Homework Answers
First need to calculate the ΔH and is a product of heat capacity (Cp) and temperature change (ΔT)
ΔH=418x1.48=618.64 J/K
Now estimate the number of moles of ATP mixed with ATPase
You have taken One hundred milliliters of 0.200 M ATP, so moles= (100mlx1L/1000ml)x0.2 mol/L=0.02 mol
What is ΔH for the hydrolysis of ATP to ADP and phosphate= ΔH/mol=618.64 J/K/0.02 mol=30,932 Joules/mol or 30.932 kJ/mol
Add Answer to:
One hundred milliliters of 0.200 M ATP is mixed with an ATPase in a Dewar at...

3. (4 pts) Living organisms use energy from the metabolism of food to create an energy-rich molecule called adenosine triphosphate (ATP). The ATP then acts as an energy source for a variety of reactions that in living organisms must carry out to survive. ATP provides energy through its hydrolysis, which can be symbolized as follows: ATP(aq) + H2O(l) → ADP(aq) + Pin(aq) &Gorun =-30.5 kJ where ADP represents adenosine diphosphate and Pm represents an inorganic phosphate group (e.g., HPO,). In...

Living organisms use energy from the metabolism of food to create an energy rich molecule called adenosine triphoshpate (ATP). the ATP then acrs as and energy source for a variegty of reactions that the living organism must carry oyut to survive. ATP provides energy through its hydrolysis, which can be symbolized as follows: ATP(aq)+H2O(l) --> ADP(aq)+Pi(aq) with a delta G of the reaction being =-30.5 kj. Where ADP represents adenosine diphosphate and Pi represents in inorganic phosphate group (such as...

1) One hundred (100) ml of a 1.00 M solution of HCl is diluted with water to prepare a 0.200 M solution. What is the volume of the resulting 0.200 M solution? Or asked another way, to what volume must the original solution be diluted? (3 points) 2) Lithium hydroxide, LiOH, is used in spacecraft to absorb the carbon dioxide exhaled by astronauts. Given 1.3 kg of LiOH, how many kg of CO2 can be absorbed? (10 Pts. The reaction...
