Exam 3: Cells

The process by which cells specialize is called differentiation. 

Apoptosis begins with a cell receiving a signal to die.

Anderson's disease results in the failure to secrete large proteins called chylomicrons. Which organelle is most likely affected?

When you scrape your skin, white blood cells arrive to fight infection. To slow down near the site of the cut, they use selectin, which provides traction. Since selectin helps white blood cells bind to a surface, they are part of a protein group known as
