The following data were obtained for the effect of temperature on the fermentative production of lactic acid by a strain of Lactobacillus delbrueckii.
From these data, calculate the value of the activation energy for this process.
Is the value of the activation energy typical of this sort of biological conversion?

Temperature (°C) Rate Constant (mol/ l-h)
40.4 0.0140
36.8 0.0112
33.1 0.0074
30 0.0051
25.1 0.0036

When in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? view available hint(s)when in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? active transportexocytosis
