HOPE IT HELPS YOU '_'

The splitting of water during the light-dependent reaction. The splitting of water serves to replace these lost electrons. 
Hope it helped :)

Ifound this on google “increases in temperature increase molecular activity, and can result in a higher rate of collisions between enzymes and substrates. if the temperature rises too high, however, the enzymes could become denatured, and the positive effects of the temperature increase could be nullified.” for more information go to the website below › i hope this you for what your looking for. can you plz mark me brainliest?

Where are the options?
