What are the 7 steps of light-dependent reactions?
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 is the correct order of the reactions in the light reactions?
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. You just studied 33 terms!
What are the process of light-dependent reaction?
The light-dependent reactions convert light energy into chemical energy. The goal of the light-dependent reactions of photosynthesis is to collect energy from the sun and break down water molecules to produce ATP and NADPH. Each water molecule breaks down into two hydrogen (H) atoms and one oxygen (O) atom.
What is the sequence of flow of electrons during the light-dependent reactions?
(a) The correct sequence of flow of electrons in the light reaction is PSII, plastoquinone, cytochromes, PSI and ferredoxin.
Where do light-dependent reactions occur?
Light-dependent reactions happen in the thylakoid membrane of the chloroplasts and occur in the presence of sunlight. The sunlight is converted to chemical energy during these reactions. The chlorophyll in the plants absorb sunlight and transfers to the photosystem which are responsible for photosynthesis.
What is the correct order of the steps of the Calvin cycle?
The Calvin cycle has four main steps: carbon fixation, reduction phase, carbohydrate formation, and regeneration phase.
Which step in the process of photosynthesis is dependent on light energy?
The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.
What is the order of flow of electrons in the light-dependent reactions of photosynthesis?
Which of the following is the correct order of electron flow in the light reactions of photosynthesis? Electrons flow through the components of the linear electron pathway from water to NADPH. When a pigment molecule in a light-harvesting complex absorbs a photon of light, what happens to its excited-state electron?
What is the correct sequence of power flow?
Hydropower Plant: It is the correct Sequence of the reservoir, penstock, Surge, tank,& turbine the surge tank is open to the atmosphere and connected to penstock.
What are the 4 steps of the Calvin cycle?
The Calvin cycle has four main steps: carbon fixation, reduction phase, carbohydrate formation, and regeneration phase. Energy to fuel chemical reactions in this sugar-generating process is provided by ATP and NADPH, chemical compounds which contain the energy plants have captured from sunlight.
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 examples of light dependent reactions?
One very good example of Light Dependent Reaction is Photosynthesis and the product of the primary step of Photosynthesis is Oxygen, NADPH and ATP .
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.
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 . [ ]
