mm4. match the phospholipid to its best description.
type of phospholipid without a glycerol backbone. 1. phosphatidylcholine
the most common phospholipid 2. galactocerebroside
fungis type of steroid nucleus lipid 3. ergosterol
question 22 (1 point)
pes8. list the term that describes a loose, water soluble glycocalyx. (two words)

Explanation:

1. Phospholipids are important cell - membrane components. Phosphatidylcholine is a common phospholipid. Galactocerebroside is a glycolipid, not a phospholipid without a glycerol backbone. Ergosterol is a sterol in fungi, not a phospholipid. The phospholipid without a glycerol backbone is sphingomyelin (not in the given options). The most common phospholipid is phosphatidylcholine. Ergosterol is the fungal sterol.
2. A loose, water - soluble glycocalyx is called a slime layer.

Answer:

Question 21:

• Type of phospholipid without a glycerol backbone: (No correct option given)
• The most common phospholipid: 1. Phosphatidylcholine
• Fungi's type of steroid nucleus lipid: 3. Ergosterol

Question 22: slime layer
