light reaction is photolysis which mean using light or photon to lysis or break the water molecules into oxygen and hydrogen ion, H+.
Dark reaction or the calvin cycle uses hydrogen ion to convert carbon dioxide into glucose
The light reactions of photosynthesis produce ATP and NADPH, which are then used in the dark reactions (Calvin cycle) to convert carbon dioxide into sugars. The ATP and NADPH generated in the light reactions provide the energy and reducing power needed for the dark reactions to occur. In this way, the two sets of reactions are interdependent and work together to sustain the overall process of photosynthesis.
Calvin Cycle
The thiosulphate solution is stored in the dark to prevent it from reacting with light, which may cause the solution to decompose or lose its effectiveness. Light can catalyze the oxidation of thiosulphate, leading to a decrease in its concentration and affecting its accuracy as a reagent in chemical reactions.
Ether is stored in dark brown bottles to protect it from degradation caused by exposure to light. Light can trigger chemical reactions in ether molecules, leading to its degradation and the formation of harmful byproducts. Storing ether in dark brown bottles helps maintain its stability and quality over time.
Keeping the solution in the dark during iodometric titration helps prevent any unwanted reactions due to exposure to light, which could interfere with the accuracy of the titration results. Light can induce photoreactions that can alter the chemical species being titrated, leading to incorrect readings. Therefore, maintaining the solution in the dark helps ensure the reliability and precision of the titration.
The light reactions provide energy carriers for the dark reactions.
Differences: >light reactions occur in the thykaloid membranes, but dark occur in stroma >light reactions are light dependent, or they need light to take place, whereas dark reactions don't > dark reactions use the products of the light reactions >light reactions are the first step of photosynthesis and dark reactions are the second step Similarities: >both in photosynthesis Thats really the only similarity!!! hope this helps :)
The light reactions provide energy carriers for the dark reactions.
The light reactions provide energy carriers for the dark reactions.
The dark reactions that occur in plants are dependent on the light reactions because the dark reactions need ATP and NADPH. ATP and NADPH are energy molecules that dark reactions need to do their job.
False. The light reactions of photosynthesis require light to convert solar energy into chemical energy, while the dark reactions (Calvin cycle) do not directly rely on light and can occur in both light and dark conditions. However, the dark reactions are indirectly dependent on the products of the light reactions.
The dark reactions that occur in plants are dependent on the light reactions because the dark reactions need ATP and NADPH. ATP and NADPH are energy molecules that dark reactions need to do their job.
These stages are called the light reactions and the dark reactions. The light reactions take place in the presence of of light. The dark reactions do not require direct light, however dark reactions in most plants occur during the day.
Explain why plants are able to continue the dark reactions when they are not able to use the light reactions?
A dark reaction is done in the Calvin Cycle. Light is not needed at the time of the dark reaction but it also doesn't hinder the reaction if there is light at the time.So in short. Yes.
The light reactions provide energy carriers for the darl reactions.
The light reactions of photosynthesis require oxygen as a raw material to produce ATP and NADPH. The dark reactions (Calvin cycle) of photosynthesis do not directly require oxygen as a raw material, but they use the ATP and NADPH produced in the light reactions. Both light and dark reactions are involved in photosynthesis, but only the light reactions require oxygen as a raw material.
