BIOCHEM MODULE 9 QUIZ
1. Which of the following is not a major component of biological membranes?-
Answer Nucleic acids
2. An integral membrane protein is
Answer A protein whose amino acids are inserted into the membrane
3. Select all that apply.The fluid mosaic model of membrane dynamics states
that
Answer Lipids form a bilayer embedded with other molecules like proteins
Membranes are fluid meaning lipids, proteins, and other molecules can migrate within the structure
4. Lipids form from large polymers like proteins, nucleic acids
Answer False
5. Lipids do not form from large covalent polymers and instead associated with
other lipids through hydrophobic interactions to form membranes
1/5
, Answer True
6. Select all that apply. Fatty acids consist of
Answer a carboxylic acid a hydrocarbon tail
7. Which of the following statements is true
The fluidity of fatty acids decreases (they become less fluid/more solid) as...
Answer carbon tail length decreases
8. Which of the following is not a component of glycerophospholipids?
Answer Glucose
9. Which of the following glycerophospholipids has no net charge/is neutral at
pH 7.4?
Answer Phosphatidylethanolamine
10. Cardiolipin has which of the following "shapes" that function to help form
cristae in the inner mitochondrial membrane?
Answer Conical
11. Lipids with what charge tend to be more concentrated in the inner leaflet of
2/5
