Formula for photosynthesis and respiration?[:
The formulas for photosynthesis and respiration are as follows:
Photosynthesis:
6CO2 + 6H2O + sunlight → C6H12O6 (glucose) + 6O2
In this process, carbon dioxide (CO2) and water (H2O) are converted into glucose (C6H12O6) and oxygen (O2) using sunlight as an energy source. This reaction occurs in the chloroplasts of plant cells.
Respiration:
C6H12O6 (glucose) + 6O2 → 6CO2 + 6H2O + energy (ATP)
Respiration is the process by which cells convert glucose and oxygen into carbon dioxide, water, and adenosine triphosphate (ATP) through a series of chemical reactions. This process occurs in the mitochondria of cells, including plant cells.
Now, let me explain how to derive these formulas step by step:
Photosynthesis:
1. During photosynthesis, plants absorb carbon dioxide (CO2) from the atmosphere through tiny openings called stomata present on their leaves.
2. They also absorb water (H2O) from the soil through their roots.
3. In the presence of sunlight, chlorophyll in the chloroplasts of plant cells captures the energy and converts it into chemical energy.
4. The carbon dioxide and water are then converted into glucose (C6H12O6) using the energy stored in ATP, created during the light-dependent reactions.
5. Oxygen (O2) is released back into the atmosphere as a byproduct of photosynthesis.
Respiration:
1. Glucose and oxygen in the form of C6H12O6 and 6O2 are obtained either from photosynthesis in plants or by consuming glucose-rich food in animals.
2. In the mitochondria, glucose and oxygen undergo a series of chemical reactions known as cellular respiration.
3. Through these reactions, glucose is gradually broken down, releasing energy in the form of ATP.
4. Carbon dioxide (CO2) and water (H2O) are byproducts of the cellular respiration process, and they are expelled from the organism.
So, the formulas for photosynthesis and respiration summarize the chemical changes occurring during these processes.
