Cell Biology/Energy supply/Light Dependent Reactions The light-dependent reactions begin in photosystem II. When a chlorophyll a molecule within the reaction center of PSII absorbs a photon, an electron in this molecule attains a higher energy level. Because this state of an electron is very unstable, the electron is transferred from one to another molecule creating a chain of redox reactions, called an electron transport chain (ETC).

The Light-Dependent and Light-Independent Reactions The ATP and NADPH generated in the earlier light reactions are strong reducing agents (electron donors) and are able to donate the necessary electrons to make carbohydrates. Altogether, the conversion of one mole of CO2 to one mole of CH2O requires two moles of NADPH and three moles of ATP.

Light and Dark Reactions in Photosynthesis Photosynthesis can be summarized with this formula: 6CO2 + 6H2O + sunlight (light energy) → C6H12O6 + 6O2. If you need a longer review, check out our lesson on photosynthesis before reading on. The light-independent or dark reactions happen in the stroma of the chloroplasts. This is also known as the Calvin Cycle. Since these processes can only happen in the chloroplast (a chlorophyll filled plastid in green plants), photosynthesis can only happen in green plants!

Photosynthesis: How Plants Transform Energy from the Sun The Light Reactions Reactions that depend on light occur during the first phase of the process of photosynthesis. These processes take place in the grana that house chlorophyll. Molecules of chlorophyll absorb light. Energy from the absorbed light causes reactions that result in the formation of a substance called ATP. Oxygen is released into the atmosphere. In fact, the largest source of free oxygen in the atmosphere is as a byproduct from photosynthesis. The Dark Reactions The second phase of the process of photosynthesis can occur in light or darkness.

Bioluminescence Questions and Answers All bioluminescence comes from energy released from a chemical reaction. This is very different from other sources of light, such as from the sun or a light bulb, where the energy comes from heat. In a luminescent reaction, two types of chemicals, called luciferin and luciferase, combine together.

Light-independent reactions The light-independent reactions of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose. These reactions occur in the stroma, the fluid-filled area of a chloroplast outside of the thylakoid membranes. These reactions take the products (ATP and NADPH) of light-dependent reactions and perform further chemical processes on them. There are three phases to the light-independent reactions, collectively called the Calvin cycle: carbon fixation, reduction reactions, and ribulose 1,5-bisphosphate (RuBP) regeneration. Despite its name, this process occurs only when light is available. Plants do not carry out the Calvin cycle by night.

Biosynthesis Once in the mesophyll cells, CO 2 diffuses into the stroma of the chloroplast, the site of light-independent reactions of photosynthesis. These reactions actually have several names associated with them. Other names for light-independent reactions include the Calvin cycle, the Calvin-Benson cycle, and dark reactions. The most outdated name is dark reactions, which can be misleading because it implies incorrectly that the reaction only occurs at night or is independent of light, which is why most scientists and instructors no longer use it.

- The dark reactions, which are also referred to as the light independent (because they don't need light) or carbon fixing reactions (because they fix carbon from carbon dioxide into carbohydrate molecules), occur in the stroma surrounding the thylakoids.
