5. A protein unfolds according to the scheme N
properties (property 1 and 2) are measured at three points in the unfolding
reaction where the true values of fp are 0.2, 0.5 and 0.8. The corresponding
values of K = fx/ fp are 1.0, 0.4 and 0.125. For property 1, d₁ = 0.1; for property
2, d₁ = 0.2.
(a) Write an equation that can be used to calculate fapp.
(b) Calculate fapp using d₁ = 0.1 (property 1) and fapp using d₁ = 0.2
(property 2).
(c) The error in measurement of each physical property is 5 %. Can
you detect the presence of the intermediate by measuring the
physical properties? Explain your answer

Q-8a. Choose from the terms below to Fill-in the Blanks. [All terms are used. Some terms are used more than once] Rab, SNARE, v- SNARE, t-SNARE, Tethering a. Identification of a vesicle to be docked depends on a diverse family of monomeric GTPases called proteins. First, a filamentous protein on a target membrane binds to a protein on the surface of a vesicle. This interaction allows the vesicle to dock on its particular target membrane. A on the vesicle then binds to a complementary_ on the target membrane. Whereas and proteins provide the initial recognition between a vesicle and its target membrane, complementary appropriate target membranes. Together, the proteins ensure that transport vesicles dock at their proteins catalyze the final fusion of the two membranes by squeezing out water making fusion more energetically favorable. b.
