What is the cycle of photosynthesis step by step?
The stages of photosynthesis
| Stage | Location | Events |
|---|---|---|
| Light-dependent reactions | Thylakoid membrane | Light energy is captured by chloroplasts and stored as ATP |
| Calvin cycle | Stroma | ATP is used to create sugars that the plant will use to grow and live |
Is PSII the Calvin cycle?
Therefore, it is likely that the activity of the Calvin cycle is involved in the susceptibility of PSII to photoinactivation. It has been assumed that when the Calvin cycle is interrupted, excess of absorbed light energy accelerates damage to PSII.
What are the 4 steps of photosynthesis in order?
The overall process of photosynthesis can be objectively divided into four steps/ process:
- Absorption of light. The first step in photosynthesis is the absorption of light by chlorophylls that are attached to the proteins in the thylakoids of chloroplasts.
- Electron Transfer.
- Generation of ATP.
- Carbon Fixation.
What is PSI and PSII?
Photosystem I (PSI) and Photosystem II (PSII) harvest light energy to drive photosynthesis. In plants these photosystems are composed of a core complex and a peripheral antenna system.
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.
Where does oxygenic photosynthesis occur?
cyanobacteria
Explanation: Oxygenic photosynthesis is a process of a non-cyclic photosynthetic electron chain where the initial electron donor is water and oxygen is a byproduct. It is found in cyanobacteria (Oscillatoria) and plants.
What are the 3 stages of Calvin cycle?
The Calvin cycle reactions (Figure 5.15) can be organized into three basic stages: fixation, reduction, and regeneration. In the stroma, in addition to CO2, two other chemicals are present to initiate the Calvin cycle: an enzyme abbreviated RuBisCO, and the molecule ribulose bisphosphate (RuBP).
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 type of reaction is 6CO2 6H2O C6H12O6 6O2?
The chemical equation for photosynthesis is 6CO2+6H2O→C6H12O6+6O2. 6CO2+6H2O→C6H12O6+6O2. In plants, the process of photosynthesis takes place in the mesophyll of the leaves, inside the chloroplasts.
When oxygen is released as a result of photosynthesis it is a direct by product of?
Transcribed image text: Question 12 When oxygen is released as a result of photosynthesis it is a direct by-product of chemlosmosis. splitting water molecules (oxidation of oxygen).
What are the 5 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.
