What is the first product of Calvin cycle?
Carbon dioxide combines with ribulose‐1, 5‐biphosphate (RuBp) to produce a transient intermediate compound. The intermediate compound splits up immediately in the presence of water to form the two molecules of 3‐phosphoglycerate or 3‐PGA. It is the first stable product of photosynthesis.
How many ATP are produced in light reaction?
4. 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.
Does light dependent reaction produce oxygen?
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 comes first ps1 or ps2?
Though the two photosystems in the light-dependent reactions got their name in the series, they were discovered, but the photosystem II (PS II) comes first in the path in the electron flow and then the photosystem I (PSI).
How does light-dependent reactions produce ATP?
In the light-dependent reactions, energy absorbed by sunlight is stored by two types of energy-carrier molecules: ATP and NADPH. The energy generated by the hydrogen ion stream allows ATP synthase to attach a third phosphate to ADP, which forms a molecule of ATP in a process called photophosphorylation.
