4: Lipids (part 2: Phospholipids) Quizellenjmchenry2019-06-26T19:01:15-04:00 Please sign up for the course before taking this quiz. The “tail” of a phospholipid is hydrophilic.1 True False “Hydrophillic” means:1 "splits water" "loves water" "makes water" "hates water" Carbon atoms cannot form rings; only long hydrocarbon chains like those found in fatty acids.1 True False Phosphate is1 PO4 P02 P POH The part of the phospholipid that is hydrophobic is the1 phosphate. "head". "tail". A very basic phospholipid molecule is composed of1 a phosphate and two fatty acids. a phosphate and a fatty acid. a glycerol, 2 phosphates, and a fatty acid. a glycerol, a phosphate, and two fatty acids. EPA and DHA are “good” fatty acids.1 True False Water molecules are attracted to the phosphate head of the phospholipid.1 True False How many bonds does Phosphorus usually want to make?1 4 2 3 1 5 An electrically unbalanced molecule is called1 a proton. an acid. a hydroxyl. an ion. There are many different kinds of omega-3 fatty acids.1 True False Phosphate is negatively charged1 True False An unsaturated fatty acids has no double bonds in its hydrocarbon chain.1 True False EPA and DHA are1 phospholipids. phosphates. unsaturated fatty acids. saturated fatty acids. 3: Lipids and glycerol 5: Membranes (part 1) Back to: 4: Lipids (part 2: Phospholipids)
