Explanation: Water is one of the reactants in photosynthesis, it provides the hydrogen needed to form glucose (a hydrocarbon). carbon dioxide+water +energy → glucose + oxygen. 6CO2 +6H2O → C6H12O6 + 6O2. Water and carbon dioxide enter the leaf through the stomata (small holes on the underside of the leaf that are controlled by gaurd cells ...
Light provides energy for the synthesis of glucose from carbon dioxide and water during photosynthesis. Photosynthesis is a photo-chemical reaction involving 2 main steps, i.e. Light reaction or Hill’s reaction and Dark reaction or Blackmann’s reaction. Light reaction occurs in presence of light. Dark reaction can occur in absence of light ...
This is why the energy coming from sun in the form of photons is first turned into ATP, the energy of which is later used to make the bonds in the glucose molecule. To make glucose, the plant needs to make bonds between the carbon, hydrogen and oxygen atoms, which in turn come from CO2 and water. Sunlight cannot be used directly by plant to ...
In order for plants to carry out the process of photosynthesis, they need water, carbon dioxide and light. The water and carbon dioxide are the reactants - materials present before the chemical change. During the light reaction, chlorophyll molecules absorb light energy which is used to split water. This produces oxygen gas and hydrogen ions.
Explanation: Plants and trees use photosynthesis to use carbon dioxide in the air,water and sunlight to produce glucose and oxygen.Equation for photosynthesis: Carbon dioxide + water + light energy = glucose + oxygen. Respiration is process of breaking down to give off energy. It is used by animals.Plants also respire but only there is a lack ...
The thylakoids are the site of the light dependent reactions of photosynthesis. The thylakoids themselves contain the chlorophyll, but the thylakoid membrane is where the light reactions take place. These reactions include light driven water oxidation and oxygen evolution, the pumping of protons across the thylakoid membranes coupled with the ...
Explanation: Water, along with carbon dioxide, is involved in photosynthesis. Plants use this process to make foodstuff. It is the only mechanism we know of that can take carbon from the atmosphere and turn into a usable substance and eventually return it to the soil. Without plants our atmosphere would just be a reservoir of CO2 and life, as ...
Answer link. The elemental oxygen in water molecule combines with another oxygen from another water molecule to form oxygen molecule. The hydrogen will get combined with NADP+ to form NADPH and ultimately gets transported to the dark cycle. They are the supply of oxygen. This occurs in the chloroplast where there is a pigment called chlorophyll ...
Answer link. Enzymes of photosynthesis in presence of light energy builds larger molecule of glucose from Carbon dioxide and water molecule. Building a larger molecule from smaller molecules capture energy. Enzymes of photosynthesis capture energy of sun to build a larger molecule. This captured energy is used furthe by breaking down larger ...
Water is split during the light reaction to form oxygen (O_2) and Hydrogen ions (H^+). The light dependent reactions produce the oxygen that we breathe. The hydrogen ions formed are super important for photosynthesis. They will be used to create ATP molecules. The ATP molecules will be used later on in the dark reaction (also called the Calvin cycle). The ATP molecules allow the plant cell to ...
