An allosteric enzyme that is analogous to ATCase and follows the concerted mechanism (MWC model) has a T/R ratio of 300 in the absence of substrate. Suppose that a mutation reversed the ratio. How would this mutation affect the relationship between the rate of the reaction (V) and substrate concentration ([S])? Select all that apply. a. The enzyme would mostly be in the T form. b. The plot of V vs. [S]would be shaped like an S, sigmoidal. c. The enzyme would likely follow Michaelis-Menten kinetics. d. The enzyme would be more active. e. The plot of V vs. [S] would be shaped like a hyperbola.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.

answer : third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol

explanation :

let us write down the given equations

equation 1 :

equation 2 :

equation 3 :

let us use hess's law to find out which 2 equations can be added to get the third equation.

let us reverse equation 2 and multiply it by 2. the new equation that we get is,

equation 4 :

let us add equation 1 & 4

the above equation is similar to equation 3 but has different value for dhrxn.

therefore third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol
