What events occur in the light reactions of photosynthesis?
The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH. In plants, the light reactions take place in the thylakoid membranes of organelles called chloroplasts.
Which of the following events occurs in the light reactions of photosynthesis Quizizz?
The light reactions provide the Calvin cycle with oxygen for carbon fixation, and the Calvin cycle provides the light reactions with sugars to produce ATP.
What three events occur during the light reactions of photosynthesis quizlet?
The correct sequence of events in the light reactions is… absorption of sunlight, splitting of water, electrons flow down the electron transport chain, and ATP is made.
Which of the following occurs during the light reactions quizlet?
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. The light reactions produce ADP and NADP+, both of which are used in the Calvin cycle.
What are the 3 important events processes of light reaction?
The three major events that occur during the process of photosynthesis are: > Absorption of light energy by chlorophyll. > Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen.
Which of the events listed below occurs in the light reactions?
Which of the events listed below occur in the light reactions of photosynthesis? NADPH is reduced to NADP+.
What is the first process in the light-dependent reactions of photosynthesis?
In the first part of photosynthesis, the light-dependent reaction, pigment molecules absorb energy from sunlight. The most common and abundant pigment is chlorophyll a. A photon strikes photosystem II to initiate photosynthesis.
Which of the following occurs during the carbon reactions of photosynthesis?
Which of the following occurs during the carbon-fixation reactions of photosynthesis? Water is converted into hydrogen and water.
What are the steps of light reactions in order?
The light-independent reactions of the Calvin cycle can be organized into three basic stages: fixation, reduction, and regeneration.
Which of the following is the correct order of processes in photosynthesis?
The steps of photosynthesis can be summarized by the following equation: 6 CO2 (carbon dioxide) + 6 H2O (water) + Energy = C6H12O6 (glucose)+ 6 O2 (oxygen). The carbon from carbon dioxide combines with hydrogen and oxygen from water to form glucose, with oxygen and water as byproducts.
Which of the following reactions occur during the light reactions of photosynthesis quizlet?
During photosynthesis, the light reactions convert light energy to chemical energy. – Pigment molecules inside photosystem II and photosystem I absorb light energy from the sun. – The light reactions take place inside the thylakoids of chloroplasts.
Where do the light reactions of photosynthesis occur?
thylakoid membrane The light reactions of photosynthesis take place in the thylakoid membrane, whereas the dark reactions are located in the chloroplast stroma.
What are the major events that occur during the light-dependent reactions of photosynthesis quizlet?
The light-dependent reactions of photosynthesis generate the ATP needed for carbon fixation to occur. C4 and CAM pathways occur simultaneously at night in plants, such as cacti. Which is the correct reaction for photosynthesis?
Which events take place in the light-dependent reactions of photosynthesis quizlet?
Which events take place in the light-dependent reactions of photosynthesis? Light energy is captured by plants; light energy is converted to chemical energy.
Which event does not occur in light reactions?
Answer. Answer: C)CO2,reduced into C6H1206 .
Which list gives the products of the light reactions of photosynthesis group of answer choices?
The light reactions absorb light and harness the energy to power electron transfers. Most photosynthetic organisms capture visible light, although there are some that use infrared light. Products of these reactions are adenosine triphosphate (ATP) and reduced nicotinamide adenine dinucleotide phosphate (NADPH).
What is the process of light reaction?
“Light reaction is the process of photosynthesis that converts energy from the sun into chemical energy in the form of NADPH and ATP.”
Which process is part of the light reaction?
“Light reaction is the process of photosynthesis that converts energy from the sun into chemical energy in the form of NADPH and ATP.”
Which of these reactions occur in photosynthesis?
6. Which one chemical reaction occurs during photosynthesis? explanation – the chemical reaction that occurs during photosynthesis means Carbon dioxide is reduced and water is oxidised .
What are the 3 reactions of photosynthesis?
Once in the mesophyll cells, CO2 diffuses into the stroma of the chloroplast—the site of light-independent reactions of photosynthesis (Figure 13.6. 1). The light-independent reactions (also known as the Calvin cycle) can be organized into three basic stages: fixation, reduction, and regeneration (Video 13.6.

What happens during the light reactions?
During the light-dependent stage (“light” reactions), chlorophyll absorbs light energy, which excites some electrons in the pigment molecules to higher energy levels; these leave the chlorophyll and pass along a series of molecules, generating formation of NADPH (an enzyme) and high-energy ATP molecules.
Which of the following takes place during the light reactions?
During the light reactions, water is used and oxygen is produced. These reactions can only occur during daylight as the process needs sunlight to begin.

What occurs in the light-dependent reactions quizlet?
What happens during the light-dependent reactions? The light-dependent reactions use energy from sunlight to produce oxygen and convert ADP and NADP+ into the energy carriers ATP and NADPH. These reactions also produce oxygen as a by-product.
What occurs during the light-independent reactions of photosynthesis quizlet?
The light-dependent reactions require light and water, occur in the thylakoids, and produce ATP and NADPH. The light-independent reactions require carbon dioxide, occur in the stroma, and produce high-energy sugars.
