What must be true for a process where ΔG> 0?
- This process is spontaneous, meaning that it will not occur
- This process is spontaneous, meaning that it will occur
- This process is non-spontaneous, meaning that it will notoccur
- This process is non-spontaneous, meaning that it willoccur
Step by step
Solved in 4 steps
- According to Table 17.1, four reactions have positive ΔG values. How can this be explained?Why does the Krebs cycle operate only under aerobic conditionseven though it does not use molecular oxygen in any of its reactions?Regarding the reasoning for the Michaelis-Menten equation to be unsuitable for accurate analysis of experimental data, select all that apply: It is nonlinear It is only valid for reactions at equilibrium It is not valid under experimental conditions Extrapolation to Vm is inaccurate and therefore Km also cannot be accurately described
- Figure 6.8 Look at each of the processes shown, and decide if it is endergonic or exergonic. In each case, does enthalpy increase or decrease, and does entropy increase or decrease?Which steps in the Krebs Cycle do the following processes occur? a. Reaction utilizes FADb. Reaction generates NADHc. CO2 is removedd. Reaction forms a new C-C single bonde. Reaction breaks a C-C bondWhich catalytic mechanism contributes the most to rate acceleration?
- Why can’t an enzyme have a kcat/KM value greater than 109 M−1 ∙ s−1?Why does a pure noncompetitive inhibitor not changethe observed KM?Suggest an appropriate reason for the observation : “On increasing temperature of the reacting system by 10 degrees, the rate of reaction almost doubles or even some times becomes five folds.”
