The exergonic light-dependent reactions of photosynthesis convert light energy into chemical energy, producing
ATP and NADPH
. These reactions occur in the thylakoids of the chloroplasts. The products of the light-dependent reactions, ATP and NADPH, are both required for the endergonic light-independent reactions.
What are the three products of the light-dependent reactions quizlet?
The products of light-dependent pathways of photosynthesis are
Oxygen, ATP, and NADPH
.
What are the products of a 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.
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
.
Is oxygen a product of light reaction?
Essentially, oxygen is
a waste product of the light reactions of photosynthesis
. It is a ”leftover” from a necessary part of the process. All the oxygen that is necessary to maintain most forms of life just happens to come about during this process.
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 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.
What are the two products of the light-dependent reactions quizlet?
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.
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 are light reactions?
The series
of biochemical reactions in photosynthesis
that require light energy that is captured by light-absorbing pigments (such as chlorophyll) to be converted into chemical energy in the form of ATP and NADPH. Synonym: light-dependent reaction.
What is the oxygen of light reaction?
The light reaction takes place in the thylakoid discs. There, water (H
2
0) is oxidized, and
oxygen (O
2
)
is released. The electrons freed up from water are transfered to ATP and NADPH. The dark reaction occurs outside of the thylakoids.
What are the end products of light reaction?
- Hint: The process of using the energy in sunlight to make food (glucose) is known as photosynthesis. …
- Complete answer: …
- Therefore, the end products are ATP and NADPH.
- Note: The ATP and NADPH from the light-dependent reactions are used to make sugars in the Calvin cycle.
What is the product of light reaction?
Thus the correct answer is (A)
NADPH and ATP
are the products of light reaction.
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?
Where does the light-dependent reaction occur quizlet?
In photosynthesis, the light-dependent reactions take place on
the thylakoid membranes
. The inside of the thylakoid membrane is called the lumen, and outside the thylakoid membrane is the stroma, where the light-independent reactions take place.
