UNIT 1 UNE CHEM 1005 EXAM QUESTIONS AND ANSWERS Hemoglobin binds oxygen with a greater affinity in the: R state Hemoglobin bound to heme is termed a holoprotein. The heme or porphoryin ring is required for oxygen binding and it is termed a: prosthetic group Alpha helices and beta sheets are primarily stabilized by: H bonding Ligases are a class of enzymes characterized by their ability to: synthesize bonds between carbon atoms and an additional atom that is involved in the cleavage of ...

Biochemistry II Exam 1 Questions And Answers A+ Review Solution Homeostasis is the maintenance of a dynamic(not static) steady state in an organism through careful control of biochemical processes. Example is regulation of glycolysis and gluconeogenesis(blood glucose high we want glycolysis to occur and low blood glucose levels we want gluconeogenesis to occur) - ANSWER-Define homeostasis and provide an example of a cellular process that helps maintain homeostasis. oxidative processe...

How do most enzymes reduce the activation energy needed to move a reaction forward? Providing an active site most complementary the transition state We have an expert-written solution to this problem! An enzyme has a mutation within the substrate binding of the coenzyme needed for covalent catalysis. Which of the following is likely to result as a consequence of this mutation? The enzyme will not be able to form the transition state complex Hemoglobin has the ability to display ...

A 19-year-old boy is diagnosed with Creutzfeldt-Jakob disease which is caused by the introduction of an amyloid fold in the disease-causing protein. The introduction of this fold causes the protein to transition from a primarily alpha helical structure to an aggregate of mostly beta sheets. This change in protein structure (leading to disease) is best attributed to changes in which of the following? folding of the secondary structures Which of the following is the best description of pri...
