What is the relationship between light intensity and ATP production?

Answers

Answer:

Abstract

Explanation:

Among the primary biochemical changes evoked by illumination in dark-grown mycelia of Trichoderma viride is the temporal rise in the intracellular level of ATP. We investigated the dependence of ATP changes on light intensity and exposure. Marked changes in the intracellular ATP levels occurred within 10 min of the onset of illumination and their rapidity was proportional to the light intensity. Statistically significant changes in the intracellular levels of ATP were observed at light intensities in the range of 0.9–2.5 klx with the maximum increase (150% above the intracellular level of ATP in the dark control) at 1.2 klx.
