- 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 22 When the final product of a series of enzymatically-catalyzed reactions binds to the first enzyme in the pathway to limit its production, it generally uses ___ because the structure of this final product is generally not similar to that of any of the enzyme's normal substrates. Allosteric activation Zymogen activation Covalent modification Competitive inhibition Allosteric inhibitionQUESTION NO. 1Targeting a protein to be degraded within proteasomes usually requires ubiquitin. In the function of ubiquitin all of the following are true except: A. ATP is required for activation of ubiquicin. B. a peptide bond forms between the carboxyl terminal of ubiquitin and an ε-amino group of a lysine . C. linkage of a protein to ubiquitin does not always mark it for degradation.

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 pHquestion 24 DNA is a hereditary molecular that is composed of A Deoxyribose,phosphate, and nitrogen bases B Deoxyribose,a pentose, and nucleic acids C Sugar,proteins and thymine D Adenine, phosphate, and ribose
- QUESTION NO. 1 Cystic fibrosis is a frequent generic disease of Caucasians. The CF gene codes for a protein called the cystic fibrosis transmembrane conductance regulator (CFTR) which functions as a cAMP-regulated chloride channel. The protein has two membrane-spanning domains, two domains that interact with ATP, and one regulatory domain. The most common defect is in the gene for one of the ATP binding domains. The result is a protein that does not fold correctly in the endoplasmic reticulum, is not properly glycosylated, and is nor transported to the cell surface. Rather, it is degraded in the cytosol within proteasomes. Drugs that foster chaperone interaction with the mutant protein are a potential therapeutic approach. Chaperones A. are always required to direct the folding of proteins. B. when bound to protein increase the rate of protein degradation. C. usually bind to strongly hydrophilic regions of unfolded proteins. D. sometimes maintain proteins in an…Question 10 (2 points) A protein heterodimer would be considered an example of: -primary structure -secondary structure -tertiary structure -quaternary structure -atomic structureText:QUESTION 16 Protein maturation in the ER includes.

- Question 1: When the CAC is run in reverse by microorganisms that use it to fix carbon, the citrate synthase reaction is different and is catalyzed by an enzyme called ATP-citrate lyase. Write the reaction catalyzed by ATP-citrate lyase, then briefly (in one sentence) explain why the use of different chemistry (different from the ‘normal’ direction) makes sense here.Question:- 33) Glucose-6-phosphate has different pathways that it can enter in the liver during the fed state. All of the following are possible except OA.) it is oxidized to acetyl CoA for fatty acid biosynthesis O B). it can enter the pathway for glycogen biosynthesis O c.) it is a substrate for glucose-6-phosphatase OD. )it is oxidized in glycolysis to provide energy for the bodyQuestion 1: ATP synthases contains 3 copies of each of the large subunits (called α and β in the E. coli enzyme). The number of c subunits can vary among different ATP synthases, ranging from 8 to 17. Part a: Briefly explain how this variation in the number of c subunits would affect the energetics of ATP synthesis. For a fixed value of the protonmotive force, how much energy can the gradient provide to drive one revolution of the ATP synthase, in a synthase with 8 c- subunits versus a synthase with 17 c-subunits?
