6. Fatty acid synthase usually produces 16:0, but it sometimes can produce something longer or shorter. Let's assume it happens to produce 18:0. a) How many acetyl-CoA are required to make 18:07 (2 pts) b) How many NADPH are required to make 18:0? (2 pts) c) How many bicarbonate are required to make 18:07 (2 pts) d) In what cellular compartment does fatty acid biosynthesis take place? (2 pts) 7. A lipid bilayer consists solely of 1,2-distearoyl-sn-phosphatidylcholine. Assuming the bilayer...
LIPID AND MEMBRANE QUESTIONS 1. If an unsaturated fatty acid has 18 carbons, a double bond at position would be in notation - 2. The functional groups which hold fatty acid molecules and glycerol molecules together in triacylglecerol molecules are called: 3. If a triacylglycerol is heated in aqueous sodium hydroxide (lye) solution glycerol and the sodium salts of fatty acids are produced. This mixture of sodium salts of fatty acids is called in common terminology 4. Name the four...

(1 point) ATP synthase contains helical protein segments that span (or cross) the lipid bilayer. Proteins that span the bilayer like ATP synthase are called membrane proteins. 17. (1 point). The transport of a solutes across a membrane that utilizes energy is known as 18. (1 point) Plant starch is...
