PROBLEMS IN PHOTOSYNTHESIS 



K - X C 



<P = 



K 



Co

as K is equal to the total chlorophyll and A' — x corresponds to the bound 

 chlorophyll. 



TABLE 17 

 Removed Oo capacity and quantum requirement 



It is now possible to calculate the chlorophyll content C^ of the cells from 

 two determinations of (p during stoichiometric O2 production. When y 

 ix\ O2 are produced after / min, 



C = C,- y (37) 



and hence, according to equation 36 



Co — y 



or 



f = 



Co = 



y

However, the renewed formation of the chlorophyll-carrier-substance, OC' 

 curring at the velocity constant A, has not been taken into consideration 

 Therefore, equation 37 has to be corrected to 



C = Co — y -\- kt 

 Hence, instead of equation 38 we have 



Co - {y - kt) 



(f =

If (fi and (p2 are determined at the times /i and /2, two equations 41 are ob- 

 tained. After elimination of k we find 



Co =
