Imagine the future of energy. The future might look like a new power plant on the edge of town—an inconspicuous biore-actor that takes in yard waste and locally-grown crops like corn and wood chips and churns out electricity to area homes and businesses. Or the future may take the form of a stylish-looking car that refills its tank at hydrogen stations. Maybe …

Learn MoreOrganism Definition. An organism is a single individual, or being. While it may have many separate parts, the organism cannot survive without the parts, as the parts cannot survive without the organism. Some organisms are simple and only contain an information molecule describing how to obtain energy and reproduce the molecule.
Learn MoreOne of the main functions of the chloroplast is its role in photosynthesis, the process by which light is transformed into chemical energy, to subsequently produce food in the form of sugars. Water (H 2 O) and carbon dioxide (CO 2) are used in photosynthesis, and sugar and oxygen (O 2) is made, using light energy.
Learn MoreWhile carbohydrates supply immediate energy for the body, lipids — a class of macromolecule — provide long-term energy storage. Lipids, more commonly known as fats, appear in many foods. There are dozens of lipids, many of which are important for living things.

Learn MoreIt is important to understand how organisms acquire energy and how that energy is passed from one organism to another through food webs and their constituent food chains. Food webs illustrate how energy flows directionally through ecosystems, including how efficiently organisms acquire it, use it, and how much remains for use by other organisms of the …
Learn MoreFigure 1. In the carbon cycle, the reactions of photosynthesis and cellular respiration share reciprocal reactants and products. (credit: modification of work by Stuart Bassil) CO 2 is no more a form of waste produced by respiration than oxygen is a waste product of photosynthesis. Both are byproducts of reactions that move on to other reactions.
Learn MoreWhat''s found inside a cell. An organelle (think of it as a cell''s internal organ) is a membrane bound structure found within a cell. Just like cells have membranes to hold everything in, these mini-organs are also bound in a double layer of phospholipids to insulate their little compartments within the larger cells.
Learn MoreSo, normal fat reserves are a signal that metabolic processes are efficient and a person is healthy. Lipids are a family of organic compounds that are mostly insoluble in water. Composed of fats and oils, lipids are molecules that yield high energy and have a chemical composition mainly of carbon, hydrogen, and oxygen.
