Where do the light-independent reactions take place in CAM photosynthesis?
Where do the light-independent reactions take place in CAM photosynthesis?
The light-independent reactions of photosynthesis take place within the stroma. It contains enzymes that work with ATP and NADPH to “fix” carbon from carbon dioxide into molecules that can be used to build glucose. The chloroplast’s own genetic material (separate from that of the cell) is also stored in the stroma.
Where do the light-independent reactions take place in CAM photosynthesis quizlet?
The light-independent reactions (also called the Calvin Cycle or the dark reactions) take place in the stroma. The stroma is the fluid that fills the chloroplast.
What happens in the light independent stage of photosynthesis?
In the light-independent reactions or Calvin cycle, the energized electrons from the light-dependent reactions provide the energy to form carbohydrates from carbon dioxide molecules. The light-independent reactions are sometimes called the Calvin cycle because of the cyclical nature of the process.
How do CAM plants undergo photosynthesis?
CAM is an abbreviation of crassulacean acid metabolism. In this type of photosynthesis, organisms absorb sunlight energy during the day then use the energy to fix carbon dioxide molecules during the night.
What is the function of the light-independent reactions?
The light-independent reactions use the ATP and NADPH from the light-dependent reactions to reduce carbon dioxide and convert the energy to the chemical bond energy in carbohydrates such as glucose.
In what part of the chloroplast do the light-independent reactions occur?
chloroplast stroma
Once the light reactions have occurred, the light-independent or “dark” reactions take place in the chloroplast stroma.
Where do the light-independent reactions take place in C3 photosynthesis quizlet?
The light-independent reactions take place in the chloroplast stroma. 3. ATP is consumed by light-independent reactions.
What are the 7 steps of light-independent reactions?
Terms in this set (7)
- (1st Time) Energy is absorbed from the sun.
- Water is broken down.
- Hydrogen ions are transported across the thylakoid membrane.
- (2nd Time) Energy is absorbed from the sun.
- NADPH is produced from NADP+.
- Hydrogen ions diffuse through the protein channel.
- ADP becomes ATP.
Which best describe light-independent reactions?
Which best describes light-independent reactions? They are the first stage of photosynthesis. They utilize the energy stored in ATP and NADPH.
Do CAM plants need light for photosynthesis?
CAM plants leave their stoma closed during the day and open them at night instead. However, because there is no sunlight at night for photosynthesis, CAM plants need a method to hold onto the carbon dioxide until the day time.
How is CAM photosynthesis different than C4?
The main difference between C4 and CAM plants is the way they minimize water loss. C4 plants relocate the CO2 molecules to minimize photorespiration while CAM plants choose when to extract CO2 from the environment. Photorespiration is a process that occurs in plants where oxygen is added to RuBP instead of CO2.
