QUESTION 5 [20]Describe and compare the metabolism of carbohydrates, lipids and proteins and in your answer, explain the role of ATP. Also discuss the differences between anabolic and catabolic pathways, the regulation of metabolic pathways and the differences in metabolism between the well-fed and 1.1 Describe the structural characteristics that are common to all the amino acids that are found in mammalian proteins and draw the structure of the tripeptide Tyr-Thr-Trp in the ionic form that predominates at pH 7. Show all atoms (including hydrogens) as well as any charges as necessary. Explain the general features of amino acid side chains and the importance of associated non-covalent interactions. (1fasting state.
Question 9 Imagine you have a mixture of 2 proteins. Protein A is 3x the mass of protein B. Both have net negative charges, but protein B has 3x more negative charges than protein A. If you load the mixture onto an electrophoresis gel and apply an electric field, which will move faster/slower through the gel? Explain your reasoning.
Question:- The enzyme aromatase is found in the cytoplasm of some cells and converts testosterone to estrogen. You decide to test aromatase from a particular cell, and oops, your lab partner admits he drastically increased the pH in all the test tubes. Which of the following is a likely result? a. The enzyme will be denatured and the substrate will not bind to the active site. b. The enzyme will convert testosterone to estrogen at a faster rate. c. The mistake will have no effect on the experiment, because enzymes are not sensitive to pH. d. The free energy will be lowered and the reaction will not proceed spontaneously.
Question 1. A "relaxed" animal conserves its glycogen and oxygen, and in this way lactic acid can be produced enzymatically, which naturally softens the meat, favors its softening and makes it easier for other enzymes to synthesize compounds responsible for aroma and flavor True or false Question 2: For the Maillard reaction to occur, _____ a and ______ a group part of an amino acid or protein . a. reducing sugar, amino b. amino sugar, hydroxyl c. Ketosis, Ketone, D. aldose, phosphate
Which statement is true regarding denaturation process? Question 21 options: Protein experiences hydrolysis as it denatures and alters its structure. Denaturation is the process of altering the shape of a protein that involves breaking the amide bonds. Denaturation is the process of altering the shape of a protein without breaking the amide bonds. As protein denatures, new peptide bonds form with the added amino acids.
Question 22: which of the following secondary structures would you expect to find on the surface of a globular protein? Alpha helix Beta sheet Loops between two alpha-helices None of the above because water would disrupt the hydrogen bonding that stabilizes these structures A,B and C as long as the polar and charged amino acid side chains face the surface of the protein.

Question for protein crystallography- 1. While performing a routine protein crystallization screening, you observe that one of your well drops has doubled in size compared to the remaining wells. Note: the drop in question was set up by taking 1 µL of the protein solution (10 mg/mL LDH in 20 mM TRIS pH 7.5, 0.5 M NaCl and 10% PEG 4000K) and adding it to 1 µL of the crystallization solution (10% PEG 4000K, 50 mM NaCl and 20 mM TRIS pH 8.0). Why did this drop grow larger in size compared to when you initially set it up?
