3 You re hanging out on your sofa not being very active so the concentration of ATP in your skeletal muscles rises ATP concentrations are held in tight equilibrium in most living systems so your body does not allow this increase However your body also does not want to lose all of the energy that is currently being held in these ATP molecules What will your body do to lower the ATP concentration while also retaining the energy held in that ATP molecule hint The answer is has nothing to do with sugars or fats 4 The membrane is known for self assembling but it is also known for only self assembling into a sphere and not into a flat plane Explain why the membrane is able to self assemble and why this self assembly results in a sphere and not a flat plane
