The procedure for each lab is found on the page preceding the lab quiz in the Module.

Consider the C# method below for determining whether a given list of code words satisfies the prefix property. Note that there is a logical error in this method. Also note that the StartsWith method determines whether its parameter is a prefix of the invoking string; for example, “10110”.StartsWith(“101”) returns true, but “101”.StartsWith(“10110”)} returns false, and “11010”.StartsWith(“101”) returns false. public bool hasPrefixProperty(List code) {     for(int i = 0; i < code.Count; i++)     {         for(int j = 0; j < code.Count; j++)         {             if (code[i].StartsWith(code[j]))             {                 return true;             }         }     }     return false; } (a) (10 points) Explain and fix the logical error in the hasPrefixProperty method. In all subsequent questions, assume that this error has been fixed. (b) (20 points) Find a reasonable estimate for the best-case time-complexity of the StartsWith method of the string class called in the method above. You do not need to write code, but you can if it helps you explain your answer. (c) (10 points) What is the best-case scenario for the hasPrefixProperty method? (d) (10 points) Find a good estimate for the best-case time-complexity of the hasPrefixProperty method. (e) (15 points) Find a good upper bound for the worst-case time-complexity of the the StartsWith method. You do not need to write code, but you can if it helps you explain your answer. (f) (20 points) Find a good upper bound for the worst-case time-complexity of the the hasPrefixProperty method. You do not need to find the exact worst-case time-complexity here, but try not to give an unreasonably large upper bound. (g) (20 points) Suggest how the hasPrefixProperty method could be modified to improve its worst-case time-complexity.

Paragraph 3:  Muscle protein metabolism in the absorptive (fed) and fasted states.  Your response must describe the relative rates of protein synthesis and proteolysis during the fed and fasted states in terms of hormone signaling, specific membrane transporters, macronutrient availability, intracellular energy levels and master regulators of cellular metabolism.  

Match each of the non-protein nitrogen containing molecules below (left) with its description (right).

Select the true statements regarding protein synthesis and proteolysis (select ALL that apply).

Name a specific protein that performs each of the functions listed below. Carries oxygen through the blood: [blank1] Consumes oxygen during oxidative phosphorylation: [blank2] Accepts electrons from NADH in the ETC: [blank3] Accepts electrons from FADH2 in the ETC: [blank4] Regenerates the active form of glutathione: [blank5] Converts acetaldehyde to acetate: [blank6] Removes amide group from glutamine: [blank7] Catalyzes the following reaction [Ala + aKG Pyruvate + Glu]: [blank8] Marks proteins for degradation by proteasomes: [blank9] Incretin hormone that may suppress GLP1-induced vomiting: [blank10] Insulin sensitive glucose transporter: [blank11] Catalyzes the following reaction [Glu aKG + NH4]: [blank12] Senses intracellular ATP levels: [blank13] Structural protein of chylomicrons, VLDL & LDL (do not include #): [blank14] Stimulated by leucine, arginine and methionine: [blank15] Exchanges phosphates between ADP/ATP and creatine: [blank16]

Paragraph 2:  Hepatic de novo lipogenesis (DNL) during the fed state. First, describe the hormonal and biochemical conditions that stimulate hepatic DNL.  Then, describe the process of hepatic DNL in terms of incoming circulating fuels and the inputs and outputs of specific metabolic pathways, including TCA cycle metabolites.   

For each of the hormones below, indicate the organ from which it originates and whether the signal tends to increase or decrease appetite (in the blanks). GLP-1 Source organ: [blank1] Effect on appetite: [blank2] Ghrelin Source organ: [blank3] Effect on appetite: [blank4] Leptin Source organ: [blank5] Effect on appetite: [blank6] CCK Source organ: [blank7] Effect on appetite: [blank8] Cytokines Source organ: [blank9] Effect on appetite: [blank10]  

Part 1:  Mixed Questions (100 points) You must answer all questions. Read each question carefully and be mindful of word/sentence limits. 

Paragraph 2: Metabolic fates of amino acids in enterocytes.  Your response must state the 3 potential metabolic fates of amino acids in enterocytes and provide at least one molecular detail about each metabolic fate.
