Question | Answer |

There are two stages of photosynthesis: the light-[...] reactions, and the light-[...] reactions. | There are two stages of photosynthesis: the light-dependent reactions, and the light-INdependent reactions. |
The light-independent reactions of photosynthesis are also known as the [...] cycle (after Melvin Calvin of UC Berkeley). | The light-independent reactions of photosynthesis are also known as the Calvin cycle (after Melvin Calvin of UC Berkeley). |
The light-independent reactions were also known as the [...] reactions, but this is misleading. They can happen in the light or the dark. | The light-independent reactions were also known as the dark reactions, but this is misleading. They can happen in the light or the dark. |
The product of the light-independent reactions is a [...]-carbon sugar with a phosphate group on the end (glyceraldehyde-3-phosphate; G3P | The product of the light-independent reactions is a 3-carbon sugar with a phosphate group on the end (glyceraldehyde-3-phosphate; G3P |
Glyceradehyde-3-phosphate (G3P), the end-product of the light-[...] reactions can be used as an energy source to power the cell, or it can be used to create larger sugars such as glucose (a 6-carbon sugar). | Glyceradehyde-3-phosphate (G3P), the end-product of the light-independent reactions can be used as an energy source to power the cell, or it can be used to create larger sugars such as glucose (a 6-carbon sugar). |
The Calvin cycle uses [...] and [...] to rip carbons from carbon dioxide and use them to assemble a 3-carbon sugar (glyceraldehyde-3-phosphate), which can then be used to create glucose. | The Calvin cycle uses NADPH and ATP to rip carbons from carbon dioxide and use them to assemble a 3-carbon sugar (glyceraldehyde-3-phosphate), which can then be used to create glucose. |
The Calvin cycle occurs in the [...] (the fluid part; not the inner membranes) of the chloroplast. | The Calvin cycle occurs in the stroma (the fluid part; not the inner membranes) of the chloroplast. |
The step where a plant converts glyceraldehyde-3-phosphate (G3P) into a larger carbohydrate (such as glucose) is NOT technically part of the [...] cycle (light independent reactions), but K12 lumps it in with them (probably to simplify things). | The step where a plant converts glyceraldehyde-3-phosphate (G3P) into a larger carbohydrate (such as glucose) is NOT technically part of the Calvin cycle (light independent reactions), but K12 lumps it in with them (probably to simplify things). |
The Calvin cycle needs: •[...] • ATP, and • NADPH | The Calvin cycle needs: • carbon dioxide • ATP, and • NADPH |
The Calvin cycle needs: • carbon dioxide • [...], and • NADPH | The Calvin cycle needs: • carbon dioxide • ATP, and • NADPH |
The Calvin cycle needs: • carbon dioxide • ATP, and • [...] | The Calvin cycle needs: • carbon dioxide • ATP, and • NADPH |
A by-product of the Calvin cycle is [...] gas. This is the leftover [...] from the carbon dioxide (the carbon-source for the Calvin cycle). | A by-product of the Calvin cycle is oxygen gas. This is the leftover oxygen from the carbon dioxide (the carbon-source for the Calvin cycle). |
Dr. Melvin Calvin of UC Berkeley worked out the Calvin cycle using [...] carbon isotopes. This let him see which molecules the carbon atoms were entering (because they would show up as [...]). He received the Nobel Prize in Chemistry in 1961. | Dr. Melvin Calvin of UC Berkeley worked out the Calvin cycle using radioactive carbon isotopes. This let him see which molecules the carbon atoms were entering (because they would show up as radioactive). He received the Nobel Prize in Chemistry in 1961. |
