Quick Answer: What Role Does Water Play In Photosynthesis Quizlet?
What role does water play in photosynthesis? Water provides the electrons and hydrogen ions needed to power the light-dependent and light-independent phases of photosynthesis.
What role does water play in photosynthesis?
Water is one of the reactants in photosynthesis, it provides the hydrogen needed to form glucose (a hydrocarbon). Water and carbon dioxide enter the leaf through the stomata (small holes on the underside of the leaf that are controlled by gaurd cells) by diffusion.
How is water used in photosynthesis quizlet?
The role of water in photosynthesis is to: provide electrons. The energy of the movement of electrons down a concentration gradient via electron transport within the thylakoid membrane is used to generate: ATP.
What role does water play in photosynthesis and cellular respiration?
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
Which of the following best describes the role of water in photosynthesis *?
Which of the following best describes the role of water in photosynthesis? Water molecules donate electrons to the electron transport chain.
What is the role of water in photosynthesis Class 10?
During the process of photosynthesis, six molecules of carbon dioxide and six molecules of water react in the presence of sunlight to form one glucose molecule and six molecules of oxygen. The role of water is to release oxygen (O) from the water molecule into the atmosphere in the form of oxygen gas (O2).
What role does water play in the light-dependent reactions of photosynthesis?
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 role does water play in respiration?
Water-based solutions like blood help carry molecules to the necessary locations. Thus, water’s role as a solvent facilitates the transport of molecules like oxygen for respiration and has a major impact on the ability of drugs to reach their targets in the body.
What is the role of water in the light reactions?
In the process of photosynthesis, water provides the electron that binds the hydrogen atom (of a water molecule) to the carbon (of carbon dioxide) to give sugar (glucose). Water acts as a reducing agent by providing H+ ions that convert NADP to NADPH.
What role does water play in the electron transport chain?
The electron transport chain is the third and final step of cellular respiration. Toward the end of the electron transport chain, the hydrogen from the coenzymes meets the oxygen that the cell has consumed and reacts with it to form water. In this way, water is created as a byproduct of the metabolism reaction.
Is water needed for photosynthesis?
To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. for photosynthesis. Plants also require water to make their food.
Is water a reactant in photosynthesis?
The reactants of photosynthesis are carbon dioxide and water.
Which of the following best describes the role of water in the reaction?
Which of the following best describes the role of water in the reaction? Water is a product that forms as a result of a dehydration synthesis reaction between the two amino acid monomers. This reaction also forms a covalent bond that connects the two amino acids together, forming a dipeptide. You just studied 12 terms!
How do plants use water for photosynthesis?
Photosynthesis is what plants do to create their food, and water is critical to this process. Water enters a plant’s stem and travels up to its leaves, which is where photosynthesis actually takes place. Once in the leaves water evaporates, as the plant exchanges water for carbon dioxide.
