The reactions that make up the process of photosynthesis can be divided into light-dependent reactions, which take place in the thylakoids, and light-independent reactions (also known as dark reactions or the Calvin cycle), which take place in the stroma.

Oct 19, 2023 · The head of the railroad worm glows red, while its body glows green. Different luciferases cause the bioluminescence to be expressed differently. Some organisms emit light continuously. Some species of fungi present in decaying wood, for instance, emit a fairly consistent glow, called foxfire.
Jan 18, 2022 · Light-dependent reaction is the series of biochemical reactions in photosynthesis requiring light energy that is captured by light-absorbing pigments (such as chlorophyll) to be converted into chemical energy (ATP and NADPH).
Light (visible, UV, and IR) is essential to life on Earth and is an integral part of the human experience. Our understanding of how the human body responds to light is constantly growing and evolving. There are three main systems in our bodies that utilize light: The Visual System – for vision.
The light reactions of photosynthesis liberate oxygen, and more oxygen dissolves in the cytosol of the cell at higher temperatures. Therefore, high light intensities and high temperatures (above ~ 30°C) favor the second reaction and result in photorespiration.
Figure \(\PageIndex{2}\): Light reactions harness energy from the sun to produce chemical bonds, ATP, and NADPH. These energy-carrying molecules are made in the stroma where carbon fixation takes place.

Chemical reactions that take place inside living things are called biochemical reactions. The sum of all the biochemical reactions in an organism is called metabolism. Metabolism includes both exothermic (energy-releasing) chemical reactions and endothermic (energy-absorbing) chemical reactions.
