Cellular Respiration Cellular respiration can be described as a chemical process that breaks bonds in food molecules or transforms chemical energy from organic molecules into ATP. - Only 40% of food energy is extracted and used for cellular work where the other 60% leaves in the form of heat energy ATP= Provides chemical energy for cellular work/processes in the cell. Structure= Composed of complex organic molecule called adenosine with a tail of three phosphate groups and a ribose sugar- pentose (ADP+P=ATP) (ADP is a diphosphate with an adenosine) ATP is recycled from ADP and phosphate through cellular respiration, ADP and P are connected to create ATP to be used for cell processes, ATP is used for cellular work and ADP and P are extracted from food molecules to create ATP again.

Cellular Respiration Plant cells harvest energy from the sun, and store it as glucose. That glucose must be transformed into energy the cell can use, specifically ATP. This takes place in the mitochondria of cells. There are two ways that a cell can harvest energy from the food (glucose) it takes in: Anaerobic Cell Respiration (Fermentation) ? glucose metabolism in the absence of oxygen that produces 2ATP molecules and either ethanol or lactic acid. Involves 2 stages: Glycolysis Fermentation Aerobic Cellular Respiration ? glucose metabolism with oxygen that produces 36 ATP molecules, CO2 and H2O. Involves 4 stages: Glycolysis Pyruvate oxidation Krebs cycle Electron transport and chemiosmosis Stage 1 ? Glycolysis

Cellular Respiration?An Overview 1 Cellular Respiration?An Overview What are the phases of cellular respiration? Why? All cells need energy all the time, and their primary source of energy is ATP. The methods cells use to make ATP vary depending on the availability of oxygen and their biological make-up. In many cases the cells are in an oxygen-rich environment. For example, as you sit and read this sentence, you are breathing in oxygen, which is then carried throughout your body by red blood cells. But, some cells grow in envi- ronments without oxygen (yeast in wine-making or the bacteria that cause botulism in canned food), and occasionally animal cells must function without sufficient oxygen (as in running sprints). In this
