What is the function of water in cellular respiration and photosynthesis? Detailed answer please
C6 H12 O6 + O2---> CO2+ 6H2O + energy (ATP) respiration
CO2+ H2O + sunlight energy---> C6 H12 O6+ O2, photosynthesis
hope this helps
btw: i already learn this in science
C6 H12 O6 + O2---> CO2+ H2O + energy (ATP) respiration
made a little mistake
can you explain this in words?

in photosynthesis water is useful for reduction reactions that's why oxygen is released and hydrogen is fixed in the form of carbohydrates and in case of respiration water is useful for oxidation of the photosynthesis end products i.e. Carbohydrates or glucose so hear energy is released among them some amount of energy is stored in the form of ATP which is useful for metabolic reactions and remaining is liberated in the form of heat
In both cellular respiration and photosynthesis, water plays a crucial role. Let's break it down for each process:
1. Cellular Respiration:
Cellular respiration is the process by which cells convert stored energy in organic molecules into usable energy in the form of ATP (adenosine triphosphate). Here's how water is involved:
a) Glycolysis: This is the initial step of cellular respiration, taking place in the cytoplasm. During glycolysis, glucose is broken down into pyruvate molecules. While no direct involvement of water occurs during this step, the presence of water is crucial for the efficient functioning of the enzymes involved.
b) Citric Acid Cycle (Krebs cycle): In this phase, which takes place in the mitochondria, the pyruvate molecules produced in glycolysis are further broken down into carbon dioxide. During this process, water is involved indirectly as an electron acceptor. NADH and FADH2 molecules are generated, which carry high-energy electrons. These electrons are then passed through a series of electron transport chain (ETC) proteins, and ultimately, oxygen molecules accept these electrons and combine with hydrogen ions to form water (H2O). This is known as the electron transport chain, the final stage of cellular respiration.
2. Photosynthesis:
Photosynthesis is the process by which plants, algae, and some bacteria convert sunlight energy into chemical energy in the form of glucose. Water has a direct and essential role in photosynthesis:
a) Light-dependent reactions: These reactions occur in the thylakoid membranes of the chloroplasts. During this process, water molecules are split through a process called photolysis. This splitting releases electrons, hydrogen ions, and oxygen molecules. The oxygen is released as an output, while the electrons and hydrogen ions are used in the electron transport chain to generate ATP (energy) and NADPH (electron carrier).
b) Calvin Cycle (Light-independent reactions): In this phase, which takes place in the stroma of the chloroplasts, carbon dioxide is converted into glucose using the energy from ATP and NADPH generated in the light-dependent reactions. Water indirectly participates again as it is required for the regeneration of the electron carrier molecule NADPH, which gets used up during the Calvin cycle.
Overall, water serves as a source of electrons, a medium for various enzymatic reactions, and a key component in the electron transport chain. Additionally, water molecules help maintain the structural integrity of cells and aid in the distribution of nutrients and waste products.
