Transcript of PHOTOSYNTHESIS
Photosynthesis Chemical Reaction:
In words, this equation states that sunlight, combined with six molecules of water (H2O) and six molecules of carbon dioxide (CO2), produces one molecule of sugar (C6H12O6) and six molecules of oxygen gas (O2).
What it is?
A chemical process by which green plants convert sunlight into sugar. This process transforms a wave of light energy into chemical potential energy, which the plant then stores in the molecular bonds of sugar molecules.
Here are steps to walk you through the photosynthesis process that occurs each time the sun’s light reaches the leaves of a plant
The plant uses the stored chemical energy of ATP which stands for adenosine triphosphate, which is a chemical used throughout the body to transfer and hold energy
Which makes glucose from carbon dioxide.
The plant then uses the glucose to make even larger compounds of cellulose and starch, which store energy.
As the plant binds molecules into larger and larger chains, it captures and stores energy in the bonds to be released later. The plant uses the largest molecules to construct cell walls as the plant grows larger.
Cellular Respiration is photosynthesis in reverse, as you can see in this equation:
Outside pools need to be treated with Zeolite and Flocculant solution
All top soil must be removed
Buildings need to be high pressure
Inside the chloroplast (a special organelle within a plant cell), a molecule of chlorophyll absorbs the light.
The chlorophyll compound also gives the plant its green color.
A sequence of chemical reactions transfers the sun’s light energy into the chemical bonds that hold together special, energy-carrying molecules (the most common of which are called ATP).
At this point, the energy originating from the sunlight is being stored in the ATP molecules as chemical potential energy.
Sunlight + 6H2O + 6CO2 --> C6H12O6 + 6O2
C6H12O6 + 6O2 --> 6H2O + 6CO2+ energy
Respiration consists of a complicated series of chemical reactions. In the first stage, glucose is oxidized, and the chemical potential energy of its bonds is transferred to the chemical potential bonds of an ATP molecule. The ATP molecule can then be transported throughout the cell where its stored energy is used to complete various tasks within the cell. This process releases carbon dioxide gas and water.
Respiration occurs in your cells and is fueled by the oxygen you inhale. The carbon dioxide gas you exhale is the result of a completed cycle of cellular respiration.
Only plants can photosynthesize, but both plants and animals depend on respiration to release the chemical potential energy originally captured through photosynthesis.
Figure illustrates how closely photosynthesis and respiration are linked. As you can see, thanks to these two life-sustaining processes, plants and animals depend on each other to survive.
Photosynthesis is a need in everyday life
