What else can I help you with?
The polar end of the phospholipid plasma membrane is . hydrophilic hydrophobic?
"philic" ( likes water)
Is the polar end of the phospholipid plasma membrane hydrophobic or hydrophilic?
The polar end of a phospholipid in the plasma membrane is hydrophilic, meaning it is attracted to water. This hydrophilic end faces outward towards the aqueous environment both inside and outside the cell.
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 is the difference between diffusion of hydrophobic substances in comparison to hydrophilic ones across the plasma membrane?
the hydrophilic easier than hydrophobic substances
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 is the structure of a plasma membrane and what is the role of their hydrophilic heads?
That is the structure of plasma membrane adjectent or near the secondary cell wall in a cells. It's a living outermost boundary of all the cells.
What indicates how easy it is for a substance to cross the plasma membrane?
Whether it's charged or not, hydrophilic, hydrophobic and its size.
Three major parts of the cell membrane?
The three major parts of the cell membrane are phospholipid bilayer, proteins, and cholesterol. The phospholipid bilayer forms the basic structure of the membrane, while proteins play various roles such as transport, signaling, and cell recognition. Cholesterol helps to maintain the stability and fluidity of the membrane.
What parts of the plasma membrane are water soluble?
The plasma membrane is made of phospholipids. Phospholipids contain a hydrophillic head group which is considered water soluable. They also contain a hydrophobic tail group whichi s considered lipid soluable
What is in the center of the plasma membrane?
The lipid tails are found in the centre of the membrane. The membrane is made out of phospholipids. These have a phosphate head which is hydrophilic and a lipid tail that is hydrophobic. This form a bilayer (double-layer).
What part of the plasma membrane is hydrophilic?
The plasma membrane is a dynamic structure. It is composed of 2 layers of lipid material with protein molecules interspersed through out. The phospholipids move at a rate of 2um. /sec. while the proteins move at a much slower rate. The phospholipids have 2 definite ends, a hydrophilic (focusing to the outside and inside of the membrane) and a hydrophobic one (forming the center of the membrane
What molecules add support to plasma membrane?
Cholesterol molecules help to stabilize the plasma membrane by regulating its fluidity and flexibility. Additionally, glycolipids and glycoproteins on the outer surface of the membrane can contribute to cell adhesion and recognition. Proteins embedded in the membrane, such as integrins, also provide structural support and help with cell signaling.
