Because this process involves building bonds to synthesize a large molecule, it requires an input of energy (light) to proceed. When those energy demands increase, carbohydrates are broken down into constituent monosaccharides, which are then distributed to all the living cells of an organism. Methods/Strategies Used to Promote Active Learning Understanding energy phenomena is central to all fields of science. Biological processes are those processes that are vital for an organism to live, and that shape its capacities for interacting with its environment. Glucose (C 6 H 12 O 6) is a common example of the monosaccharides used for energy production. The potential energy stored in molecules can be converted to chemical energy, which can ultimately be converted to kinetic energy, enabling an organism to move. 0000039130 00000 n Catabolic pathways break down molecules and produce energy. 0000163960 00000 n The hummingbird obtains its energy from taking in food and transforming the nutrients into energy through a series of biochemical reactions. As chemical energy is released from the bonds in the monosaccharide, it is harnessed to synthesize high-energy adenosine triphosphate (ATP) molecules. One example of an anabolic pathway is the synthesis of sugar from CO2. 0000165198 00000 n Electromagnetic energy (or radiant energy) is energy from light or electromagnetic waves. Molecules can be modified and transported around the cell or may be distributed to the entire organism. 3. Organisms break down carbohydrates to produce energy for cellular processes, and photosynthetic plants produce carbohydrates. Plants store carbohydrates in long polysaccharides chains called starch, while animals store carbohydrates as the molecule glycogen.
