Complex chemical processes such as photosynthesis occur in a controlled series of steps with the of ?

Chlorophyll and sun light.

Explanation:

Photosynthesis:

It is the process in which in the presence of sun light and chlorophyll by using carbon dioxide and water plants produce the oxygen and glucose.

Carbon dioxide + water + energy →   glucose + oxygen

water is supplied through the roots, carbon dioxide collected through stomata and sun light is capture  by chloroplast.

Chemical equation:

6H₂O + 6CO₂ + energy  →   C₆H₁₂O₆ + 6O₂

The glucose is converted into pyruvate and produces ATP through cellular respiration and produces oxygen.

the answer is b.) hydrogen bonds between bases.
