TEST BANK FOR CELLULAR AND MOLECULAR IMMUNOLOGY 9TH EDITION BY ABBAS Antibodies and Antigens Test Bank Matching Questions 1-5 Match each of the descriptions in questions 1-5 with the correct lettered antibody isotype (A-E). (Answers may be used more than once.) A. IgA B. IgD C. IgE D. IgG E. IgM 1. The secreted form of this isotype forms pentamers around a J chain ANS: E. IgM is secreted as a J chain–linked pentamer. 2. The most abundant Ig isotype in the blood ANS: D. The blood IgG concentrat...

Which steps involved in the contraction of a skeletal muscle require binding and/or hydrolysis of ATP? I Dissociation of myosin head from actin filament II Attachment of myosin head to actin filament III Conformational change that moves actin and myosin filaments relative to one another IV Binding of troponin to actin filament V Release of calcium from the sarcoplasmic reticulum VI Reuptake of calcium into the sarcoplasm A. I, II, and III only B. II, III, and IV only C. I, III, and ...

Amino Acid and Side Groups correct answers - Negative Side Groups = Acidic - Positive Side Groups = Basic Absolute Configuration correct answers refers the R/S naming convention. Some amino acids are R, and some are S. Relative Configuration correct answers - D/L naming convention. - All biologically produced amino acids are in the L configuration. Conformational stability correct answers - Temperature: Denatures second, third, and fourth tertiary - pH: Third and fourth; Destroys io...

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...

Three Ways of Doing Psychology1. Experimental 2. Teachers 3. Applied Critical Thinking1. What is the source? 2. Is the claim reasonable? 3. What is the evidence? 4. Could bias contaminate the conclusion? -emotional bias -conformational bias 5. Does the reasoning avoid common fallacies (common sense)? 6. Does the issue require multiple perspectives?

Which of the following differentiates the biochemical standard state from the standard state when discussing standard free energy changes? correct answers pH of 7 If a typical person hydrolyzes 100.0 mol of ATP per day, how much does this ATP weigh? (The molecular weight of ATP is 507 g/mol.) correct answers 50.7 kg A reaction is always spontaneous if correct answers the change in free energy, ΔG, is negative. Which of the following is an example of a heterotroph? correct answers yeast...

2 ways phosphate addition/removal causes conformational changes - Answer 1)Phosphorylation has a lot of negative charges that interfere with interactions between substrates --> forces protein into different conformations 2) phosphorylation of an enzyme can also alter substrate-binding affinity via electrostatic repulsion what happens to the GPCR and g-protein when a hormone reaches the GPCR receptor on cell membrane? - Answer hormone triggers a conformational change in receptor, which s...

Which of the following signaling types occurs during periods of development specifically for the secretion of growth factors? paracrine signaling Explain why a steroid hormone would require a carrier protein to transport it through the bloodstream. Steroid hormones are hydrophobic so they would need a carrier protein to carry it through the blood because carriers are hydrophilic Explain what a ligand is and give an example of one. A ligand is a molecule that has specificity for a given rece...
