What else can I help you with?
Substances inside the plasma membrane are?
Plasma membrane in made up of phospholipid bilayer and proteins. It has a hydrophobic tail facin each other on the bilayer, and polar head that face outside to the polar environment. Proteins such as integral and peripheral proteins are presenting on the membarane.
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.
Explain what effect more cholesterol in the plasma membrane will have on the membrane?
Increasing cholesterol in the plasma membrane can make the membrane more rigid and less fluid. This can affect membrane permeability and the function of membrane proteins. Additionally, high levels of cholesterol can lead to the formation of lipid rafts, which can impact cell signaling pathways.
These are primary molecules making up plasma membranes in cells?
Phospholipids are the primary molecules that make up plasma membranes in cells. Other important molecules include cholesterol, glycolipids, and proteins. These components help maintain the structure and function of the plasma membrane.
What are the molecules in the plasma membrane made of?
phospholipids are the molecules that make up the plasma membrane and they are made of polar (hydrophilic) heads and 2 non-polar (hydrophobic) tails
What effect will an increase in cholesterol in the plasma membrane have on the overall structure and function of the membrane?
An increase in cholesterol in the plasma membrane can make the membrane more rigid and less fluid. This can affect the membrane's ability to allow substances to pass through and communicate with other cells. Overall, it may impact the membrane's structure and function by altering its flexibility and permeability.
What type of Phospholipids that make up the plasma membrane?
the one in plasma membrane
What is the the function of proteins in the plasma membrane?
The proteins of the plasma serve the function of acting as porins. Porins are channels control the transport of substances in and out of the cell, imparting the membrane its property of semipermeabililty. Also, proteins make up 60-70% of the plasma membrane and thus form the bulk of it. Besides, the proteins are also involved in some important cellular reations.
Explain the role of membrane carbohydrates in cell-cell recognition?
membrane carbohydrates are used for the selection of cells to make tissues, and the rejection of foreign cells (like in your blood). Cells recognize each other by binding to surface molecules, often carbohydrates, on the plasma membrane. Membrane carbohydrates may be covalently bonded to lipids of more commonly proteins (forming glycoproteins). Carbohydrates on the external side of the plasma membrane vary among species, individuals, and even cell types in an individual

What do you think will happen to the the cell if the plasma membrane does not function properly?
It will burst, or shrivel. The plasma membrane(Cell Membrane) manages what goes in and out. If it doesn't function properly, it will either take in too much water, take out too much water or make no changes. Takes in too much > Burst. Takes out too much > Shrivel. Stays the same > Eventually runs out of nutrients and dies.
Where does the protein to make the plasma membrane?
that is found in a prokyotic cell
What is a double layer of these molecules that make up the plasma membrane?
