticulum Ca2+-ATPase).
What is the function of the sarcoplasm?
The sarcoplasm is the cytoplasm or intracellular fluid of a muscle cell. It has many functions in acting as a medium for various cellular reactions to take place which are necessary for muscle contraction and general cellular metabolism.
What part of the muscle cell contains myofibrils?
The sarcoplasm
Do Skeletal muscle cells contain myoglobin?
Yes, in their sarcoplasm.
The process of nuclear division which creates two new identical nuclei is called?
The process of nuclear division that creates two new identical nuclei is called mitosis. During mitosis, the duplicated chromosomes are separated into two identical sets and distributed into separate nuclei.
What is the function of the calcium in the sarcoplasm?
Calcium in the sarcoplasm plays a crucial role in muscle contraction. It binds to troponin, initiating a cascade of events that ultimately leads to the exposure of binding sites on actin, allowing myosin to bind and generate muscle force.
Electrons are distributed evenly over an molecule?
In a molecule, electrons are not evenly distributed; they are typically found around the atomic nuclei in specific regions called electron clouds. These electron clouds are influenced by the presence of other atoms and their nuclei within the molecule, leading to areas of higher and lower electron density. This uneven distribution of electrons forms the basis of chemical bonding and reactivity in molecules.
How are the nuclei distributed within skeletal muscle cells and what role do they play in muscle function?
The nuclei in skeletal muscle cells are located on the periphery, near the cell membrane. These nuclei are important for controlling protein synthesis and cell repair in muscle cells. They play a crucial role in regulating muscle growth, repair, and adaptation to exercise.
Where is the sarcoplasm found?
The sarcoplasm is found within muscle cells, specifically in the cytoplasm. It surrounds the myofibrils and other organelles within the muscle cell and plays a crucial role in various cellular processes related to muscle contraction and metabolism.
A fluid-filled sac that acts as a lubricating structure for muscle movement is a?
"sarcoplasm"
