What is the carbohydrate chain projecting from the plasma membrane involved in?
The carbohydrate chain projecting from the plasma membrane, often referred to as a glycoprotein or glycolipid, plays a crucial role in cell recognition, signaling, and adhesion. These chains can facilitate communication between cells, help in immune responses by identifying self versus non-self cells, and contribute to the structural stability of the cell membrane. Additionally, they can serve as receptors for various signaling molecules, influencing cellular responses and interactions.
What membrane protein has sugars attached to itself and helps cells recognize self?
Glycoproteins are membrane proteins that have sugars attached to themselves. These sugars play a role in cell recognition by helping cells identify "self" molecules from non-self molecules.
Which molecules in the plasma membrane provide cell identity?
Cell identity is primarily provided by glycoproteins and glycolipids in the plasma membrane. These molecules have carbohydrate chains that extend from their surfaces, forming unique markers that can be recognized by other cells and the immune system. This recognition is crucial for processes such as cell communication, tissue formation, and immune responses. Additionally, these markers help distinguish between self and non-self cells, playing a key role in immune function.
If a tiny hole is made in a plasma membrane it usually heals immediately and no harm results What property of the plasma membrane allows this?
The property that allows the plasma membrane to heal immediately after a tiny hole is its self-sealing nature due to its fluidity and flexibility. The lipid bilayer structure of the plasma membrane can rapidly rearrange to close small breaches, maintaining the barrier function of the membrane.
What makes it possible for the plasma membrane to self assemble?
The plasma membrane is able to self-assemble due to the properties of its constituent molecules, such as phospholipids. Phospholipids have hydrophilic heads and hydrophobic tails, which drives them to form a bilayer structure when exposed to water. This spontaneous assembly is driven by the hydrophobic effect and results in the formation of a stable and selectively permeable membrane.

What structural component of a cell membrane is involved when a cell is recognized as belonging to a specific tissue?
Glycoproteins and glycolipids are involved in cell recognition within specific tissues. These molecules, which are carbohydrates attached to proteins or lipids on the cell membrane, help cells communicate with each other and identify self from non-self.
An animal cell lacking oligosaccharides on the external surface of its plasma membrane would likely be impaired in which function?
Cell-cell recognition and communication would likely be impaired in an animal cell lacking oligosaccharides on the external surface of its plasma membrane. Oligosaccharides help cells recognize self from non-self, facilitate cell adhesion, and play a role in immune responses.

Function of recognition proteins?
Recognition proteins are involved in identifying and binding to specific molecules or cells. They play a key role in immune responses, cell signaling, and cell-cell interactions. In the immune system, recognition proteins help differentiate between self and non-self molecules.
What is the composition and function of each structure of the plasma membrane?
it is mostly water with many dissolved solute such as: nutrient, gases, hormones and wastes. Most plasma protein are produced by the liver. Albumin which is 60% of plasma protein serves as blood buffer to plasma osmotic pressure( the pressure that helps to keep water in the bloodstream). Another function of is plasma distribute heat.
What is a membrane protein with carbohydrates attached that helps cells identify self and plays a role in blood types organ transplants and germ recognition?
glycoproteins
What gives the plasma membrane the ability to self-reassemble?
Hydrophilic end
Do carbohydrates bind to the outside of cell membrane?
Yes they can be bonded to the outside of cell membranes. The carbohydrates located on the cell membrane are there to help the cell in cell recognition to determine whether a particle close to it is one that it needs to have within it or one that it does not need or that could be potentially harmful to it. They have a specific orientation with the outer layer of the cell membrane to help more fully with the recognition of "self" vs. "other"
