In the fasted state, fatty acyl-CoA are transported across the mitochondrial membrane. The transport of fatty acids via carnitine palmitoyl transferase I (CPTI) can be directly inhibited by which of the following compounds? a. Malonyl CoA b. Carnitine c. Acetyl CoA d. Palmitate Malonyl CoA ...

Primary protein structure Linear sequence of amino acids in polypeptide chain. Written from amino (N) terminus to the carboxyl (C) terminus Secondary protein structure is made up of a-helix b-pleated sheets a-helix Carbonyl group of peptide bond forms a hydrogen bond with the amide nitrogen o...

Which of the following enzymes is likely to be active in both the fed and fasted states? (glutaminase, pyruvate kinase, hormone sensitive lipase, glycogen synthase) glutaminase (liver enzyme that is active in both fed/fasted; the rest are only active in one of the two states; in fed state, amino aci...

What is the role of adipose in metabolism? Storage of triacylglycerols as a source of energy that can be released as FFAs under fasted state conditions; other roles include body weight homeostasis, coagulation, immunity, vascular tone control, appetite regulation, glucose/lipid metabolism, reproduct...

Which of the following lipoproteins is responsible for carrying cholesterol from peripheral tissues (i.e skeletal muscle) back to the liver? HDL What is the primary role of LCAT (Lecithin-cholesterol acyltransferase)? To esterify cholesterol transported by HDL Which enzyme is responsible for t...

Which of the following best describes a protein domain? A section of a protein structure sufficient to perform a particular chemical or physical task If a mutation is made within the active site of an enzyme resulting in an increase in Km, which of the following will be true with respect to the e...

What enzyme is used by the gluconeogenic pathway but NOT in the glycolytic pathway? Phosphoenolpyruvate Carboxykinase PEPCK Newborn screening results show a biotinidase deficiency in a 2 day old infant. The deficiency impairs the infant's ability to reuse and recycle biotin. Due to the enzymatic...

Hemoglobin binds oxygen with a greater affinity in the: R state Hemoglobin bound to heme is termed a holoprotein. The heme or porphoryin ring is required for oxygen binding and it is termed a: prosthetic group Alpha helices and beta sheets are primarily stabilized by: H bonding Ligases are ...
