dark reaction

It is one of the light-independent reactions or dark reactions.

The process they developed effectively separates the light and dark reactions that occur during photosynthesis.

Essentially the dark reactions involve the reduction of carbon dioxide to form carbohydrate.

Photosynthesis is really two interrelated processes that biochemists call the light and dark reactions.

Temperature - The temperature determines the speed of respiration and the dark reaction.

Yet Schapiro refused to go along with the idea "that there was never any choice in Russia between dark reaction and red revolution."

Two cycles of biochemical reactions constitute the basis of plant production, the light reaction and the dark reaction.

Despite its widespread names (both light-independent and dark reactions), these reactions do not occur in the dark or at night.

They are activated in the light (which is why the name "dark reaction" is misleading), and also by products of the light-dependent reaction.

One takes place only in the presence of light and is called the light reaction; the other can occur with or without light and is called the dark reaction.

While named "the dark reactions", in most plants, they take place in the light, since the dark reactions are dependent on the products of the light reactions.

From this meaning evolved the meaning of writing that reveals more of the writer's heart and motivations, particularly the darker reactions, and the events that are normally kept secret.

Photosynthesis is divided into two stages-the light reactions, where water is split to produce oxygen, and the dark reactions, or Calvin cycle, which builds sugar molecules from carbon dioxide.

Because chloroplast ATP synthase projects out into the stroma, the ATP is synthesized there, in position to be used in the dark reactions.

The dark reaction or Calvin cycle ties atmospheric carbon dioxide and uses NADH and ATP to convert it into sucrose.

In the dark reaction, the NADPH and ATP are used to convert carbon dioxide to carbohydrates - a well-known process that forms the 'Calvin Cycle'.

They take light energy and store it in NADPH, a form of NADP, and ATP to fuel the dark reactions.

These dark reactions are closely coupled to the thylakoid electron transport chain as reducing power provided by NADPH produced in the photosystem I is actively needed.

Other actinometers include malachite green leucocyanides, vanadium(V)-iron(III) oxalate and monochloroacetic acid, however all of these undergo dark reactions, that is, they react in the absence of light.

A low temperature combined with a high intensity of sunlight means that NADH and ATP heap up but cannot be converted into glucose because the dark reaction cannot process them swiftly enough.

Most of the G3P molecules are recycled back into RuBP using energy from more ATP, but one out of every six produced leaves the cycle-the end product of the dark reactions.

Oxygenic and anoxygenic photosynthesizing organisms undergo different reactions either in the presence of light or with no direct contribution of light to the chemical reaction (colloquially called "light reactions" and "dark reactions", respectively).

The enzyme is integrated into thylakoid membrane; the CF-part sticks into stroma, where dark reactions of photosynthesis (Also called the light-independent reactions or the Calvin cycle) and ATP synthesis take place.

However, although light-independent reactions are, by convention, also called dark reactions, they are not independent of the need of light, for they are driven by ATP and NADPH, products of light.

The process of photorespiration, also known as C2 cycle, is also coupled to the dark reactions, as it results from an alternative reaction of the Rubisco enzyme, and its final byproduct is also another glyceraldehyde-3-P.
