ATP

All animals in some way rely on plants for their energy

Plants provide the water and CO2 that animals need to carry out respiration

All eukaryotic organisms carry out respiration in the presence of O2

The energy that powers living systems ultimately comes from the sun

They are reduced

They are what is used during carbon fixation in photosynthesis

They have a full complement of electrons

They are oxidized

water, ADP and NADP+

carbon dioxide, PGAL (phosphoglyceraldehyde), and H2

O2, ATP and NADPH
