carbon dioxide enters the stroma of the chloroplast where it binds to RuBP (a 5 carbon compound) to form an unstable 6 carbon compound which immediataly breaks down to form 2 GP (glycerate 3-phosphate). Some of the ATP and NADPH from the light dependant reaction are used to convert GP into TP (glyceraldehyde 3-phosphate). The NADPH is reduced to NADP which is returned to the light dependant reaction.
pairs of the TP compounds are joined to form hexose sugar which is then polymerized to form starch which is stored by the plant.
it is important to note that not all of the TP is used to form hexose.
of the 12 TP formed, 10 TP is returned to join with RuP in the cell to regenerate RuBP to continue the cycle (this is where the rest of ATP is used)

∙ 14y agoHydrogen atoms released from water are added to carbon dioxide molecules so that carbon oxygen bonds are broken and carbon atoms can join together. Carbon dioxide consists of a carbon atom attached to two oxygen atoms. That way, a carbon atom joins two other carbon atoms. One of the hydrogen atoms joins the carbon atom and one of the hydrogen atoms joins with the oxygen atom. You end up with the carbon atom attached to four different atoms.

What cycle is also called the dark reaction in photosynthesis?
The Calvin cycle, or carbon fixation, occurs during the dark reactions of photosynthesis.
A place where dark reactions occur?
The dark reaction of photosynthesis occurs in the stroma of the chloroplasts.. This is energy production without the aid of sunlight
What occurs in the stroma of te chloroplast?
Many chemical reactions take place.Most importantly,dark reaction.
What happens during each of the two stages of photosynthesis?
These stages are called the light reactions and the dark reactions. The light reactions take place in the presence of of light. The dark reactions do not require direct light, however dark reactions in most plants occur during the day.
What two types of reactions occur during photosynthesis?
The two reactions which occur during photosynthesis are light reaction and dark reaction. Light reaction takes place only in the presence of light. Dark reaction can occur with or without light.
What cycle is also called the dark reaction in photosynthesis?
The Calvin cycle, or carbon fixation, occurs during the dark reactions of photosynthesis.
What is a place where dark reactions occur during photosynthesis called?
stroma
Do the of photosynthesis ocdark reactions cur only at night?
No, dark reactions occurs in day light & as well as in night. It cant be called as dark reaction, its a Calvin cycle.

What is the role of energy in photosynthesis?
The energy formed in the light reactions of photosynthesis is used to convert carbon dioxide into glucose during the Calvin cycle (dark reactions).
What is wrong in saying that dark reaction of photosynthesis occurs at night?
The so-called "dark reactions" are those that occur independently of the absorption of sunlight, but only when the "light reactions" are providing the molecules required. This only occurs when there is sunlight available.
What two types of reactions occur during photosynthesis?
The two reactions which occur during photosynthesis are light reaction and dark reaction. Light reaction takes place only in the presence of light. Dark reaction can occur with or without light.

True or false The light reactions of photosynthesis can occur only under light conditions and the dark reactions can occur only during the dark hours?
false; dark reaction is independent of light
The dark reactions of photosynthesis are those that?
Only occur in the dark.
