Why are photosynthesis and cellular respiration considered complementary processes?

Photosynthesis uses energy to make glucose, glycolysis uses glucose to make energy

Explanation:

The simplified equations of photosynthesis and glycolysis are as follows:

Photosynthesis:

carbon dioxide + water + (energy) → glucose + oxygen

Glycolysis:

glucose → pyruvic acid + energy

Photosynthesis uses carbon dioxide, water, and light energy from the sun to generate glucose, which is used as a source of energy for cellular processes.

Glycolysis is the first stage of cellular respiration, which uses glucose to generate energy in the form of ATP.

the electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, x-rays, and gamma-rays.

the overall balanced equation

6co2 + 6h2o > c6h12o6 + 6o2

sunlight energy

where: co2 = carbon dioxide

h2o = water

light energy is required

c6h12o6 = glucose

o2 = oxygen
