What Carrier Proteins Transport Glucose Into A Muscle Cell?
carrier proteins transport glucose into a muscle cell
Carrier proteins transport glucose into a muscle cell.?
carrier proteins transport glucose into a muscle cell
How do muscle cells move?
the function of a muscle cell is, by definition, to move. this can be accomplished when the cell contracts. contracting makes it denser, which is why when you feel a relaxed muscle in your arm suddenly tense up, it hardens.A muscle cell expands and contracts in order to allow the human body to control the movement of it's limbs.
How does DNA direct a cell to become a muscle cell or a stomach cell?
I need this answer too, im pretty sure its beaccause the DNA acts as a set of instructions that tells the cell how to build itself and what proteins to make??
How can smooth muscle contract if it has no striation or sarcomeres?
Actin and myosin are present in all three muscle types. In skeletal and cardiac muscle cells, these proteins are organized in sarcomeres, with thin and thick filaments. The internal organization of a smooth muscle cell is very different: • A smooth muscle fibre has no T tubules, and the sarcoplasmic reticulum (SR) forms a loose network throughout the sarcoplasm. Smooth muscle tissue has no myofibrils or sarcomeres. As a result, this tissue also has no striations and is called nonstriated muscle. • Thick filaments are scattered throughout the sarcoplasm of a smooth muscle cell. The myosin proteins are organized differently than in skeletal or cardiac muscle cells, and smooth muscle cells have more cross-bridges per thick filament. • The thin filaments in a smooth muscle cell are attached to dense bodies, structures distributed throughout the sarcoplasm in a network of intermediate filaments composed of the protein desmin. Some of the dense bodies are firmly attached to the sarcolemma. The dense bodies and intermediate filaments anchor the thin filaments such that, when sliding occurs between thin and thick filaments, the cell shortens. Dense bodies are not arranged in straight lines, so when a contraction occurs, the muscle cell twists like a corkscrew. • Adjacent smooth muscle cells are bound together at dense bodies, transmitting the contractile forces from cell to cell throughout the tissue. • Although smooth muscle cells are surrounded by connective tissue, the collagen fibres never unite to form tendons or aponeuroses as they do in skeletal muscles.
What is the thicker of the two sliding proteins in a muscle cell?
myosin
What Carrier Proteins Transport Glucose Into A Muscle Cell?
carrier proteins transport glucose into a muscle cell
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 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.
Carrier proteins transport glucose into a muscle cell.?
carrier proteins transport glucose into a muscle cell
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.
What are the longitudunal bundles in the cytoplasm of a skeletal muscle cell called?
the so called longitudinal bundles in the cytoplasm of a skeletal muscle are actually the muscle contractile proteins, namely actin and myosin.

What is the Role of the DNA molecule in cells?
DNA is much like the "brain" of the cell. It contains genes that produce proteins through transcription (DNA--->RNA) and translation (RNA---->protein). Proteins are what give a cell its function (i.e. turns it from a generic cell into a muscle cell). in a nutshell, it basically tells the cell what to do.
