What else can I help you with?
Can nonpolar molecules cross the lipid bilayer?
Yes, nonpolar molecules can cross the lipid bilayer because the lipid bilayer is made up of nonpolar molecules itself, allowing nonpolar molecules to pass through easily.
Do lipid soluble molecules diffuse into a cell more rapidly than water soluble molecules?
Yes, lipid soluble molecules diffuse into a cell more rapidly than water soluble molecules. This is because the cell membrane is primarily made up of lipids, so lipid soluble molecules can easily pass through the lipid bilayer, while water soluble molecules need specific channels or transporters to facilitate their entry into the cell.
Is protein a lipid?
No, protein is not a lipid. Lipids are a class of molecules that include fats, oils, and cholesterol, while proteins are a class of molecules made up of amino acids that play a variety of roles in the body.
Why is a lipid bilayer incellmembrane considered as a barrier to the diffusion of polar molecules?
Polar molecules are hydrophilic in nature. They tend to repel from the lipid content and would easily adhere or mix with the water molecules. A lipid bi-layer consists of lipids and so it would not allow the polar molecules to pass through.
Why can molecules that are fat-soluble permeate across a cell membrane?
Cell membranes are composed of a lipid bilayer. Cellular fluid (cytosol) and the cell's organelles are contained by the cell's membrane, which is composed of a lipid bilayer. Lipids are a type of fat. Because a cell's membrane is composed of fat, only fat-soluble molecules are able to dissolve through the membrane into the cytosol.
What is lipid bilayer?
thin membrane made of two layers of lipid molecules.
Can nonpolar molecules cross the lipid bilayer?
Yes, nonpolar molecules can cross the lipid bilayer because the lipid bilayer is made up of nonpolar molecules itself, allowing nonpolar molecules to pass through easily.
What is the cell made of?
The cell membrane is made of carbohydrate, lipid, and protein molecules.
Are triglycerides lipids?
Triglycerides are lipids in a way. A lipid is a broad category of macromolecules. In this category is fatty acids. One triglyceride consists of a glycerol back bone and 3 fatty acids. Doing this is a way for your body to store fatty acids. So Yes, in a way a triglyceride is a lipid, but don't forget that the category "Lipid" is made up of other molecules as well.
What are Fat or lipid molecules mostly made of?
Carbon hydrogen oxygen
What kind of molecules are wax and testosterone?
hydrophobic molecules. Testosterone is a hormone made of sterol.
Is lipase a lipid?
No, lipase is not a lipid. Lipase is an enzyme that breaks down lipids (fats) into smaller molecules such as fatty acids and glycerol. Lipids are a type of biological molecule that includes fats, oils, and other substances that are insoluble in water. Thanks
Is lipid made from organic molecules?
It's based on carbon, so yep.
Do lipid soluble molecules diffuse into a cell more rapidly than water soluble molecules?
Yes, lipid soluble molecules diffuse into a cell more rapidly than water soluble molecules. This is because the cell membrane is primarily made up of lipids, so lipid soluble molecules can easily pass through the lipid bilayer, while water soluble molecules need specific channels or transporters to facilitate their entry into the cell.
Is protein a lipid?
No, protein is not a lipid. Lipids are a class of molecules that include fats, oils, and cholesterol, while proteins are a class of molecules made up of amino acids that play a variety of roles in the body.
Why can only molecules that are fat soluable permate a cell membrane?
The cell wall itself is made of lipid. To be more precise, the cell membrane is made of a bilayer of phospholipids. The hydrophobic fatty acid tails prevent water-soluble molecules passing through, but allow the transport of lipid-soluble molecules.
Why is a lipid bilayer incellmembrane considered as a barrier to the diffusion of polar molecules?
Polar molecules are hydrophilic in nature. They tend to repel from the lipid content and would easily adhere or mix with the water molecules. A lipid bi-layer consists of lipids and so it would not allow the polar molecules to pass through.
