Question

Determine the structures of the molecules described in the following problems. Also note, in the combustion of N containing compounds, N₂(g) is made.

7. Recognizing that the binding of a particular protein to DNA is an exothermic reaction at 310K, with DH= -300 kJ/mol, How many protein molecules will need to bind (react) to change the temperature of an coli cell to 315K. (Assume that the cell is full of pure water, heat capacity is 1cal/g, density 1g/ml, and the volume of the cell is a femtoliter). Does this seem likely? (The most abundant proteins have about 70,000 copies per cell. )

Expert Solution

Step 1: Interpretation of problem sattement

Given Data:

Binding of a particular protein to DNA is an exothermic reaction at 310K with $increment H equals negative 300 space bevelled fraction numerator k J over denominator m o l end fraction$

Final temperature = 315 K

The most abundant proteins have about 70,000 copies per cell.

To determine:

Number of protein molecules will need to bind (react) to change the temperature of an coli cell to 315K
