objective SWBAT compare the reactants and products of cellular respiration in terms of energy and matter.

Question: What are the products and reactants of cellular respiration? Answer: The chemical reaction for cellular respiration is: C6H12O6 + 6O2 → 6CO2 + 6H2O (+36 ATP)

Expand Cellular respiration converts chemical energy into ATP: the energy-containing molecule that cells use to carry out life processes. Cellular respiration takes place in all eukaryotic cells. Molecules of glucose are broken down through glycolysis in the cytoplasm; and then to the mitochondria to the Krebs cycle and then electron transport chain. The chemical energy released from the bonds of glucose is used to synthesize ATP, and the remaining carbon and hydrogen atoms bind with oxygen to form carbon dioxide and water. The chemical reaction for cellular respiration is: C6H12O6 + 6O2 → 6CO2 + 6H2O (+36 ATP)

expand Cellular respiration starts with an initial requirement of 2 ATP molecules to start glycolysis and results in the production of 38 molecules of ATP, for a net gain of 36 ATPs. The reactants of cellular respiration are the products of photosynthesis; the reactants of photosynthesis are the products of cellular respiration. Aerobic (requires oxygen) and anerobic (does not require oxygen) respiration.

EXAMPLE DO NOT WRITE: What happens in the absence of oxygen? Glycolysis can still take place, producing pyruvic acid. In a low-oxygen environment, pyruvic acid can be turned into lactic acid as an alternate pathway for making small amounts of ATP.  For example, when a person exercises strenuously and the muscles' demand for oxygen exceeds the body's ability to deliver the oxygen, lactic acid is produced in the muscles as the body tries to keep up with ATP requirements. The burning sensation that is often felt in muscles that are exerted is caused by the presence of lactic acid.

heck Yes/heck no (Choral Responses) Cellular respiration converts glucose into ATP. The first, a process is known as glycolysis. After glycolysis is the next two steps: The Krebs cycle and The Electron Transport System. A total of 34-36 ATP are produced as a product of all of the steps.
