How do the light dependent reactions of photosynthesis relate to the Calvin cycles?
The light dependent reactions create compounds which store the energy necessary for the Calvin Cycle to take place. This energy is stored in ATP (Adenosine Triphosphate), among other compounds, during the LDR. In the Calvin cycle, these are broken down, which releses energy. The energy released is used to create bonds between the parts of Glucose
Another way to explain it in a simpler way is, when the light reaction has gone through once, it has produced NADH and ATP. These are nessisary for the making of glucose which is what the Calvin cycle does. The NADH and ATP are what power the Calvin cycle.
What else can I help you with?
Where in the plant cell is the Calvin cycles occurring?
The Calvin cycle, a series of biochemical reactions that occur during photosynthesis, takes place in the stroma of the chloroplast, which is a compartment within the plant cell where photosynthesis occurs.
What are two staged of photosynthesis called?
Dark reaction or Calvin cycles and Light reaction
What is the Calvin cycles cofactors?
The Calvin cycle primarily uses several cofactors, including ATP and NADPH, which are produced during the light-dependent reactions of photosynthesis. ATP provides the necessary energy for the cycle, while NADPH supplies the reducing power needed for the conversion of 3-phosphoglycerate into glyceraldehyde-3-phosphate. Additionally, the enzyme ribulose bisphosphate carboxylase/oxygenase (RuBisCO) catalyzes the first step of carbon fixation, and magnesium ions often function as a cofactor for some of the enzymatic reactions within the cycle.
What explains how the Calvin cycle and the keeps cycle differ?
The Calvin cycle, part of photosynthesis, focuses on converting carbon dioxide into glucose using ATP and NADPH produced in the light-dependent reactions. In contrast, the Krebs cycle (or citric acid cycle) is a key component of cellular respiration, where it breaks down acetyl-CoA to produce ATP, NADH, and FADH2 while releasing carbon dioxide as a waste product. While both cycles involve a series of enzymatic reactions and contribute to energy production, they operate in different cellular contexts and serve distinct metabolic purposes.
Which two cycle are linked by the production and utilization of carbon dioxide where do these cycles occur?
The Calvin Cycle in Photosynthesis and The Krebs Cycle in Cellular Respiration. The Calvin Cycle occurs in chloroplasts and The Krebs Cycle occurs in the Mitochondria.
What are the three things the Calvin cycle requires?
Light, water and carbon dioxide are required in the calvin cycle, 3 photons, 3 water molecules, and 3 carbon dioxide, although most people refer to photosynthesis and making glucose, requiring 2 calvin cycles
Are season cycles a density- dependent factor?
Crowding, disease, and competition are all density-dependent limiting factors EXCEPT, seasonal cycles. Seasonal cycles are NOT a density- dependent limiting factor.
Why does it take six cycles of the stromal reactions to produce one molecule of glucose?
It takes six cycles of the Calvin cycle (dark reactions) to produce one molecule of glucose because each cycle fixes one molecule of carbon dioxide. Glucose contains six carbons, so it requires six cycles to fix all six carbons needed to form one molecule of glucose.
What do Calvin cycles do?
Converts carbon dioxide to glucose
What is silmilar between the citric acid cycle and the Calvin cycle?
Both the citric acid cycle and the Calvin cycle are metabolic pathways found in living organisms. They both involve a series of chemical reactions that help in the production of energy or organic compounds. While the citric acid cycle occurs in the mitochondria and is involved in cellular respiration, the Calvin cycle takes place in the chloroplasts and is involved in photosynthesis.
What is needed by the Calvin Cycle?
The Calvin cycle is a 'light independent cycle' that takes place in the chloroplasts. In this cycle, water and carbon dioxide is converted into organic compounds. The key enzyme involved is Rubisco.
Which molecule from the Calvin Cycle is used to replenish the five-carbon sugar RuBP which is used a the beginning of the cycles?
The molecule used to replenish RuBP in the Calvin Cycle is phosphoglycerate (PGA). PGA is converted to RuBP through a series of enzymatic reactions, allowing the cycle to continue and fix more carbon dioxide.
