What else can I help you with?
What is the membrane that cover the outside surface of the femur?
The membrane that covers the outside surface of the femur is called the periosteum. It is a dense, fibrous membrane that serves as a protective layer for the bone and also plays a role in bone growth and repair.
Where in the cell can you find the cell membrane?
The cell membrane can be found surrounding the cell, serving as a protective barrier that separates the inside of the cell from its external environment.
A neuron has a positive charge on the outer surface of the cell membrane due in part to the action of an active transport system called the?
sodium-potassium pump. This pump moves sodium ions out of the cell and potassium ions into the cell, creating a positive charge on the outer surface of the membrane. This helps maintain the neuron's resting membrane potential and is essential for proper nerve cell function.
What are folds of the cell membrane on the free surface?
The folds on the free surface of a cell membrane are called microvilli. They increase the surface area of the cell membrane, allowing for greater absorption of nutrients and molecules. Microvilli are commonly found in cells that are involved in absorption, such as in the lining of the small intestine.
How are new proteins moved to the surface of the cells and secreted?
New proteins are moved to the cell surface and secreted through a process called vesicle trafficking. Proteins destined for the cell surface are synthesized by ribosomes attached to the endoplasmic reticulum, folded properly in the Golgi apparatus, and then packaged into vesicles for transport to the cell membrane for secretion. These vesicles fuse with the plasma membrane, releasing the proteins outside the cell.
What is the membrane that cover the outside surface of the femur?
The membrane that covers the outside surface of the femur is called the periosteum. It is a dense, fibrous membrane that serves as a protective layer for the bone and also plays a role in bone growth and repair.
How is the membrane structured?
Every cell membrane consists of phospholipid bi layer, specialized proteins, cholesterol and glycolipids.Every plasma membrane maintains a membrane resting potential across its surface. Sometimes clusters of cholesterol called lipid rafts are also found.
What is cell volume?
The volume is how much space is inside the cell. The ratio is the surface area divided by the volume. This indicates how much surface area is available compared to how big the cell is.
Where is the cell membrane on a ciliated epithelial cell?
The cell membrane of a ciliated epithelial cell is located on the outer surface of the cell. This membrane separates the cell's internal environment from the external environment and plays a crucial role in controlling the movement of substances in and out of the cell.
What molecules are on the outer surface of the plasma membrane?
The outside surface of the plasma membrane is made of a layer of molecules called phospholipids, which have hydrophobic and a hydrophilic parts. The hydrophilic parts are on the outside surface, attracted by the water and other hydrophilic molecules outside the cell. There are also proteins of various kinds attached to and embedded in this outer layer.
Where in the cell can you find the cell membrane?
The cell membrane can be found surrounding the cell, serving as a protective barrier that separates the inside of the cell from its external environment.
What controls the movement in and out of the cell in plant cells?
cell membrane aka plasma membrane
A neuron has a positive charge on the outer surface of the cell membrane due in part to the action of an active transport system called the?
sodium-potassium pump. This pump moves sodium ions out of the cell and potassium ions into the cell, creating a positive charge on the outer surface of the membrane. This helps maintain the neuron's resting membrane potential and is essential for proper nerve cell function.
What is the difference between cell surface membrane and plasma membrane?
The diffrence is that the cell membrane is just a barrier between the exterior enviroment and the interior of the cell, while the cell surface membrane exerts control over what enters/leaves the cell! :)
What the membrane on the surface of the lungs is called the?
The [mucosal] Pleural membrane.
What protein that projects from the outer surface of the membrane is termed?
The protein that projects from the outer surface of the membrane is termed as an extrinsic or peripheral membrane protein. These proteins are not embedded within the lipid bilayer but instead are attached to the surface of the membrane.
How are symmetric membrane any different from asymmetric membrane?
Symmetric membranes the diamter of pores is constant throughout the cross section of the membrane, as membrane thicknes causes drah to mass transfer. Where as asymmetric membranes the pore size at the surface have a different sixe compared with the holes at the bottom side. Large particles will not enter the the body of the membrane so plugging is avoided.
