The biochemical conversion of Glucose, C6H12O6, into pyruvic acid, C3H4O3, is an important step in the TCA (Kreb’s) cycle which forms a part of the metabolic breakdown of glucose (to produce energy). C6H12O6 (s) + O2 (g) → 2C3H4O3(l) + 2H2O (l) glucose oxygen pyruvi...

Hi Bob, Thank you for responding so quickly. And sorry to hear about your allergies. They are not fun! The exact question was : normalize the following functions in the interval 0 to infinity: a) e^-5x. The answer my instructor has is 10^1/2 e ^-5x as the answer but I don'...

Physics
Can someone please show me step by step how to normalize e^-5x in the interval (0, infinity)? I have read a lot of different books etc but need it explained to me in plain English or showed to me step by step because I am just not getting it. Thank you
