Cellular respiration occurs in most cells of both plants and animals

Cellular respiration is essential to the transfer of matter and energy through living systems. As living things use cellular respiration to transfer energy from food to ATP, some of the available energy in the food is transferred to the environment as heat, which travels through our atmosphere and goes back out to space. This energy transfer to heat occurs because cellular respiration isn’t 100 percent efficient at capturing the energy from food into ATP.

NAD+ and FAD act like electron shuttle buses for the cell. The empty buses, NAD+ and FAD, drive up to oxidation reactions and collect electron passengers. When the electrons get on the bus, the driver puts up the H sign to show that the bus is full. Then the full buses, NADH and FADH2, drive over to reactions that need electrons and let the passengers off. The buses are now empty again, so they drive back to another oxidation reaction to collect new passengers. During cellular respiration, the electron shuttle buses drive a loop between the reactions of glycolysis and the Krebs cycle (where they pick up passengers) to the electron transport chain (where they drop off passengers).

Cellular respiration is different from plain ol’ respiration

Biology Photosynthesis and cellular respiration are often described in two ways: (1) they are chemically opposite; and (2) they have a relationship to each other.

Cellular respiration is also important in the movement of matter through living systems: As living things break down food molecules using cellular respiration, they release the atoms from the food molecules back out into the environment as carbon dioxide and water. Photosynthesis brings in carbon dioxide and water from the environment, and cellular respiration sends them out again, forming a circular matter pathway that scientists call the carbon cycle.

After the large molecules in food are broken down into their smaller subunits during digestion, the small molecules can be further broken down to transfer their energy to ATP. During cellular respiration, enzymes slowly rearrange the atoms in food molecules. Each rearrangement produces a new molecule in the pathway and can also produce other useful molecules for the cell.

Fermentation is a "respiration" which does not use oxygen and which for thisreason is called anaerobic.


Monosaccharides or simple sugars such as glucose and fructose (C6H12O6) function as energy source in cells during cellular respiration and are also used to build cell structures and other organic molecules within the cells.
Disaccharides are composed of two monosaccharides joined together.

Respiration What is respiration

Three separate pathways combine to form the process of cellular respiration. The first two, glycolysis and the Krebs cycle, break down food molecules. The third pathway, oxidative phosphorylation, transfers the energy from the food molecules to ATP. Here are the basics of how cellular respiration works:

RESPIRATION - Science Clarified

Different kinds of food molecules enter cellular respiration at different points in the pathway. Cells break down simple sugars, such as glucose, in the first pathway — glycolysis. Cells use the second pathway, the Krebs cycle, for breaking down fatty acids and amino acids.

Oxygen discovery, atomic structure, and location information

These manufacturing processes, practiced by nearly every plant cell, greatly exceed the current capabilities of human technologies. The goals of the CLSF are to develop a detailed nano- to meso-scale understanding of plant cell walls, from glucose polymerization and glucan crystallization into cellulose microfibrils to the orderly hierarchical assembly of the components to form the mature plant cell wall. Success in our research goals will offer many lessons in how to create such hierarchical structures, how to vary and manipulate them, and potentially how to disassemble them more efficiently than is currently possible. Our team of accomplished biological, physical and computational researchers with their diverse technical expertise and team collaboration work towards these goals which straddle biology and physics.

The term respiration has two relatively distinct meanings in biology

At the end of the entire process of cellular respiration, the energy transferred from glucose is stored in 36 to 38 molecules of ATP, which are available to be used for cellular work. (And boy do they get used quickly!)
