Which molecule is split apart during the light reactions in photosynthesis

The light reaction occur in the thylakoid membranes. Water is split, providing a source of electrons and giving off O2 gas as a by-product. Light energy absorbed by chlorophyll molecules built into the membranes is sued to drive the transfer of electrons and H+ from water to NADP+, reducing it to NADPH.

the answer is water if for apex

interphase   is the cell cycle stage in which the cell acquires nutrients, creates and uses proteins and other molecules and starts the process of cell division by replicating the dna. it is the longest stage in the eukaryote cell cycle.

the following   can go wrong during interphase:   a base pair could be mismatched during the duplication process causing a mutation.   correct answer: c
