G In the absence of allosteric effectors, the enzyme phosphofructokinase displays Michaelis–Menten kinetics (see Fig. 7.15). The v0/Vmax ratio is 0.90 when the concentration of the substrate, fructose-6-phosphate, is 0.10 mM. Calculate the KM for phosphofructokinase under these conditions (in units of mM).

The value of the Michaelis–Menten constant is 0.0111 mM.

Explanation:

Michaelis–Menten 's equation:

Where:

= rate of formation of products

[S] = Concatenation of substrate

=  Michaelis constant

 = Maximum rate achieved

= Catalytic rate of the system

= Initial concentration of enzyme

On substituting all the given values

We have :

[S] = 0.10 mM

The value of the Michaelis–Menten constant is 0.0111 mM.

i think it is true since you can test the answer and can use observations to complete it.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
