What is the role of proteins in the cell membrane

Question 1

How many proteins are found in the cell membrane

Answer 1

Thousands

Question 2

What role does proteins broadly play in the role of cell membranes

Answer 2

Proteins determine the function of the cell membrane.

Question 3

What role do carrier proteins play in the cell membrane?

Answer 3

Carrier proteins and channel proteins control the movement of water soluable ions and other molecules across the cell membrane

Question 4

How do proteins maintain an electrochemical gradient accross the cell membrane?

Answer 4

Proteins can also maintain an electrochemical gradient accross the cell membrane by maintaining different concentrations of ions on each side of the cell membrane

Question 5

How are proteins in involved in active transport accross the cell membrane

Answer 5

Other proteins are involved in active transport, where they use ATP to ferry ions accross the cell membrane, against a concentration gradient e.g. Sodium Potassium pump, where a specific protein uses energy from ATP in nerve impulse transmission.

Question 6

What role do receptor proteins play in the cell membrane

Answer 6

Receptor proteins recognise and bind with certain proteins outside the cell e.g. hormones and drugs.

Question 7

Which enzymes can be found in the cell membrane

Answer 7

Some enzymes can also be found in the cell membrane e.g. ATPase

Question 8

What is the role of glycoproteins in the cell membrane

Answer 8

Glycoproteins stick out of the cell membrane like antenaes and play an important role in helping cells to recognise each other and also cell signaliing. e.g. Antibodies

Question 9

What role do the proteins found in a cell membrane play
