What else can I help you with?
The phospholipid sea in which embedded substances float?
The phospholipid bilayer of the cell membrane, also known as the lipid bilayer, is where embedded substances like proteins and cholesterol float. This fluid mosaic model allows for dynamic movement of molecules within the membrane. The hydrophobic tails of the phospholipids form a barrier that helps control the passage of substances in and out of the cell.
Do glycerol heads have a positive or negative charge?
The glycerol heads in phospholipids are neutral and do not have a positive or negative charge. The charge on a phospholipid molecule is predominantly determined by the phosphate group located on the glycerol backbone.
What is the verb of the word move?
Move is already in verb form.There is also moves and moved.Some examples are:"I will move the wardrobe"."He moves the wardrobe"."He moved the wardrobe".
What the adjective of move?
You could do 'quickly moving', 'slowly moving'.. Etc. If you're only using move not moving, the same would still apply. You could do fast move, slow move, bad move, good move and many more-- whichever fits the situation the best.
What two thing move swiftly?
A cheetah can move swiftly on land and a peregrine falcon can move swiftly in the air.
Can everything move in or out of the cell?
No, the cell membrane, which is a phospholipid bilayer of embedded proteins, regulates what enters and leaves the cell.
What particles move through cell membrane between phospholipid molecules What transport?
Osmosis, Passive Transport, and Active Transport
Does osmosis move phospholipid bilayer or protein channel?
Osmosis moves water molecules across the phospholipid bilayer of a cell membrane. Protein channels help facilitate the movement of water and other molecules by providing a pathway through the membrane.
Is cholesterol a phospholipid?
No it is in fact not a phospholipid just a lipid. A phospholipid needs a phosphate group and cholesterols molecular formula is C-27 H-46 O and with no Phosphate it can not be a phospholipid.
What molecule could move through a phospholipid membrane with the least difficulty?
A small, non-polar molecule like oxygen or carbon dioxide would move through a phospholipid membrane with the least difficulty, as they can easily pass through the hydrophobic interior of the membrane without the need for a specific transport protein.
Does plasma membrane have phospholipid layer?
A phospholipid bi-layer.
If you label with 14C radioactive a phospholipid part of plasma membrane and follow this lipid over a period of time what would you see this phospholipid doing?
You would observe the radioactive phospholipid moving within the plasma membrane as the cell grows and divides. This movement is due to the dynamic nature of the lipid bilayer, where phospholipids can laterally diffuse and move within the membrane. Over time, you may also witness the turnover of the labeled phospholipid as it gets degraded and replaced with newly synthesized phospholipids.
What general type of molecules is a phospholipid?
The head and tail is a phospholipid molecule
Because the phospholipid molecules and some proteins are free to move the plasma membrane is said to be?
Because the phospholipid molecules and some proteins are free to move, the plasma membrane is said to be fluid, allowing for flexibility and dynamic changes in its structure. This fluidity is essential for various cellular processes such as cell communication and transport of molecules across the membrane.
What process transports particles that move through cell membrane between phospholipid molecules?
The process that transports particles through the cell membrane between phospholipid molecules is called passive diffusion. In passive diffusion, particles move from an area of higher concentration to an area of lower concentration without the need for energy input.
He fatty acids in the tail of a phospholipid molecule are?
This is called the hydrophobic 'side' of the phospholipid molecule
Is testosterone a phospholipid?
No... It is a lipid because it is a hormone and hormones are lipids, but it is not a phospholipid.
