Cellular Respiration |
Chemical process where mitochondria break down food molecules to produce ATP;Three stages are glycolosis,citric acid cycle and electron transport chain. |
|
|
Three stages of Cellular Respiration |
Glycolysis:anaerobic (no oxygen) Citric acid cycle and electron transport chain:aerobic(requires energy) |
|
|
Glycolosis |
Series of anaerobic chemical reactions in cytoplasm that breaks down glucose into pyruvic acid;forms a net profit of 2 ATP molecules |
|
|
Citric Acid Cycle |
Series if chemical reactions that breaks down glucose and produce ATP;energizes electron carriers that pass energized electrons on to the electron transport chain. |
|
|
Fermentation |
Two types: lactic acid and alcoholic Metabolic process that converts sugar to acids, gases or alcohol.Occurs in yeast and bacteria but also in oxygen-starved muscle cells |
|
|
Cell Respiration |
Process of fermentation,glycolysis,Citric acid (Krebs)Cycle,electron transport chain |
|
|
How do cells obtain energy from cellular respiration |
Glycolysis |
|
|
Structure of mitochondrion to events in cellular respiration |
Mitochondria breaks down food molecules to produce ATP (Cellular Respiration) |
|
|
ATP (Adenosine triphosphate) |
Energy-storing molecule in cells composed of an adenosine molecule,a ribose sugar and 3 phosphate groups;energy is stored in the molecule's chemical bonds and can be used quickly and easily by cells. |
|
|
ADP(Adenosine Diphisphate) |
Molecule formed from the breaking off of a phosphate group for ATP;Results in a large release of energy that is used for biological reactions |
|
|
Photosynthesis |
Process plants use to trap sun's energy and build carbohydrates, called glucose,that store energy. Equation:6CO2 + 6H2O + Sunlight -> C6H12O6 + 6O2 |
|
|
Light-Dependent and Independent Reactions |
Light-Dependent:Phase of photosynthesis where light energy is converted to chemical energy in form of ATP Light-Independent:Phase of photosynthesis where energy from light-dependent reactions is used to produce glucose and additional ATP molecules. |
|
|
Photosynthesis Vs. Cellular respiration |
Both:Use electron carriers and a cycle of chemical reactions to form ATP,Use electron transport chain to form ATP and to create a chemical and a concentration gradient of H+ within cell Photosynthesis:Produces high-energy carbohydrates and oxygen from sun's energy Cellular Respiration:Uses oxygen to break down carbohydrates to do ATP and compounds with a lower level of energy. |
