How many ATP are produced in light-dependent reactions?

How many ATP are produced in light-dependent reactions?

The light-dependent reactions convert light energy into chemical energy, producing ATP and NADPH. 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 supplies the energy for ATP in the light-dependent reactions?

In the light-dependent reactions, energy absorbed by sunlight is stored by two types of energy-carrier molecules: ATP and NADPH. The energy that these molecules carry is stored in a bond that holds a single atom to the molecule. For ATP, it is a phosphate atom, and for NADPH, it is a hydrogen atom.

Is ATP a product of the light reactions of photosynthesis?

The light reactions capture energy from sunlight, which they change to chemical energy that is stored in molecules of NADPH and ATP. The light reactions also release oxygen gas as a waste product.

How many ATP and NADPH are produced in light dependent reaction?

The nine molecules of ATP and six molecules of NADPH come from the light reactions.

Is ATP a light dependent reaction?

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.

What is produced in light-dependent reactions?

ATP and NADPH produced by the light-dependent reactions of the photosystems are used by the Calvin cycle in the stroma of the chloroplast.

How is ATP produced in the light reactions?

In a process called non-cyclic photophosphorylation (the “standard” form of the light-dependent reactions), electrons are removed from water and passed through PSII and PSI before ending up in NADPH. This process requires light to be absorbed twice, once in each photosystem, and it makes ATP .

What does the ATP produced during the light-independent 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. These two energy-storing molecules are then used in the light-independent reactions….

Goal Convert light energy into chemical energy
Output NADPH, ATP, O2
