Question

Some infants cannot synthesize several of the traditionally nonessential amino acids. These amino acids must be obtained from the diet until the baby matures and are referred to as _________. complementary amino acids limiting amino acids conditionally essential amino acids nonessential amino acids In the context of protein synthesis, cell signaling is the process by which: amino acids are joined via peptide bonds. a protein's three-dimensional structure is altered the DNA strands in a cell combine to form chromosomes a cell is notified when to make a particular protein. The function of gastric lipase is to: convert the double bonds in fatty acids into single bonds. cleave fatty acids from glycerol molecules attract fatty acids to its hydrophilic head group. attach a phosphate group to the glycerol component of fatty acids. Which of the following is true of cholesterol? It interferes with calcium homeostasis in the body. It is highly miscible with water. It is used to synthesize bile acids. It inhibits the synthesis of reproductive hormones. Foods with a high proportion of __________ tend to be solid at room temperature. linoleic acid eicosapentaenoic acid monounsaturated fatty acids

Explanation / Answer

41. C. Conditionally essential amino acids

They are usually not required in the diet, infants do not synthesize some of these amino acids in sufficient amounts and therefore must be included in the diet.

42. D.cell is notified when to make a particular protein

Cell signalling for protein synthesis means a cue is sent to the cell to form mRNA gene of interest and is translated into protein.

43.b. Cleave fatty acids from glycerol molecules

Gastric lipase hydrolyzes triglycerides into fatty acids and monoglycerides

44. C. it is used to synthesize bile acids

Cholesterol is the important precursor of bile acids
