The products of the light-dependent reactions,
ATP and NADPH
, are both required for the endergonic light-independent reactions. The light-dependent reactions involve two photosystems called Photosystem I and Photosystem II.
What are the three products of the light-dependent reactions quizlet?
The products of light-dependent pathways of photosynthesis are
Oxygen, ATP, and NADPH
.
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 is the end product of light-dependent reaction?
There are two end products of the light reaction of photosynthesis,
ATP and NADPH
. These molecules are produced during the cyclic and the non-cyclic photophosphorylation reactions.
What are the products of light-dependent reaction?
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.
What comes from the light-dependent reactions 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.
What are the products of light-dependent reactions Why are they important in light-independent?
The two products of the light-dependent reactions of photosystem are
ATP and NADPH
. The movement of high energy electrons releases the free energy that is needed to produce these molecules. The ATP and NADPH are used in the light-independent reactions to make sugar.
What is the first set of light-dependent reactions?
The overall function of light-dependent reactions, the first stage of
photosynthesis
, is to convert solar energy into chemical energy in the form of NADPH and ATP, which are used in light-independent reactions and fuel the assembly of sugar molecules.
Where do light dependent reactions occur?
Light-dependent reactions happen in
the thylakoid membrane of the chloroplasts
and occur in the presence of sunlight. The sunlight is converted to chemical energy during these reactions. The chlorophyll in the plants absorb sunlight and transfers to the photosystem which are responsible for photosynthesis.
What are the 7 steps of light dependent reactions?
- (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 is the main purpose of the light dependent reactions?
The light-dependent reactions
use light energy to make two molecules needed for the next stage of photosynthesis
: the energy storage molecule ATP and the reduced electron carrier NADPH. In plants, the light reactions take place in the thylakoid membranes of organelles called chloroplasts.
What is the end product of photolysis?
Photolysis of water observes
release of oxygen
, as a by-product, and release of hydrogen. During photosynthesis when chlorophyll is left by its electrons, the place where the electrons were is left with a hole, which is filled by oxidised water. When this oxidised water splits, it releases oxygen and hydrogen.
Is Glucose is the end product of light reaction?
Note: The ATP and NADPH from the light-dependent reactions are used to make sugars in the Calvin cycle. It takes place in the stroma. The Calvin cycle adds carbon to a simple five-carbon molecule known as RuBP.
The end product of Calvin cycle is glucose
.
What are the end products of light and dark reaction?
| Light Reaction Dark Reaction | ATP and NADPH are the end products of this reaction. The end products of light reaction, i.e. ATP and NADPH are used here to form glucose as the end product. | This reaction causes the water molecule to split into hydrogen and oxygen. There is no splitting of water. |

What is required for the light-dependent reactions quizlet?
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 are the three primary factors that affect the rate of photosynthesis?
What happens during photoionisation in the light-dependent reaction?
The light-dependent reaction in such detail as to show that:
chlorophyll absorbs light, leading to photoionisation of chlorophyll
.
some of the energy from electrons released during photoionisation is conserved in the production of ATP and reduced NADP
. … photolysis of water produces protons, electrons and oxygen.
