hills function models how the amount of oxygen bound to hemoglobin in the blood depends on oxygen concentration, p, in the surrounding tissues. in its most general form hills function models the fraction of hemoglobin molecules in blood that are bound to oxygen by using the following formula, where k is a positive constant, and n is a positive integer.\n\n f(p)=\frac{p^{n}}{k^{n}+p^{n}} \n\n(a) calculate ( f(p) ).\n(b) show that ( f(p)>0 ) for all ( p>0 ). this result means that increasing the oxygen concentration always increases the fraction of hemoglobin molecules that are bound to oxygen.\n\n(a) ( f(p)= )

Answer

Explanation:

Step1: Apply the quotient rule

The quotient rule states that if (y = \frac{u}{v}), then (y^\prime=\frac{u^\prime v - uv^\prime}{v^{2}}). Here, (u = P^{n}), (u^\prime=nP^{n - 1}), (v=k^{n}+P^{n}), and (v^\prime=nP^{n - 1}). [ \begin{align*} f^\prime(P)&=\frac{nP^{n - 1}(k^{n}+P^{n})-P^{n}(nP^{n - 1})}{(k^{n}+P^{n})^{2}}\ \end{align*} ]

Step2: Simplify the numerator

Expand the numerator: (nP^{n - 1}(k^{n}+P^{n})-P^{n}(nP^{n - 1})=nP^{n - 1}k^{n}+nP^{2n - 1}-nP^{2n - 1}) After simplifying the numerator (the (nP^{2n - 1}) terms cancel out), we get (nP^{n - 1}k^{n})

Answer:

(f^\prime(P)=\frac{nP^{n - 1}k^{n}}{(k^{n}+P^{n})^{2}})
