a phosolipid bilayer makes up the plasma membrane. The bilayer forms because the hydrophobic regions (water hating) cling together and face inwards while the hydrophillic regions (water loving) attract each other and face the outside, water touching area. Lipids are amphiphillic, meaning they have both water loving, and water hating regions within its structure, allowing them to conform into a bilayer structure

∙ 11y agoLipid molecules occur in the form of quasi-static fluid state. They are constantly in the random motion. Also, they have charges on their surface. Thus, they are in a state that is the characteristic of Plasma. They are called as membrane because they act as a barrier between the cellular environment and the extracellular material that surrounds the cells, selectively transferring the required molecules.

Which molecule could be best used as a supply of quick energy?
Carbohydrates
How do sheep store energy and matter?
Just like other mammals, sheep store energy in two main ways. These ways are glycogen (sugar) storage in the muscles, and lipid (fat) storage underneath the skin.
What do cells use for energy storage and insulation?
Cells use lipid molecules for energy storage as well as insulation and structuring. These molecules are mostly known in the vernacular as fats although they do encompass more than just traditional fat molecules.
Which food molecule monosaccharide polysaccharides lipid protein would you eat if you needed a quick boost of energy?
If I thought my blood sugar was low, or if my glucose meter said it was low, (I am a type II diabetic), I would eat something with glucose or take a glucose tablet or two or three, or eat something with sucrose (table sugar), or eat some fruit which has fructose (fruit sugar). If my blood sugar was 120 or higher, I would look for some caffeine. Coffee, black tea, cola, etc.
What molecules would you expect to have the most free energy per gram?
Apart from ATP, which enables our energy functions, the answer to your question is less absolute. Sugar/s would possibly hold the palm if only because there are so many of them overall. Or at least the carbohydrate and hydrocarbon group, simply because of their total mass. If you're thinking of the energy bound in the atomic structure itself, the answer is different again.
What major types of lipid are found in the plasma membranes?
Phospholipids, cholesterol, & glycolipids.
Why is the skin permeable to organic solvents?
Because they can dissolve the lipid bilayers of epidermal and dermal cell plasma membranes.
Is phospholipid one of the structured lipid found in cell membranes?
Yes,they are found in plasma membrane.They form the basic structure.
What is the structural model of the plasma membrane called?
The plasma membrane is the most thoroughly studied of all cell membranes, and it is largely through investigations of the plasma membrane that our current concepts of membrane structure have evolved. Theplasma membranes of mammalian red blood cells (erythrocytes) have been particularly useful as a model for studies of membrane structure. Mammalian red blood cells do not contain nuclei or internal membranes, so they represent a source from which pure plasma membranes can be easily isolated for biochemical analysis. Indeed, studies of the red blood cell plasma membrane provided the first evidence that biological membranes consist of lipid bilayers. In 1925, two Dutch scientists (E. Gorter and R. Grendel) extracted the membrane lipidsfrom a known number of red blood cells, corresponding to a known surface area of plasma membrane. They then determined the surface area occupied by a monolayer of the extracted lipid spread out at an air-water interface. The surface area of the lipid monolayer turned out to be twice that occupied by the erythrocyteplasma membranes, leading to the conclusion that the membranes consisted of lipid bilayers rather than monolayers
Which molecule has hydrophilic and hydrophobic properties and would be found in plasma membranes?
That would be phospholipids. They are a major component of the plasma membrane and contain hydrophilic, as well as, hydrophobic properties.
What are proteins embedded in the plasma membrane called?
They are called integral proteins
What is lipid rafts in plant membranes?
Lipid in membranes is phospholipid. It lays the foundation
What is found in some viruses and are external lipid membranes borrowed from the host cell.?
Lipid membrane called the Envelope
The components of membranes that account for most of their active functions are?
Diverse proteins embedded in the lipid bilayer or positioned at one of its surfaces carry out most of the membranes functions.
A lipid bilayer is characteristic of all membranes?
A lipid bilayer is characteristic of all biological membranes. Some membranes are double bilayers.
Surrounding each Cell in your body is a what and a what?
That is a bi-lipid Cell plasma membrane coated with a glyco-callyx Cell coat. Plant Cell plasma membranes are coated with a cellulosic Cell wall.
What does a lipid build in your body?
Lipids (fats, waxes, and oils that are essential for bodily functions) help to store energy, make up cellular plasma membranes as well as the membranes of organelles, and allow your body to absorb vitamins.
