Question

what is the first step of photosynthesis? carbon fixation light reactions glycolysis photolysis

Explanation:

Photosynthesis has two main stages. The first is the light - dependent reactions (light reactions) which capture energy from sunlight. Carbon fixation is part of the Calvin cycle (light - independent reactions). Glycolysis is part of cellular respiration. Photolysis occurs during the light reactions but is just one process within it.

Answer:

light reactions
