CO2 + Carbon dioxide + H2O Water ?^ CH2O + O2 ->- Formaldehyde + Oxygen. chromoplocsb This process is one of the early steps in photosynthesis (phos — light; sj/)i—together; tithemi — place: light places together). Photosynthesis is the combining of carbon dioxide and water by chlorophyll, in the presence of light, to make sugar. The molecule of formalde- hyde is then chemically joined with other molecules of formal- dehyde to make a simple sugar. Further combining will build up more and more complex sugars such as monosaccharides, di- saccharides, polysaccharides (starch is in this group). Some- times other complex compounds such as oils and fats are pro- duced. These are often found in cells as storage products. They are again converted into simpler forms of sugar when they are to be used as fuel. Sugar is also the basis for the formation of proteins. In order to manufacture protein — a process known as protein-.
