What chemical triggers sliding of muscle filaments?
The chemical that triggers the sliding of muscle filaments is calcium ions. When muscle cells receive a signal to contract, calcium ions are released into the muscle cell, binding to specific proteins and initiating the sliding mechanism between actin and myosin filaments in the muscle cells.

What Carrier Proteins Transport Glucose Into A Muscle Cell?
Glucose transport into muscle cells is primarily facilitated by the glucose transporter 4 (GLUT4) carrier protein. This transporter is insulin-responsive and plays a crucial role in regulating glucose uptake by muscle cells to meet energy demands during exercise and recovery.
What is the thin filament of the myocardial cell?
The thin filament of a myocardial cell is composed primarily of actin, tropomyosin, and troponin proteins. These proteins play a crucial role in regulating the contraction and relaxation of the heart muscle by interacting with the thick filament during the process of muscle contraction.
How does DNA direct a cell to become a muscle cell or a stomach cell?
DNA contains instructions for making different proteins that determine the function of a cell. When specific genes are turned on or off, it directs a cell to differentiate into a muscle cell or a stomach cell through a process called gene expression, where certain proteins are produced to give the cell its specialized function. Different combinations of gene expression lead to different cell types in the body.
What is the thicker of the two sliding proteins in a muscle cell?
myosin

Why does a cell need proteins?
Everything a cell does is the action of proteins - life is the result of protein's actions.
Does muscle cell has ribosomes?
Yes of course muscle cells have. They need to synthesize proteins
What are Micro-filaments?
ANSWERsolid rod of proteins thinner than a microtubule, that enables a cell to move or change shape
What is the main type of cell found in your muscle in your arm?
The main type of cell found in muscle tissue in your arm is the muscle cell, also known as a muscle fiber. These cells contain contractile proteins that allow for movement and contraction of the muscle.
What features do cell have?
muscle contain special proteins called contractile proteins, they contract and relax to cause movement. Muscles are generally of two types (1) voluntary muscle and (2) involuntary muscle.
What 2 proteins make up the mass of a muscle cell?
Actin and myosin interact in muscle cells.
What is the part of the muscle fiber that allows the fiber to contract?
The sacromere with the proteins actin and myosin allow the muscle cell (fiber) to contract.
Why are muscle cells round?
Muscle cells are cylindrical in shape, not round, in order to efficiently contract and generate force. This elongated shape allows for the alignment of contractile proteins along the length of the cell, facilitating the sliding filament mechanism that leads to muscle contraction. Additionally, the cylindrical shape maximizes the surface area available for the attachment of tendons and other muscle fibers.

What takes up most of a muscles cell volume and is the contractile component of a muscle cell?
The component that takes up most of a muscle cell's volume and is responsible for contraction is the myofibrils. These structures are composed of repeating units called sarcomeres, which contain the contractile proteins actin and myosin. When stimulated by a nerve impulse, these proteins interact to produce muscle contraction. Thus, myofibrils are essential for the muscle's ability to generate force and movement.
