WebA fundamental mystery of plant cell biology is the occurrence of “stromules,” stroma-filled tubular extensions from plastids (such as chloroplasts) that are universally observed in … WebJul 12, 2024 · Chloroplast photosystems generate ATP and NADPH during photosynthesis. To fix one CO 2 molecule, three ATP molecules and two NADPH molecules (ATP/NADPH = 1.5) are consumed by the Calvin-Benson-Bassham (CBB) cycle (Fig. 1 B). However, the linear electron flow (LEF) only generates ATP and NADPH at a ratio of 1.28.
