Protein functions

Question 1

structure

Answer 1

Keratin, a tough structural protein, gives strength to the nails, hair, and skin surface.
deeper skin, bone, teeth, protein collagen.

Question 2

communication

Answer 2

hormones and other cell to cell signals are proteins, as are the receptors to which the signals molecules bind the receiving cell.

Question 3

membran transport

Answer 3

some proteins form channels in cell membranes (what and when)
protein turn nerve and muscle activity on and off.

Question 4

catalysis

Answer 4

most metabolic pathways of the body are controlled by enzymes, which are globular proteins that function as catalysts.

Question 5

Recognition and protection

Answer 5

neutralize organisms. Clotting proteins protect the body against blood loss.

Question 6

Movement

Answer 6

Movement is fundamental to all life. Protein are basis for all movement. some protein called molecular motors.

Question 7

cell adhesion

Answer 7

bind cell to each other enable sperm to fertilize eggs. enable immune cells to bind to enemy cancer cells, and keeps tissues form falling apart.

Question 8

Drastic conformational change that destroys protein function as occurs with extreme heat or PH often permanent like when an egg is cooked

Answer 8

Denaturation
