Question 1Predicting Secondary Structure Which of the following peptides is more likely to take up an -helical structure, and why? (a) LKAENDEAARAMSEA (b) CRAGGFPWDQPGTSN
QUESTION NO. 1L-Carnitine is synthesized primarily in the liver but also in the kidneys and then transported to other tissues. It is most concentrated in tissues that use fatty acids as their primary fuel, such as skeletal and cardiac muscle. In this regard, L-carnitine plays an important role in energy production by conjugating to fatty acids for transport from the cytosol into the mitochondria. L-carnitine shuttle is an example of A. ion driven active transport B. facilitated diffusion C. simple diffusion D. ATP driven active transportE. symport F. antiportQUESTION NO.2 Statements: (1) Glucose is both a hexose and a aldose. (2) There can never be more than three enantiomers for a molecule. (3) All common disaccharides have beta-one-four linkages. Which statements are true?
Question 1: The overall process enabled by the glyoxylate cycle is: (2acetyl-CoA) + (NAD+) + (2H2O) → (succinate) + (2CoA) + (NADH) + (2H+) Dissect this process further by writing down all of the reactions that are actually involved in making one succinate from two acetyl-CoA units. Show chemical structure for all intermediates.
Question 9 Why does acetyl Co-A occupy a central role in cellular metabolism? Question 9 options: Acetyl Co-A is essential to the catabolic process that includes triglyceride synthesis Only amino acids and glucose can be converted to acetyl Co-A since glucose cannot be derived from fatty acids Amino acids, fatty acids and glucose can all be converted to acetyl Co-A Acetyl Co-A is essential to the anabolic process that includes the citric acid cycl
Question 11. // Hint: Isoelectric focusing separates proteins based on their pI values, and can separate proteins that only differ by a net charge of ±1.±1. Recall that an amino acid residue with a negatively charged R group has a relatively low isoelectric point (pI) where it has zero net charge. Likewise, an amino acid residue with a positively charged R group has a relatively high isoelectric point (pI) where it has zero net charge. Order from Low pH to High pH
Question 2 : Which of the following sentences are INCORRECT? Prostaglandins, a family of lipid compounds derived enzymatically from essential fatty acids, act as vasodilators and inhibit the aggregation of blood platelets. The patient presented to the clinic with a 2-day history of fever (temperature up to 40°C), nausea, and emesis, The specific activity of chitinase was significantly lower than that of lipase, It is important to compliment opioid therapy with simple analgesics and anesthesia.
