What are the main reactants (ingredients) required for photosynthesis? Photosynthesis helps in the conversion of water, CO2, and sunlight into glucose and oxygen. Photolysis is defined as the splitting of H2O molecule into hydrogen ions, electrons and oxygen in the presence of light and grana. water and carbon dioxide. pyruvate. What are the reactants of cellular respiration? So, the correct answer is 'oxygen'. If oxygen isn't released during photosynthesis, its counter process, cellular respiration, cannot occur, and there will be a lack of ATP generated and the plant will die. reverse of photosynthesis. They take in light energy from the sun and water and carbon dioxide from the air. This is then used to produce oxygen and glucose. The oxygen released during photosynthesis comes from the splitting of water molecules to provide the electrons with hydrogen and oxygen. Cellular respiration converts oxygen from the atmosphere and glucose from food into water and carbon dioxide. In oxygenic photosynthesis, H 2 O is split and supplies the electron to the reaction center. It is released during the photolysis of water which takes place during light reaction of photosynthesis. carbon dioxide.c. • This procedure occurs during a light-dependent reaction. (CO2) - The gas which is a byproduct of animal respiration that plants absorb during photosynthesis. (H2O) - The clear liquid which is the basis of living organisms, found in rivers, lakes, and oceans. oxygen. The plants use up glucose formed through photosynthesis as an energy source, and oxygen is released into the environment as a byproduct. sunlight. It is released as a waste product of photosynthesis. chlorophyll.d. Problem: The main byproduct of photosynthesis that is released into the environment is: a. glucose.b. • During photosynthesis, the plant absorbs carbon dioxide. At the end of glycolysis, glucose has been broken down into 2 molecules of. Because oxygen is generated as a byproduct and is released, this type of photosynthesis is referred to as oxygenic photosynthesis. • The oxygen is discharged into the atmosphere during the light reactions. The molecule consists of one central carbon atom and two oxygen molecules. This often considered a reversible reaction, as the reverse of this reaction (glucose and oxygen to water, carbon dioxide and … Photolysis of water is the main source of oxygen released during photosynthesis. oxygen is the byproduct of photosynthesis because from water (H2O), sunlight and carbon dioxide (CO2) , they release oxygen to make glucose. The gas released during the light reactions of photosynthesis is oxygen.The substrate of photosynthesis are carbon dioxide and water, and the products are glucose and oxygen. Oxygen is the byproduct of photosynthesis. Cellular respiration requires oxygen, and CO 2 is released as a byproduct. oxygen.e. This is how the plant generates energy, or ATP, to survive. Which is released as a byproduct of photosynthesis? All higher organisms (including plants and animals) respire. The oxygen byproduct of photosynthesis is utilized in another process in the plant: cellular respiration. During photosynthesis, oxygen is produced along with glucose (not a gas) Plants use photosynthesis as a way of producing glucose.
