What else can I help you with?
What can cross the phospholipid bilayer?
Small, non-polar molecules like oxygen and carbon dioxide can easily cross the phospholipid bilayer of a cell membrane. Larger or charged molecules typically need the help of transport proteins to pass through.
What can pass through the phospholipid bilayer?
Small, non-polar molecules like oxygen and carbon dioxide can pass through the phospholipid bilayer easily. Larger or charged molecules may need special transport proteins to help them cross.
Are fatty acid tails of a phospholipid molecules polar?
This is called the hydrophobic 'side' of the phospholipid molecule
The head of the phospholipid is?
The head of a phospholipid molecule is hydrophilic, meaning it interacts well with water. This phosphate-containing region has a charged or polar nature, allowing it to form hydrogen bonds with water molecules. This hydrophilic head faces outwards towards the water in cellular membranes.
Can polar molecules pass through the phospholipid bilayer?
Yes, polar molecules can pass through the phospholipid bilayer through facilitated diffusion or active transport.
What part of the phospholipid polar?
The head is polar
The phosphate groups are the polar part of the phospholipid because they are?
charged
What part of a phospholipid is non polar?
The head (or top) of a phospholipid is polar and the carbon chain tail is non-polar.
Is there a part of a phospholipid bilayer that is polar?
The tails, the part that doesn't contain phosphorus, are non polar and they are hydrophobic (afraid of water).
What part of phospholipid molecule would reject the polar molecule glucose?
The fatty acid tails of the phospholipid molecule would reject the polar molecule glucose, as the tails are nonpolar and hydrophobic in nature. Glucose is hydrophilic and would not be compatible with the hydrophobic environment created by the fatty acid tails.
What is polar of a phospholipid?
The head.
Is the polar head of a phospholipid made of molecules?
Phosphate molecules.
What part of a phospholipid is polar and non-polar?
The phospholipid bilayer in cell membranes is both polar and nonpolar. The heads, which face the outside and inside of the cell, are polar. Thus they form hydrogen bonds with the water outside of the cell and the cytoplasm inside the cell. They are called "hydrophilic," which means they love water. The tails are on the inside of the bilayer and are nonpolar. They are hydrophobic, which literally means they are scared of water.
What is non-polar trail and polar head?
Non-polar tail refers to the hydrophobic region of a phospholipid molecule, which repels water molecules. Polar head refers to the hydrophilic region of a phospholipid molecule, which is attracted to water molecules. Together, they form the phospholipid bilayer of cell membranes.
