Six molecules of carbon dioxide and six molecules of water are needed to produce one molecule of glucose. The first living cells probably evolved from these complex molecules (see life: Production of polymers). Water 3. The following 10 points summarize photosynthesis. 1. The Calvin cycle converts water molecules into oxygen gas as a byproduct of its reactions. 68. This oxygen is released into the atmosphere through the plant’s leaves. It represents stored energy that can be used by the plant, or consumed by other organisms. 6CO 2 + 6H 2 O + Light Energy → C 6 H 12 O 6 + 6O 2; Autotrophs store chemical energy in carbohydrate food molecules they build themselves. Comisión Municipal de Derechos Humanos de Bahía de Banderas, Nayarit. C) chemiosmosis. Little free glucose is produced in plants; instead, glucose units are linked to form starch or are joined with fructose, another sugar, to form sucrose (see carbohydrate). Light 4. Living organisms that are not plants depend on photosynthesis because photosynthesis produces organic molecules such as___ that can be used for nourishment and the___ gas that makes up large portion of the Earth's atmosphere. Cyanophytes are prokaryotic cells; that is, they contain no distinct membrane-enclosed subcellular particles (organelles), such as nuclei and chloroplasts. Speculation of why this is so ranges from random chance to the possibility that the radiation-absorbing properties of chlorophyll are adequate to provide for the energy needs of Earth's plants. All photosynthetic organisms (plants,certain protistans, prochlorobacteria, and cyanobacteria) havechlorophylla. There are a number of photosynthetic bacteria that are not oxygenic (e.g., the sulfur bacteria previously discussed). Glucose is a carbohydrate, a compound made of carbon, hydrogen and oxygen.

In photosynthesis, chlorophyll, water, and carbon dioxide are reactants. Heterotrophic organisms ranging from E. coli to humans rely on the chemical energy found mainly in carbohydrate molecules. Primitive coloured cells then had to evolve mechanisms for using the light energy absorbed by their pigments. As the light intensity increases to higher levels, however, the rate becomes saturated; light “saturation” is achieved at a specific light intensity, dependent on species and growing conditions. Both photosynthesis and cellular respiration occur in the chloroplasts of a cell. For example, the accidental joining (condensation) of the amino acid glycine and the fatty acid acetate may have formed complex organic molecules known as porphyrins. d.
