During the process of photolysis under light reaction the water molecule split up to release H + and OH – ions. The gas exchange that occurs when stomata are open facilitates photosynthesis. The Oxygen Released Into The Air As A Product Of Photosynthesis Comes From 2 Pts) A. Formation of NADPH (reduced Nicotinamide Adenine Dinucleotide Phosphate) How can Messenger RNA (mRNA) be best described. Another part of photosynthesis is that plants take in carbon dioxide, as well as water. Add your answer and earn points. Oxygen is a byproduct of photosynthesis. There are a lot of electrons that become lost or replaced during the photosystem II. In this transfer, the CO2 is “reduced,” or receives electrons, and the water becomes “oxidized,” or loses electrons. The light-harvesting complex (or antenna complex) is an array of protein and chlorophyll molecules embedded in the thylakoid membrane of plants, which transfer light energy to one chlorophyll a molecule at the reaction center of a photosystem. Photorespiration is a phenomenon that occurs in the cycle (a) Pyruvate (b) Glycolate (c) Hill (d) Krebs Answer: (b) Glycolate 2. • This procedure occurs during a light-dependent reaction. • The oxygen is discharged into the atmosphere during the light reactions. 4.6 billion years c. 1 billion years b. e. RuBP . Green pigments found in chloroplast, that absorb light during photosynthesis. The dark stage is where the plant absorbs air through the leaves, mixed with other organic compounds, and creates carbohydrates or sugars. The oxygen released during photosynthesis comes from thesplitting of waterduringthe light-dependent reaction. Carbon fixation involves the addition of carbon dioxide to _____. The oxygen comes from water. What is the antenna complex? The other 3 O2 molecules must come from CO2, right? • During photosynthesis, the plant absorbs carbon dioxide. The oxygen that was released during photosynthesis comes from water. Which organelle of the leaf reflects back excess light? Excess oxygen gathered after all these are released into the atmosphere during respiration. The electrons that are lost in the photosystem should always be replaced. There are a lot of people who do not realize just how important photosynthesis is when, in fact, this is the reason why we have enough oxygen in the air in order to supply us all. Whenever the process of splitting water happens, this is also the time when oxygen becomes released. What is the difference between Race and Culture? What is the reason for Okazaki fragments being formed during DNA replication? Where does the oxygen released during photosynthesis come from itachi79 is waiting for your help. Comments. The oxygen released during photosynthesis comes from the splitting of water molecules to provide the electrons with hydrogen and oxygen. This oxygen is released from the leaves, and this is made available for animals and microorganisms for their respiration. The electrons that are lost in the photosystem should always be replaced. In order to make photosynthesis work, plants need carbon dioxide that they usually get because humans release carbon dioxide whenever they breathe out. Being in the arts and science department amuses me every day. What causes leaves to change color in the autumn? What is NADPH? Photosynthesis is the process by which plants and other phototrophs convert carbon dioxide and water molecules into carbohydrates and waste oxygen using solar energy. If this theory is correct, then it follows that all of the oxygen released during photosynthesis comes from water just as all the sulfur produced by the purple sulfur bacteria comes from H2S. New questions in Biology. A is the answer to this question. Where does the oxygen released during photosynthesis come from 1. The process will ensure that the right nutrients will be received by the plant and the excess oxygen will then be released into the air. The correct answer to this question is A, Splitting of water molecules. They are then converted into oxygen and sugar. Photosystem I? Understand the purpose of the Calvin cycle and how it relates to photosynthesis. During this procedure, green plants use energy from solar radiation, Carbon Dioxide from the environment, water and minerals from obtained from soil to arrange their carbohydrate food and in turn develop oxygen. H 2 O 2H + + 1/2O 2 + 2e – It should be noted that oxygen released during photosynthesis comes from water. What is the difference between NPP and GPP? What happens when energy is absorbed by chlorophyll? Photosynthesis Multiple Choice Questions and Answers 1. After 3-PGA is phosphorylated, it is reduced by _____. The Chlorophyll in the leaves absorb sunlight and the water and carbon dioxide are used for making sugar. Can we harvest the sun's energy like plants? c. ATP - chemical energy that is stored as ATP. The oxygen is what we breathe in so that we can continue living. The sunlight is absorbed by Chlorophyll present, which is the green pigment present in leaves. During oxygenic photosynthesis, light energy transfers electrons from water (H2O) to carbon dioxide (CO2), to produce carbohydrates. a. water b. sugar c. pigments d. carbon dioxide 32.
