25 Blood coagulation involves: A) a kinase cascade. B) zymogen activation. C) serine proteases. D) both...
Secondary hemostasis in vivo (inside the body) involves: A. Platelets B. Coagulation cascade C. Fibrin formation D. All of the above
task
Another factor that participates in the coagulation cascade is
factor XIa. Like other proteases in the blood, factor XIa is
regulated by an inhibitor, antithrombin III, which is a member of
the serine protease inhibitor family (serpins).
1. Why does the body need an inhibitor like antithrombin?
Heparin is a highly sulfated glycosaminoglycan polymer that
affects the activity of serpins like antithrombin III. It is used
in medicine to treat inter alia thrombosis (formation of blood
clots in the...
1) (10 pts) Serine proteases are enzymes that cleave peptide bonds in proteins. Explain using words (drawings OR both) why serine proteases cleave either before or after different amino acid residues. Talk about at least two of the following proteases: Chymotrypsin, Trypsin, or Elastase. mod 2) (10pts) Below is a hypothetical peptide sequence. Give the peptide fragments that will occur by enzymatic degradation using Trypsin and Chymotrypsin DARSKWKSENLIRTY 3) (10 pts) All superfamilies of serine proteases use the catalytic triad...
You may choose more than one answer. Activation of protein kinase C (PKC) involves: DAG associates with the membrane and allosterically binds PKC Calcium decreases the affinity of PKC for negatively charged lipids Regulated by phosphorylation at specfic sites Removal of psuedosubstrate from kinase core C2 domain binding of phosphatidylserine (to be membrane attached)
Which is a similarity between hemostasis and coagulation? a) Both prevent hemorrhage. b) Both involve a decreased diameter of blood vessels. c) Both are defined as the formation of a clot. d) Both form a platelet plug.
Which of the following statements concerning signal transduction by the insulin receptor is NOT correct? A. The insulin receptor substrate protein IRS-1 in its phosphorylated form activates other proteins. B. The pathway for insulin-stimulated transcription of specific genes involves the protein Ras. C. The insulin receptor phosphorylates itself in the activation process. D. Insulin stimulation of the insulin receptor initiates a cascade of events causing activation of glycogen synthase. E. The receptor protein kinase activity is specific for serine residues...
DNA excision repair A. involves only two distinct steps. B. requires visible light for activation. C. replaces both strands of a segment of DNA. D. is deficient in some human hereditary diseases. E. is blocked by allopurinol.
90. This condition is also known as hump back. A. lordosis B. kyphosis C. scoliosis D. spina bifida E. hemiated disk 91. Fibrinolysis is responsible for A. activation of the intrinsic pathway of coagulation. B. activation of the extrinsic pathway of coagulation. C. clot retraction. D. clot dissolution. E. clot consolidation. 92. Unlike an exocrine gland, an endocrine gland A. is a secretory organ. B. sheds cells with its secretions. C. has no ducts. D. contains goblet cells. E. secretes...
e HPA axis involves the initial activation of the: a. hypothalamus b. hindbrain 18. Th c.hippocampus d. heart 19. Each of the following is the result of activation of the sympathetic nervous system in response to a stressor EXCEPT: a. heart rate increases b. pupils dilate c. breathing becomes more rapid d. muscle tension decreases ??20. In humans, the alarm stage of the general adaptation syndrome involves: a. the inhibition of the hypothalamic-pituitary-adrenal system b. the production of cortisol, which...
Hemolytic disease of the newborn A) involves ABO blood groups. B) involves IgM crossing the placenta. C) causes the liver to break down. D) results in bilirubin deposition in the brain. E) is difficult to prevent.
