Which cell structure does phospholipid affect the function of?
The cell membrane and the membranes of all of their organelles are made of phospholipids.
What is the structure of a cell membrane in plant cells?
The cell membrane is composed of phospholipid bi-layer and proteins. The phospholipids are both hydrophillic and hydrophobic and makes the cell membrane be selectively permeable, that is allows only curtain molecules to pass through the membrane. The proteins function is to determine wchich molecules must go in and wchich shouldn't go inside the cell.
Why is the model of a membrane shown in the transperency referred to as the fluid mosaic model?
The membrane is made out of several molecules - mainly phospholipids. Instead of being a rigid structure, the molecules within the membrane are constantly moving and changing places. This means the membrane appears like a fluid.
What is the purpose of cholesterol in a membrane?
Cholesterol helps stabilize the membrane at warm temperatures, but also helps keep the membrane fluid at lower temperatures.
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 2 fat-based molecules make up part of the structure of the plasma membrane?
phospholipid and cholesterol
Which cell structure does phospholipid affect the function of?
The cell membrane and the membranes of all of their organelles are made of phospholipids.
What molecules form much of the cell membrane?
The cell membrane is composed mainly of lipids. Phospholipids to be precise.
. The inside of a membrane bilayer is .?
The cell membrane's bilayer structure is made up of phospholipids.
What are most of the molecules that compose the plasma membrane?
phospholipids

Are phospholipid molecules found in the cell membrane?
Yes. A specific example, peanuts are considered Brain Food because they contain phospholipids, and this indicates that phospholipids are needed for healthy brain cell membrane function. Anyone with more polish to add to this?
A double layer of these molecules makes up the plasma membrane?
A double layer of phospholipids makes up the plasma membrane.
What 2 molecules make up the cell membrane?
The plasma membrane is flexible and is made up of organic molecules called lipids and proteins .
What is a double layer of these molecules that make up the plasma membrane?
Phospholipids.
What is a Double layer of molecules that makes up the plasma membrane?
Phospholipids.
