Estimation of Vmax and Km by Inspection Although graphical methods are available for accurate determination of the Vmax and Km of an enzyme-catalyzed reaction (see Box 6-1), sometimes these quantities can be quickly estimated by inspecting values of V0 at increasing [S]. Estimate the Vmax and Km of the enzyme-catalyzed reaction for which the following data were obtained:

S [M] vo (μM/min)
2.5 x 10^-6 28
4.0 x10^-6 40
1.0 x 10^-5 70
2.0 x 10^-5 95
4.0 x 10^-5 112
1.0 x 10^-5 128
2.0 x 10^-3 139
1.0 x 10^-2 140

i think the miocene epoch spans the time from 23 million to 12 million years ago.

humans are now responsible for causing changes in the environment that hurt animals and plant species. we take up more space on earth for our homes and cities. we pollute habitats. human activity often changes or destroys the habitats that plants and animals need to survive.

the correct answer is b

after a the power stroke, adp is released, but the cross-bridge formed is still in place. atp then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site.
