Why do integral proteins stay in place in the phospholipid bilayer?
Wiki User
∙ 9y ago
Integral proteins are able to stay in the phospholipid bilayer because of the way they fold. Proteins have both hydrophic and hydrophilic regions that correspond to the regions of the phospholipid bilayer.

Can mitochondria produce protein?
The short answer: No.Mitochondria are the power-house of the cell. It is where the Electron Transport Chain takes place as well as the production site almost all of the ATP a cell produces. Proteins are produced by ribosomes of the rough endoplasmic reticulum.Okay... the answer above is only partially true. Mitochondria do, in fact, synthesize some of their own proteins, due to the fact that they contain their own DNA. However, the first respondent is correct that most of the proteins used in a cell are synthesized in the rough ER. Hope this helps.
Why is the cell membrane described as a phopholipids?
Cell membranes are made up of a phospholipid bilayer.. they have a hydrophilic (water loving) head and two hydrophobic (water fearing) tails. Phospholipids contain a phosphate group and a lipid group, that's why they are called that.
The lipids within the fluid mosaic of the plasma membranes are held in place by?
the phospholipids in the membrane are not actually held together by anything. They stay together because the heads are hydrophilic (water loving) and the tails are hydrophobic (they do not like water) so they line up in a bilayer with the tails on the inside and the heads on the outside and stay like this because of what each end of the phospholipid is attracted to
Why is water important in the cells?
most chemical reactions within cells could not take place without water
What gives the cell membrane support?
The plasma membrane is made up of Phospholipids and Proteins.Phospholipids have a hydrophilic "head" and a hydrophobic "tail". They form into two layers each with the "head" pointing outwards and the "tail" inwards. This means that the hydrophobic "tail" does not have contact with water.This enables;lipid-soluble molecules to move into and out of the cellprevent water-soluble molecules entering or leaving the cellthe membrane to be flexibleThe proteins are arranged more randomly and and are embedded in the phospholipid bilayer in two ways:Extrinsic proteins are on the surface and only partly embedded in it. They provide structural support or act as cell receptorsIntrinsic proteins occur across the plasma membrane and act as carriers to transport water-soluble molecules across the membrane. Some are enzymes.These proteins provide;supporta mechanism to transport water-soluble molecules across the membranea mechanism to allow active transport to take place by forming ion channels for sodium and potassium (to create the sodium-potassium pump)The last point about allowing active transport to take place is probably the most important.
What concentration does active transport take place in?
the phospholipid bilayer of a cell
What are the building blocks of phospholipids?
A phospholipid molecule is made up of fatty acids and a platform to which fatty acids are attached. A phospholipid molecule is also made up of a phosphate, and an alcohol that is attached to the phosphate.

What is integral setting?
An integral setting is a place that is important to a story. It is more than just mere background for a play.

What type of protein controls what goes in and out of cells?
Integral Membrane Proteins control the movement of substances into and out of the Cell (that cannot pass directly through the bi-lipid layer). These are proteins that span the width of the membrane [40 nanometers], and can be channels, pumps, gates of many descriptions, co-transporters, etc. As proteins go, these trans-membrane proteins have internal and external hydrophyllic lengths that have immensely important and varied bio-functions, and the trans-membrane segment is of course hydrophobic.
Which pronouns should be used in place of proteins it or they them?
The pronouns that take the place of the plural noun proteins are:they as the subject of a sentence or clausethem as the object of a verb or a preposition
What is the place where proteins are made?
Ribosomes
Where is the place where proteins are synthesized?
The ribosomes.
What do nucleus cytoplasm and cell membrane do to the cell?
Cell membrane controls the movement into or out of the cell. Nucleus controls all activities of the cell Cytoplasm a place for storing food and material,chemical reactions take place here.
Which place in India the diesel locomotives are manufactured?
Integral Coach factory Varanasi.
