In what organelle doesphotosynthesis occur?

NADPH and the hydrogen ions made in the light reactions are used to split a phosphate off of each (putting phosphates back to make more ATP) and to provide the energy and hydrogen to turn the remaining chemical into glyceraldehyde phospate, also called phosphoglyceraldehyde, or PGAL.

Chemistry for Biologists: Photosynthesis

Anaerobic respiration begins with glucose in the cell. A glucose molecule thathas 6 carbons is broken down into 2 PGAL (phosphoglyceraldehyde). Thisrequires 2 ATP. The 2 PGAL are then converted into 2 pyruvic acid and this reactionproduces 4 ATP. Hydrogen's come off the glucose as it is being broken down and areaccepted by NAD. So far we have a net gain of 2ATP. Don't forget that organisms arecarrying this process on since they need the ATP to survive. If we are talking aboutbacteria and yeast, the 2 ATP are converted to 2 ethyl alcohol and 2 carbondioxide. The net yield of ATP is 2 and the waste products of anaerobicrespiration are ethyl alcohol and carbon dioxide. These waste products are used bythe brewing and baking industries. This special type of anaerobic respiration that occursin the cytoplasm of yeast and bacteria is call alcoholic fermentation. and nets 2ATP.

H+ ions build up inside the thylakoid and will be used later in photosynthesis.
The Calvin cycle takes place in the stroma.
The Calvin Cycle
In the electron transport chain, an energized electron is passed from protein to protein, and the energy is released slowly.

You can imagine that making a complex carbohydrate from a molecule of CO2 would be a large task for a cell, so the light-independent reactions in the stroma of the chloroplast break down the complicated process into small steps.
Step #1
Carbon fixation - The carbon atom from CO2 bonds with a five-carbon sugar called ribulose biphosphate to form an unstable six-carbon sugar.
Step #2
Formation of 3-Carbon molecule - The six-carbon sugar formed in the first step immediately splits to form 2 three-carbon molecules.
Step #3
Use of ATP and NADPH - A series of reactions involving ATP and NADPH from the light-dependent reactions converts the three-carbon molecules into PGAL.
Step #4
Sugar production - One out of every six molecules of PGAL is transferred to the cytoplasm and used in photosynthesis of sugars and other carbohydrates.

After three rounds of the cycle, six molecules of PGAL are produced.
Step #5
RuBP is replenished - five molecules of PGAL, each with 3 carbon atoms, produce three molecules of five-carbon RuBP.

This replenishes the RuBP so that the cycle may continue.
In photosystem I, chlorophyll and other light-absorbing molecules in the thylakoid membrane also absorb energy from sunlight.
