Which is the site of the light dependent reactions of photosynthesis quizlet?
Summarize, in one sentence, what happens during the light dependent reactions of photosynthesis . The light dependent reactions occur in the thylakoid membrane, take light and water to make oxygen, which is released through the stomata leaves to make ATP and NADPH.
Which is the site of the light dependent reactions of photosynthesis mitochondria?
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 .
What is the site of light phase of photosynthesis?
The light phase is the first phase of photosynthesis . Light is absorbed by complexes made up of chlorophylls and proteins called photosystems, which are located in the chloroplasts.
What are the 3 products of the light dependent reactions?
The products of the light-dependent reactions, ATP and NADPH , have lifespans in the range of millionths of seconds, whereas the products of the light-independent reactions (carbohydrates and other forms of reduced carbon) can survive for hundreds of millions of years.
What is the product of the light dependent reaction?
4. The light-dependent reactions convert light energy into chemical energy, producing ATP and NADPH.
What are the 7 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 .
Which outcome is the main function of the light dependent reactions of photosynthesis?
The overall purpose of the light – dependent reactions is to convert light energy into chemical energy. This chemical energy will be used by the Calvin cycle to fuel the assembly of sugar molecules. The light – dependent reactions begin in a grouping of pigment molecules and proteins called a photosystem.
Which compound is a metabolic intermediate of the light independent reactions in photosynthesis?
Explanation; -The compound that is a metabolic intermediate of the light-independent reactions in photosynthesis is 3-PGA . -The light-independent reactions, or dark reactions, of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose .
Where do light reactions produce ATP?
ATP is produced on the stromal side of the thylakoid membrane, so it is released into the stroma. The electron arrives at photosystem I and joins the P700 special pair of chlorophylls in the reaction center.
What are the end products of light reaction?
The end products of the light reaction are ATP and NADPH , also known as assimilatory powers.
What is the difference between light dependent and independent reactions?
In the light – dependent reactions , energy from sunlight is absorbed by chlorophyll and that energy is converted into stored chemical energy. In the light – independent reactions , the chemical energy harvested during the light – dependent reactions drives the assembly of sugar molecules from carbon dioxide.
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 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 another name for the light independent reactions?
Other names for light-independent reactions include the Calvin cycle , the Calvin-Benson cycle , and dark reactions.
