if you consider the combined processes of photosynthesis and cellular respiration, the electrons found in h₂o at the beginning of the light reactions end up attaching to ______
nadph to make new glucose
pyruvate to make ethanol
electron transport carriers to make o₂
o₂ to make new h₂o

Explanation:

In photosynthesis, water is split in the light - reactions, releasing electrons. These electrons go through a series of processes and ultimately in cellular respiration, the electrons are used in the electron - transport chain to reduce oxygen to water.

Answer:

D. O₂ to make new H₂O
