If there is no light coming into the chloroplast how will this affect the Calvin cycle?
Calvin cycle does not need light.So there is no affect.
Which two cycles are linked by the production and utilization of carbon dioxide. where do these cycles occur?
The Calvin cycle takes place in the stroma of the chloroplast. Carbon dioxide enters the stroma of the chloroplast to combine with the five-carbon compound called ribulose1, 5-Biphosphate to form two molecules of a three-carbon compound called 3-Phosphoglyceric acid. This reaction is catalyzed by an enzyme called Ribulose bi-phosphate Carboxylase.
In the chloroplast, the thylakoid membranes are the sites of the light reactions, whereas the Calvin cycle occurs in the stoma. The light reactions use solar energy to create ATP and NADPH, which supply chemical energy and reducing power, respectively, to the Calvin cycle. The Calvin cycle incorporates CO2 into organic molecules, which are converted to sugar.
The chloroplast is found in the plant and is key to photosynthesis. The chloroplast take in H20, CO2, and sunlight and give of Glucose (C6H12O6) and O2. It runs on two cycles known as the Calvin/Dark Cycle and the Light Dependent Cycle. The Light dependent cycle uses light and the dark cycle does not require light yet still occurs during the day scientists believe. Good Question! Hope that this helps.
There are stacks of thylakoids in the chloroplast, in the membrane of the the thylakoids light-dependent reactions occur, and in the thylakoid space (or cytoplasm of the thylakoid) the Calvin cycle (or light-independent reaction) occurs. If you haven't gotten this far into it, photosynthesis occurs in the chloroplast.
