Is phospholipids are polarized molecules?
no
What molecules form the double layer of cell membranes?
A double layer of phospholipids makes up most of your cell membranes
What are the two principal types of molecules in plasma membranes?
phospholipids and proteins.
What 2 kinds of molecules are important in making cell membranes?
A phosphate group and a lipid (to form a phospholipid).
The fatty acid tail region of the phospholipids prevent soluble molecules from entering the cell?
Water
Is phospholipids are polarized molecules?
no
A form of diffusion in which the molecules pass through a protein instead of between the phospholipids is called?
Glucose molecules are molecules that pass through a protein instead of between the phospholipids. This is because they are to big to diffuse through phospholipids.
What type of molecules are phospholipids?
lipids
What are most of the molecules that compose the plasma membrane?
phospholipids
Are Phospholipids nonpolar molecules true or false?
False
Is vacuoles composed of phospholipids and other embedded molecules?
Yes, a vacuole is made up of phospholipids and other embedded molecules. The vacuole is also known as a cell membrane.
What molecules form much of the cell membrane?
The cell membrane is composed mainly of lipids. Phospholipids to be precise.
What substance in the cell membrane keeps it from breaking too easily?
Phospholipids and cholesterol.
Phospholipids are polarized molecules true or false?
Firstly, they are lipids. They have a non-polar / hydrophobic tail and a polar / charged / acid / hydrophyllic head. The charged acid head is enhanced in its capabilities by the addition of a phosphate [PO4--] group. Reported to be crucial to brain functions and available in nutmeat, this makes peanuts equal to 'brain-food'.
How phosphorus is useful?
Metabolic molecules (ATP) Structure (phospholipids)
What molecules form the double layer of cell membranes?
A double layer of phospholipids makes up most of your cell membranes
Are phospholipids hydrophilic molecules?
Yes. They have a hydrophillic head and a hydrophobic tail.
