825.5mL
To find this, use the equation
= 
Make sure to convert all temperatures in Celsius to Kelvin by adding 273. Once you do that, multiply and divide accordingly to get the final answer of 825.5mL
Hope this helps!
I think it was D. Hopefully I’m right
The Km is the MIchealis-Menten constant and this represents the affinity of the enzyme to its substrate. The higher the value for Km, the higher is the affinity of the enzyme to a substrate and the greater is the rate of reaction. Hexokinase IV has a higher Km than other hexokinases because it has a higher affinity to hexose substrates.
