membrane and phospholipids

Question 1

what are the six components of the phospholipid bilayer?

Answer 1

• Phospholipids
• Extrinsic proteins
• Intrinsic proteins
• Glycolipids
• Glyco proteins
• Cholesterol

Question 2

What is the function of the plasma membrane?

Answer 2

To regulate what enters an access the cell and as a barrier between the internal contents and the external environment. It’s also a site to sell communication and signalling

Question 3

what are the components of a phospholipid and the characteristics?

Answer 3

-The head of a phospholipid is made of glycerol and phosphate molecules and is hydrophilic
- tale of a phospholipid is made out of fatty acids and is hydrophobic

Question 4

What is the function of a phospholipid?

Answer 4

To regulate our end is an exits, the cell and make the membrane flexible

Question 5

what is the function of extrinsic proteins?

Answer 5

help maintain cytoskeleton and act as receptors

Question 6

what is the function of intrinsic proteins?

Answer 6

Act as a channel for larger, insoluble, molecules and water soluble molecules to enter the cell

Question 7

What’s the function of glycolipids?

Answer 7

Cell signalling

Question 8

What is the function of glycoproteins?

Answer 8

Enable cell adhesion with other proteins to help form tissues. They also pass signals through the plasma membrane.

Question 9

What is the function of cholesterol?

Answer 9

Adds mechanical strength and flexibility

Question 10
