Energy in biological system
ATP: The Perfect Energy
.A system is an organized group of interacting parts. A cell is a system of chemicals and processes. A body system includes organs that interact. An ecosystem includes living and nonliving things that interact. Biologists study many different systems. Structure and function are related in biology. Structure determines function.

Eat (food, nutrient)-energy source, building blocks, chemical energy/heat: so that you can grow, again uses combustion engine analogy to talk about making and converting energy and the byproducts of that process (in biological processes what gets burned up is chemical energy not heat energy)

Changes of energy and matter in a system can be described in terms of energy and matter flows into, out of, and within that system. (HS-LS1-1) Energy drives the cycling of matter within and between systems. (HS-LS2-3) Energy cannot be created or destroyed—it only moves between one place and another place, between objects and/or fields, or ...

Energy - Wikipedia
A chemical reaction releases energy when the bonds that are formed are more stable than the bonds that are broken. Because energy can only be released when molecules react to form other molecules, it is more accurate to think of energy as stored in a system (e.g. a system of reactants), rather than in individual molecules or bonds.

The energy in the cell exists as chemical energy. A source of this energy is a compound known as adenosine triphosphate (ATP). ATP when changed to a compound called adenosine diphosphate (ADP) releases energy for biological work in a cell. ADP can be changed to …

The energy level it carries is just the right amount for most biological reactions. Nutrients contain energy in low-energy covalent bonds which are not very useful to do most of kinds of work in the cells. These low energy bonds must be translated to high energy bonds, and this is a role of ATP.

Carbohydrates Serve as the primary source of energy for biological work. The muscular system and the brain rely almost solely on carbohydrates. There is a limit to how much carbohydrate (in the form of glycogen) you can store in your body. Excess carbohydrates are stored as fat. Lipids (Fats & oils) Provide the most energy-rich chemical bonds ...

Within a natural system, the transfer of energy drives the motion and/or cycling of matter. Students who understand the concepts are able to: Construct a scientific explanation for the role of photosynthesis in the cycling of matter and flow of energy into and out of organisms based on valid and reliable evidence obtained from sources ...
