What are the steps of light-dependent reactions of photosynthesis?
Here are the basic steps:
- Light absorption in PSII. When light is absorbed by one of the many pigments in photosystem II, energy is passed inward from pigment to pigment until it reaches the reaction center.
- ATP synthesis.
- Light absorption in PSI.
- NADPH formation.
What are the products of light-dependent reactions of photosynthesis?
The exergonic light-dependent reactions of photosynthesis convert light energy into chemical energy, producing ATP and NADPH. These reactions occur in the thylakoids of the chloroplasts. The products of the light-dependent reactions, ATP and NADPH, are both required for the endergonic light-independent reactions.
What are the 6 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 are the products of the light-dependent reactions of photosynthesis quizlet?
The products of light-dependent pathways of photosynthesis are Oxygen, ATP, and NADPH. The reactants of light-independent reactions are ATP, NADPH, and Carbon Dioxide.
What are the 7 steps of light-independent reactions?

| What are the three parts of the light-dependent reactions? | Photosystem 2, Photosystem 1, and ATP Synthase |
|---|---|
| What are the functions of photosynthesis 1? | to absorb and transfer energy when it goes into the electron transport chain. also to break down water as it goes across the thylakoid membrane. |
In what way are the light-dependent and light?
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. These two energy-storing molecules are then used in the light-independent reactions.
What are the 3 reactants of light-dependent reactions?
The reactants in the light-dependent chemical reaction are adenosine diphosphate (ADP), oxydized nicotinamide adenine dinucleotide phosphate (NADP+) and the hydrogen in water.
What is light-dependent in photosynthesis?
What is the difference between light independent and dependent reactions?
The products of the light-dependent reactions, ATP and NADPH, have lifespans in the range of millionths of seconds, whereas the products of the light-independent reactions (carbohydrates and other forms of reduced carbon) can survive for hundreds of millions of years.
What is the equation for the light dependent reactions?
The light-dependent reactions convert light energy into chemical energy, producing ATP and NADPH. 5. The light-dependent reactions can be summarized as follows: 12 H2O + 12 NADP+ + 18 ADP + 18 Pi + light and chlorophyll yields 6 O2 + 12 NADPH + 18 ATP.
What do light dependent reactions generate?
The light-dependent reactions release oxygen as a byproduct as water is broken apart. In the Calvin cycle, which takes place in the stroma, the chemical energy derived from the light-dependent reactions drives both the capture of carbon in carbon dioxide molecules and the subsequent assembly of sugar molecules.
What is the definition of light dependent reactions?
Light-dependent reaction (biology definition): the series of biochemical reactions in photosynthesis requiring light energy that is captured by light-absorbing pigments (such as chlorophyll) to be converted into chemical energy (ATP and NADPH). What is the main purpose of the light-dependent reactions?
