Terms in this set (7)
- (1st Time) Energy is absorbed from the sun.
- Water is broken down.
- Hydrogen ions are transported across the thylakoid membrane.
- (2nd Time) Energy is absorbed from the sun.
- NADPH is produced from NADP+.
- Hydrogen ions diffuse through the protein channel.
- ADP becomes ATP.
What happens in the light-dependent reactions quizlet?
The light-dependent reactions produce oxygen gas and convert ADP and NADP+ into the carriers ATP and NADPH. ATP and NADPH provide the energy needed to build high-energy sugars from low-energy carbon dioxide.
What happens in the light-independent and dependent reaction?
In the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and that energy is converted into stored chemical energy. In the light-independent reactions, the chemical energy harvested during the light-dependent reactions drives the assembly of sugar molecules from carbon dioxide.
Which process occurs during the light-dependent reaction of photosynthesis?
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.
What happens in PSII?
PSII is the multisubunit chloroplast membrane-associated pigment–protein complex that uses the energy of sunlight to drive the oxidation of water, evolving oxygen, donating electrons into the photosynthetic electron transfer chain, and depositing protons into the thylakoid lumen.
What are the steps of light reactions?
Light reactions harness energy from the sun to produce chemical bonds, ATP, and NADPH. These energy-carrying molecules are made in the stroma where carbon fixation takes place. The light-independent reactions of the Calvin cycle can be organized into three basic stages: fixation, reduction, and regeneration.
What happens during the light dependent and 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.
What happens in the light reaction quizlet?
In the light reactions, pigment molecules in the thylakoids absorb light and convert it to chemical energy. The energy produced by light reactions is used to make 3-carbon sugars from carbon dioxide in a series of reactions known as the Calvin cycle.
What are the steps of light reaction?
Which of the processes occurs during the light reaction?
Photosynthesis begins with the light reactions. It is during these reactions that the energy from sunlight is absorbed by the pigment chlorophyll in the thylakoid membranes of the chloroplast. During the light reactions, water is used and oxygen is produced.
What are the major steps of light dependent reactions?
In light reaction of photosynthesis,a plant converts energy from one form to another from solar energy to potential energy to chemical energy.
What are the end products in light dependent reactions?
The end products of the light-dependent reactions that need the presence of light to occur are ATP and NADPH . [ ]
What is the end result of the light dependent reaction?
In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water. The light-dependent reactions release oxygen as a byproduct as water is broken apart.
What are the three products of the light dependent reactions?
The reaction products are glucose, ADP and NADP +. The latter two are used again in light-dependent reactions. While the Calvin cycle reactions can take place in the absence of light, they are in fact light dependent in plants and take place during the day.
