I need the excel code of the following assignment. Please write the formula in excel.

Energetics and Bacterials Growth

page $150-160$

Skep I. Identify elections donor

step II: Identify elutron acceptor

step II Identify Nitrogen source

step IV Identify $G_d^0=$ for donor fint it in

table $2\mathrm{.}3$ page $136$

step I. Identify $G_a^{O^{\text{'}}}=$ find in table $2\mathrm{.}2$ or $2\mathrm{.}4$

step IV identify $G_p=35\mathrm{.}09-G^{0}dif$ Hytrotrophic,

$GP=113\mathrm{.}8if$ Autotrophic cell $D$

Step $8.G_r=G_a^{0!}-1G_d^{0!}$

$($ilirate$)$

step $9$ assume efficiency: $(=0\mathrm{.}4-0\mathrm{.}6)$

step $10,A=\frac{G_p}{{}^n}+\frac{G_{P_C}}{},n=+1$ if $G_p>0$

$*G_r,n=-1$ if $G_p<mn>0</mn>$

stepll $f_s=\frac{1}{1+A}$ and $f_e=1-f_s$
