Summary: Respiration deficiencies in mitochondria also called the cells powerhouses, are related with changed social behavior and spatial memory in laboratory mice. Since the brain's normal functioning depends on a large amount of the ATP energy that mitochondria get from food through aerobic respiration and decreased ATP could affect behavior.

Questions:
What is the chemical equation for cellular respiration? C6H12O6 + 6O2 ----> 6CO2 + 6H2O
What organelles are involved in this process? mitochondria
List three things you learned from this article in your own words. Social behavoir changes. Decreased amounts of ATP could have affected the mice's behavoir. The mice looked healthy and didnt have any other signs of bad mitochondrial disease.
What impact would the absence of this process have on the biosphere? not sure...

Cellular Respiration

Link-http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/C/CellularRespiration.html

Summary- Cellular respiration is the process of oxidizing food molecules, like glucose, to carbon dioxide and water. The energy released is trapped in the form of ATP for use by all the energy-consuming activities of the cell.The process occurs in two phases:
glycolysis, the breakdown of glucose to pyruvic acid
the complete oxidation of pyruvic acid to carbon dioxide and water

Questions- What is the chemical equation for cellular respiration? C6H12O6 + 6O2 --> 6CO2 + 6H2O + energy
What organelles are involved in this process?
Some biochemical pathways that produce very little ATP occur in the cytoplasm
Other pathways that produce a great deal of ATP occur in the mitochondrion
List three things you learned from this article in your own words. mitochondrion has much to do with cellular respiration, makes energy for cell, cytoplasm also makes ATP
What impact would the absence of this process have on the biosphere?
