Do muscle cells use active transport?
Muscle cells can use both fatty acids and glucose for their aerobic respiration. ATP is used for two things in muscle cells: active transport of calcium (Ca++) and movement of motor proteins.
Which cell is showing active transport?
Examples of active transport include: uptake of glucose by epithelial cells in the villi of the small intestine. uptake of ions from soil water by root hair cells in plants.
Is ATP needed for endocytosis?
Endocytosis methods require the direct use of ATP to fuel the transport of large particles such as macromolecules; parts of cells or whole cells can be engulfed by other cells in a process called phagocytosis. The cell expels waste and other particles through the reverse process, exocytosis.
What is the difference between endocytosis and exocytosis?
Endocytosis is the process of capturing a substance or particle from outside the cell by engulfing it with the cell membrane, and bringing it into the cell. Exocytosis describes the process of vesicles fusing with the plasma membrane and releasing their contents to the outside of the cell.
What do muscle cells need to contract?
Muscles cannot contract on their own. They need a stimulus from a nerve cell to “tell” them to contract. The motor neurons, in turn, stimulate muscle fibers in your arm and shoulder to contract, causing your arm to rise. Involuntary contractions of cardiac and smooth muscles are also controlled by nerves.
Where does active transport take place in the cell?
Active transport of small molecular-size material uses integral proteins in the cell membrane to move the material—these proteins are analogous to pumps. Some pumps, which carry out primary active transport, couple directly with ATP to drive their action.
What kind of muscle looks like under the microscope?
Muscle structure – muscle under the microscope. 1 Skeletal muscle. Skeletal muscle looks striped or “striated” – the fibres contain alternating light and dark bands (striations) like horizontal 2 Cardiac muscle. 3 Smooth muscle. 4 Looking closer at skeletal muscle. 5 Looking inside a muscle cell.
How is the energy stored in ATP used in active transport?
Active transport uses energy stored in ATP to fuel the transport. Active transport of small molecular-size material uses integral proteins in the cell membrane to move the material—these proteins are analogous to pumps. Some pumps, which carry out primary active transport, couple directly with ATP to drive their action.
Which is an example of an active transport mechanism?
Some active transport mechanisms move small-molecular weight material, such as ions, through the membrane. In addition to moving small ions and molecules through the membrane, cells also need to remove and take in larger molecules and particles.
