The three Complement pathways utilize different means of achieving the same three goals: opsonization, cytolysis and inflammation. It is how the pathways are activated that differs between each of them. Which of the following statements is NOT true? The Classical Complement Cascade was discovered first and is usually triggered by antibodies that are bound to an invading agent.The Alternative Pathway to complement activation was discovered secondarily and requires alternative proteins to activate the cascade.The Lectin Pathway is not activated by antibodies but by a blood protein (mannose-binding lectin) that combines with certain sugars on the microbe’s surface.The entire Complement cascade is triggered by the C3 protein, named for the order in which it was discovered, not its position in the cascade.
In considering the three criteria for causation, which of the following questions will Dr. Farah's study NOT be able to address? Is there covariance? Are there third variables that could explain the relationship? Do the rules make intuitive sense? Is there temporal precedence?
3. A soluble complex MX+ dissociates according to the reaction: MX+ \(\rightleftharpoons\) M? + X • The metal ion, M?, and the ligand, X, do not absorb at 560 nm but the complex MX+ does. • A solution that was known to be 2.10 \(\times\) 10? M in MX+ had an absorbance of 0.481 at 560 nm in a 1-cm cell. • Another solution was prepared by taking 10 ml of 1.28 \(\times\) 10³ M M? and 10 ml of 1.31 \(\times\) 10³ M X and diluting to exactly 100 ml. If the absorbance of this solution was 0.278, calculate the formation constant for the complex MX+. (10 marks)
