c. on the surface of cell membrane
d. embedded in cell membrane

Which cellular organelle is responsible for packaging the proteins that the cell secretes?

Select one:
a. cytoskeleton
b. mitochondria
c. lysosome
d. Golgi apparatus

Fatty acids that are unsaturated have:

Select one:

Explanation / Answer

The primary elements forming biomolecules include

a. Carbon, Hydrogen and Oxygen

Where are nonpolar amino acids of a protein more likely to be found? Check all that apply

b. in the interior of soluble proteins
d. embedded in cell membrane

The non-polar amino acids are hydrophobic and are thus found in the interior of a soluble protein and embedded in cell membrane.

Which cellular organelle is responsible for packaging the proteins that the cell secretes?

d. Golgi apparatus

Golgi apparatus packages secretory proteins.

Fatty acids that are unsaturated have:

b. a double bond
