DNA D. lipid - CORRECT ANSWER-B. Protein 2. Egg whites consist primarily of water and the protein albumin. When you fry an egg, why does the egg white turn from clear to white? A. The protein bec...

ligand - Is the word for a drug or a bio molecule a molecule that is reversibly bound to a protein, examples oxygen, endogenous neurotransmitters, hormones, drug molecules Binding site - A discrete portion of the protein that is complementary to the ligand in: - Shape and size - Charge distribution - Hydrophobic and hydrophilic regions ***Is involved in specific interaction, certain structural features must be present on the ligand for binding Induced fit - A complementary conformationa...

AP Biology- Biochemistry Latest Update 100% Correct adhesion attraction between different kinds of molecules alkaline synonym for basic allosteric inhibition two active sites, one for a substrate and one for an inhibitor alpha helix secondary structure form of a protein; human hair (keratin) amine nitrogen bonded to two hydrogens and to the carbon skeleton amylopectin more complex storage polysaccharide form of starch amylose simplest storage polysaccharide form of starch...

BRS: BIOCHEM NITROGEN METABOLISM ?S EXAM QUESTIONS AND ANSWERS WITH COMPLETE SOLUTIONS 1. The answer is A. Trypsin cleaves and thus activates the pancreatic zymogens, converting chymotrypsinogen to the active form, chymotrypsin, and the procarboxypeptidases to the active carboxypeptidases. If trypsin were inactive, the other proteases could not be activated because enteropeptidase is specific for trypsinogen. Pepsin is found in the stomach, whereas aminopeptidases are intestinal enzymes found o...

BI234 CH - MICROBIAL METABOLISM EXAM QUESTIONS AND ANSWERS WITH COMPLETE SOLUTIONS What role do enzymes play in metabolic pathways? Enzymes control the chemical reactions in metabolic pathways. They are necessary for metabolism to occur. How is the action of a competitive inhibitor different from that of an allosteric inhibitor? -Competitive inhibitors have a shape that is similar to the substrate of the enzyme and bind to the active site of the enzyme - these inhibitors compete for the ac...

Metabolic Biochemistry Exam 1 UPDATED ACTUAL Exam Questions and CORRECT Answers How do allosteric effectors affect enzyme structure and function? - CORRECT ANSWER- "from a distance" allosteric inhibitors can either activate or deactivate an enzyme. Example of allosteric inhibitor - CORRECT ANSWER- ATP = allosteric I for ATCase

Biochemistry Test 1 Questions and Answers Graded A+ What is the role of allosteric sites in enzyme regulation? Allosteric sites are regions where molecules can bind and influence enzyme activity by changing its shape. How do competitive inhibitors affect enzyme function? Competitive inhibitors compete with substrates for binding at the active site, reducing enzyme activity. What determines the tertiary structure of a protein? The tertiary structure is determined by interactio...

UNE Medical Biochemistry Midterm Review Already Graded A A family presents for genetic counseling. The couple has two female children who are alive and well; however, their infant son recently died in the nursery with severe hemolysis (lysis of red blood cells) and jaundice. The wife recalls she lost a brother in infancy with severe hemolysis, induced after a viral infection. The physician suspects a glucose-6-phosphate dehydrogenase deficiency, this would result in a deficiency in which of the...

Biochemistry Questions and Answers with Verified Solutions How do cofactors assist enzymes in catalysis? Cofactors are non-protein molecules that bind to the enzyme and assist in catalyzing reactions, often by stabilizing the transition state. What is the function of the electron transport chain in cellular respiration? The electron transport chain transfers electrons through a series of protein complexes, creating a proton gradient that drives the synthesis of ATP. What are the buildi...
