A) is the site of protein synthesis
B) contains the genetic code
C) transforms cellular energy
D) initiates aerobic metabolism
2. Although energy is not made in mitochondria, they are known as the power plants of the cell because
they:

specific membrane functions are carried out by:
A) bound and transmembrane proteins.
B) complex, long carbohydrate chains.
C) surface antigens and hormone receptors.
D) a gating system of selective ion channels.
