What else can I help you with?
Which type of molecule is found in the plasma membrane?
The plasma membrane is composed mostly of phospholipids
What protein acts like stiffner in microvilli?
Integral protein. They wedge themselves into the phospholipids that make up part of the plasma membrane. The other type of protein is peripheral protein but it sits on the outside of the membrane.
What type of bilomolecuels make up a cell membrane bi layer?
phospholipids and proteins
How are phospholipids oriented in the plasma membrane?
The plasma membrane and other membranes of a cell are composed mostly of proteins and a type of lipid called phospholipids. A phospholipids molecule is structured with two fatty acids. The two fatty acids at one end (the tail) of the phospholipids are hydrophobic (not attracted to water). The other end (the head) of the molecule includes a phosphate group, which is negatively charged and hydrophilic (attracted to water). Thus, the tail end of a phospholipids is pushed away by water, while the head is attracted to water.
What is the most common type of phospholipids in the cell membrane of nerve cells?
The most common type of phospholipids in the cell membrane of nerve cells are phosphatidylcholine and phosphatidylethanolamine, which together make up a majority of the lipid bilayer. These phospholipids help maintain the structural integrity and fluidity of the cell membrane, which is crucial for proper nerve cell function.
What molecules make up the bi layer of a cell membrane?
Phospholipids lay to the foundation. They are type of lipids.
What cell membrane type of cell?
Both prokaryotic and eukaryotic cells have a plasma membrane, a double layer of lipids that separates the cell interior from the outside environment. This double layer consists largely of specialized lipids called phospholipids.
Which type of cells are surrounded by a plasma membrane made of two layers of phosphilipids and integrated proteins?
All living eukaryotic cells are surrounded by a plasma membrane made of two layers of phospholipids and integrated proteins. Prokaryotic cells also show this structure, but have additional layers of peptidoglycan and occasionally lipoproteins.
Which of the following incorrectly matches the type of cell type of protein and site of the proteins synthesis?
prokaryote, plasma membrane protein, ribosome bound to plasma membrane
What type of membrane does the cell have?
It is a bi-layer of phospholipids, also called the 'phospholipid bilayer'.
What type of molecule makes up the bi-layer of a cell membrane?
This membrane is called the fluid mosaic model as it is a mixture of phospholipids, cholesterol, proteins and carbohydrates. Most of the membrane is composed of phospholipid molecules. These allow the membrane to be rather fluid.Embedded in this membrane are proteins which give some structure to the membrane. The 3rd components are proteins or glycolipids. Cholesterol is also found in the membrane. It prevents lower temperatures from inhibiting the fluidity of the membrane and prevents higher temperatures from increasing fluidity.
What type of membrane is membrane plasma?
The plasma membrane is a phospholipid bilayer membrane that surrounds the cell, serving as a protective barrier. It is selectively permeable, allowing certain molecules to enter and exit the cell. The plasma membrane also contains proteins that help with cell communication and transport.
