What are the three 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.
Which best lists the end products of the light?
The answer to this question is ATP and NADPH. Photosynthesis occurs in two stages: light-dependent reactions or light reactions capture the energy of light and use it to make the energy-storage molecules ATP and NADPH; and, the light-independent reactions use these products to capture and reduce carbon dioxide.
What are the products of a light Dependant reaction?
The products of the light-dependent reactions, ATP and NADPH, are both required for the endergonic (def) light-independent reactions. The light-dependent reactions involve two photosystems called Photosystem I and Photosystem II.
Is carbon dioxide a product of light-dependent reaction?
The light-dependent reactions release oxygen as a byproduct as water is broken apart. In the Calvin cycle, which takes place in the stroma, the chemical energy derived from the light-dependent reactions drives both the capture of carbon in carbon dioxide molecules and the subsequent assembly of sugar molecules.
What event occurs in photosystem II?
Photosystem II obtains replacement electrons from water molecules, resulting in their split into hydrogen ions (H+) and oxygen atoms. The oxygen atoms combine to form molecular oxygen (O2), which is released into the atmosphere. The hydrogen ions are released into the lumen.
Does photosystem 2 produce ATP?
Electrons are transferred sequentially between the two photosystems, with photosystem I acting to generate NADPH and photosystem II acting to generate ATP. Electron transport through photosystem II is thus coupled to establishment of a proton gradient, which drives the chemiosmotic synthesis of ATP.
What event occurs in photosystem?
The event that happens in photosystem I is that electrons are transferred to ferredoxin. This is a part of photosynthetic light reactions which makes use of light energy to transfer electrons from plastocyanin to ferredoxin.
Which event occurs in photosynthesis one?
Three major events occur in plant cells during photosynthesis: (1) absorption of light energy, (2) conversion of light energy into chemical energy, and (3) storage of chemical energy in sugars.
What event occurs in photosynthesis?
Answer Expert Verified The three events that occur during the process of photosynthesis are: (i) Absorption of light energy by chlorophyll. (ii) Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen. (iii) Reduction of carbon dioxide to carbohydrates.
How is ADP converted to ATP quizlet?
How is ADP converted to ATP? it is converted in a condensation reaction in which a phosphate molecule is added. this is done by creating the third and final bond of the ATP molecule as this bond has the most energy.
What process causes the formation of ATP quizlet?
During the process of photosynthesis, light penetrates the cell and passes into the chloroplast. The light energy is intercepted by chlorophyll molecules on the granal stacks. Some of the light energy is converted to chemical energy. During this process, a phosphate is added to a molecule to cause the formation of ATP.
