What is the relationship between light intensity and ATP production?

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.

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
