model ideas
energy from food
new model ideas
living things rearrange food (specifically glucose - $\ce{c6h12o6}$) and $\ce{o2}$ into $\ce{co2}$ and $\ce{h2o}$.
($\ce{c6h12o6 + o2}$) have higher energy than ($\ce{co2 + h2o}$) so this rearrangement releases energy.

• the rearrangements occur in a series of steps rather than all at once.
• collectively the reactions are called cellular respiration.
• usable cellular energy is released in the form of atp.

matter from food
some of this matter is really taken in for energy. it is rearranged to obtain energy in a reaction called cellular respiration. the products are expelled from the body as carbon dioxide and water ($\ce{co2 + h2o}$).

• some of the matter we take in is used to build proteins, fats and complex carbs that form body structures.
• excess food not used for energy or building materials is converted to fat and stored.

what is the overall reason for cellular respiration? why do we do it?
which of the above energy diagrams above is similar to cellular respiration?
which of the above energy diagrams is similar to photosynthesis?
which of the above energy diagrams is similar to burning ethanol?
define atp.
what is the purpose of atp?

Explanation:

The question "Define ATP" falls under Biology (a subfield of Natural Science). ATP, or Adenosine Triphosphate, is a molecule that carries energy within cells. It is often referred to as the "energy currency" of the cell because it stores and transfers energy for cellular processes. Its structure consists of an adenine base, a ribose sugar, and three phosphate groups, and the breaking of the bond between the second and third phosphate groups releases energy that cells can use for various functions like metabolism, movement, and active transport.

Answer:

ATP (Adenosine Triphosphate) is a molecule that serves as the primary energy carrier in cells, storing and transferring energy for various cellular processes. It consists of an adenine base, a ribose sugar, and three phosphate groups, and energy is released when the bond between the second and third phosphate groups is broken.
