Where does the light reaction of photosynthesis take place quizlet?
– The light reactions take place inside the thylakoids of chloroplasts. – The light reactions produce chemical energy in the form of NADPH and ATP.
What is the purpose of photosynthesis?
Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel.
What is the primary function of light energy in plants?
Photosynthesis is a process carried out by green plants, algae, and some photosynthetic bacteria. It involves capturing energy in sunlight and using it to synthesize carbohydrates like glucose, which store energy and provide structural support for the cell.
What is the primary function of the Calvin cycle light-independent reactions of photosynthesis *?
The basic function of the Calvin cycle is the conversion of solar energy to chemical energy. Select the most accurate statement describing the basic function of the light reactions of photosynthesis.
What is the primary purpose of splitting of water in the light reactions?
The primary purpose of splitting water in the light dependent reactions of photosynthesis is to release electrons for the electron transport chain. These electrons will then be utilized to create a proton gradient, to synthesize ATP. The final electron acceptor of these electrons is NADP which will form NADPH.
Where do light reactions occur in the process of photosynthesis?
In plants, the so-called “light” reactions occur within the chloroplast thylakoids, where the aforementioned chlorophyll pigments reside. When light energy reaches the pigment molecules, it energizes the electrons within them, and these electrons are shunted to an electron transport chain in the thylakoid membrane.
What is the primary function of the cyclic electron flow?
In higher plants, the generation of proton gradient across the thylakoid membrane (ΔpH) through cyclic electron flow (CEF) has mainly two functions: (1) to generate ATP and balance the ATP/NADPH energy budget, and (2) to protect photosystems I and II against photoinhibition.
What is the primary function of the Calvin cycle quizlet?
The light reactions provide ATP and NADPH to the carbon fixation step of the Calvin cycle, and the cycle provides water and electrons to the light reactions. C) The light reactions supply the Calvin cycle with CO₂ to produce sugars, and the Calvin cycle supplies the light reactions with sugars to produce ATP.
What is the purpose of water in photosynthesis?
During the process of photosynthesis, six molecules of carbon dioxide and six molecules of water react in the presence of sunlight to form one glucose molecule and six molecules of oxygen. The role of water is to release oxygen (O) from the water molecule into the atmosphere in the form of oxygen gas (O2).
What is the primary function of the Calvin cycle in photosynthesis quizlet?
Terms in this set (7)
The Calvin cycle takes gaseous CO2 and converts it into glucose to store energy captured during the light reactions.
What do the light reactions of photosynthesis supply the Calvin cycle with?
The light reactions produce carbon dioxide, ATP, NADPH, all of which are used in the Calvin cycle. The light reactions produce ATP and NADPH, both of which are used in the Calvin cycle.
Why does the light-dependent stage of photosynthesis require light?
Just as the name implies, light-dependent reactions require sunlight. … Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH. The Calvin cycle, which takes place in the stroma, uses energy derived from these compounds to make GA3P from CO2.
