Structure of a Phospholipid Molecule A phospholipid is an amphipathic molecule which means it has both a hydrophobic and a hydrophilic component.

. A single phospholipid molecule has a phosphate group on one end called the head and two side-by-side chains of fatty acids that make up the lipid tails. This is because there are proteins inside the cell membrane that help stop things from getting in that arent supposed. Which statement best describes the structure of a lipid molecule.

Phospholipid Molecule Structure Source. Phospholipids consist of a glycerol molecule two fatty acids and a phosphate group that is modified by an alcohol. The head and the tail.

Answered Dec 14 2018. Which of the following describes the structure of a phospholipid. A single phospholipid molecule has two different ends.

Each phospholipid has a hydrophilic head and a hydrophobic tail. These groups are polar and are attracted to water. A non polar molecule attached to fatty acid.

The bilayers structure causes the membrane to be semi-permeable. The tail end is made up of two strings of hydrogen and carbon atoms called fatty acid chains. Correct answer - What best describes the structure of a phospholipid.

The non-polar heads are on the surfaces of the membrane and the. How is a cell membrane plasma membrane like a castle wall. Some species use three fatty acid chains but two is most common.

The phospholipid molecules forms micelles when placed in water. The phospholipid is composed of a glycerol molecule and tow fatty acid chains. Proteins embedded in two layers of phospholipid a layer of protein coating a layer of phospholipid phospholipids sandwiched between two layers of protein proteins sandwiched between two layers of phospholipid.

What best describes the structure of a phospholipid. According to Biologists the best sentence that describes the general structure of a cell membrane is proteins that are embedded in two layers of phospholipids. The phospholipid structure made by budding yeast before celll division a membranous sac containing organic molecules that interact with one another the structure that contains nucleic acids in prokaryotes a spontaneously formed lipid monolayer in an aqueous solution.

Phospholipids make up the basic structure of a cell membrane. Describe the structure of a phospholipid and explain which regions of the phospholipid are hydrophobic and which are hydrophilic. A phospholipid has a charged head and an uncharged tail.

Proteins sandwiched between two layers of phospholipids A and proteins embedded into a layer of phospholipids B. The fatty acid chains are the uncharged nonpolar tails which are hydrophobic. Plasma membrane is the outer covering of all the cells but only in a plant cell it is present below the cell wall.

The hydrophilic head consists of a glycerol molecule bound to a phosphate group. It is the main part of cell membranes. As portrayed in the diagrammatic illustration above the glycerol molecule and the phosphate group makes up the hydrophilic head or the water-loving part of the phospholipid.

The hydrophobic tails face inward towards one another and the hydrophilic heads face outwards. Which best describes the structure of a phospholipid. A non polar molecule attached to fatty acid b.

It is composed of phospholipid bilayer structure with embedded proteins. Da phosphate molecule joined to a fatty acid. There are two answers here that would work best.

The phosphate group is the negatively-charged polar head which is hydrophilic. The phospholipid bilayer is made of two layers of phospholipids. The walls of a castle like the cell membrane are designed to keep out dangerous things.

The phospholipid is an amphiphatic molecule having hydrophobic tail and hydrophilic head. Which statement best describes the structure of a phospholipid. Chapter 4 Cell Transport Learning Objectives Describe the structure and properties of a phospholipid and a phospholipid bilayer.

Biology questions and answers. The fatty acid chains are uncharged and non-polar while the phosphate head is polar and negatively charged. This means that it likes or is attracted to water molecules.

Which of the statements best describes a protocell. A lipid is made up of a. Which of the following best describes the general structure of a cell membrane.

A phospholipid consists of two basic parts. It is a diglyceride - a glycerol with two fatty acid tails What kind of bond or attraction holds the two halves of the phospholipid bilayer together. Are amphipathic double-charged molecules composed of one glycerol molecule one phosphate group and two fatty acid units.

A head and a tail. A glycerol molecule between two. The second group the hydrophobic tail consists of two fatty acid chains.

A glycerol molecule between two fatty acids. Distinguish between hydrophilic and hydrophobic. Each phospholipid is amphipathic with two hydrophobic tails and a hydrophilic head.

The head end contains a phosphate group and is hydrophilic. The membrane proteins help in transportation of water ions and solute across the membrane and thus provide semi permeability to the membrane. A There are two layers of phospholipids.

Bickis Corporate employee MBA Stockton. A There are two layers of phospholipids. What characteristics of phospholipids causes Semipermeability of the cell membrane.

A lipid molecule with polar head an tail. Which best describes the structure of the phospholipids of the lipid bilayer.
