An interesting enzyme, whose molecular weight is 56,000 g/mol, is used in catalytic amounts to cleave a membrane protein, whose
molecular weight is 65,000 g/mol, into two fragments having molecular weights of 43,000 and 22,000 g/mol. Gel chromatography is used to assess the extent of reaction at various times. Three major fractions of proteins are eluted at each time. What are they and in what order are they eluted

Answer:
Q = 16163.88 Joules
Explanation:
Given the following data;
Initial temperature, T1 = -25°C
Final temperature, T2 = 150°C
Mass = 45.5 g
Specific heat capacity of ice = 2.03 J/g°C
To find the quantity of heat required;
Heat capacity is given by the formula;
Where;
Q represents the heat capacity or quantity of heat.
m represents the mass of an object.
c represents the specific heat capacity of water.
dt represents the change in temperature.
dt = T2 - T1
dt = 150 - (-25)
dt = 150 + 25
dt = 175°C
Substituting into the formula, we have;
Q = 16163.88 Joules
