What are the 3 products of the light-dependent reactions?
Glucose, ATP and O2
What are the products of the light-dependent reactions?
Explanation: The light dependent reaction converts solar energy to chemical energy, using the photosystem to capture light energy, and ultimately produce ATP and NADPH.
What are the products of the light-dependent reactions of photosynthesis 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.
Is oxygen a product of light-dependent reactions?
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 products of the light-dependent reactions are used in the light-independent reactions?
Figure 8.6. 1: The light-dependent reactions of photosynthesis (left) convert light energy into chemical energy, forming ATP and NADPH. These products are used by the light-independent reactions to fix CO2, producing organic carbon molecules.
Which of the following are three products of light-dependent reactions of photosynthesis?
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 2 products of the light reactions are used up in the Calvin cycle?
What two products of the light reactions are used up in the calvin cycle? NADPH, which is an electron carrier and can be reused, and ATP, or ADP, which is an energy molecule that can be rebuilt in another light reaction.
Is sugar a product of light-dependent reactions?
The ATP and NADPH from the light-dependent reactions are used to make sugars in the next stage of photosynthesis, the Calvin cycle. In another form of the light reactions, called cyclic photophosphorylation, electrons follow a different, circular path and only ATP (no NADPH) is produced.
Is glucose a product of light-dependent reactions?
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….
| Goal | Use stored chemical energy to “fix” CO2 and create a product that can be converted into glucose |
|---|---|
| Location | Chloroplasts—stroma |
| Input | CO2, NADPH, ATP |
What are the products of light-independent reaction used to power the light-independent reaction?
The light-independent reactions of photosynthesis take place within the stroma. It contains enzymes that work with ATP and NADPH to “fix” carbon from carbon dioxide into molecules that can be used to build glucose….
| Goal | Convert light energy into chemical energy |
|---|---|
| Output | NADPH, ATP, O2 |
What are the products of the light-dependent reactions Why are they important in light-independent reactions?
The light-dependent reactions produce ATP and either NADPH or NADH to temporarily store energy. These energy carriers are used in the light-independent reactions to drive the energetically unfavorable process of “fixing” inorganic CO2 in an organic form, sugar.
How are light dependent and light independent reactions related?
2. 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.
How are light independent reactions used in the Calvin cycle?
The light-independent reactions (Calvin cycle) use stored chemical energy from the light-dependent reactions to “fix” CO 2 and create a product that can be converted into glucose. The ultimate goal of the light-independent reactions (or Calvin cycle) is to assemble a molecule of glucose.
How does NADPH work in the light dependent reaction?
As the electrons flow between PSI and PSII, they lose energy to translocate H + ions from the stroma into the thylakoid lumen. Since they have lost energy before arriving at PSI, the electrons are re-energized at PSI to synthesize the reducing agent, called NADPH.
What happens in the light dependent phase of photosynthesis?
Photosynthesis occurs in two phases: 1) in the presence of light, called light-dependent reaction, and 2) in the absence of light, called light-independent reaction or dark reaction, also known as the Calvin cycle. The light energy is trapped by a pigment in the chloroplast and converted into chemical energy.
