II. A erobic and Anaerobic Cellular Respiration
If oxygen is present, the next step is the Kreb’s cycle which takes place in the inner spaces of the mitochondria.
Pyruvic acid enters the Krebs cycle . It proceeds through the cycle and returns back to the starting point.
The end products of the Kreb’s cycle are 1 ATP, 1FADH 2 , and 3 NADH. However, there are 2 pyruvic acids (from glycolysis) therefore the cycle runs TWICE so the true end products for molecule of glucose is 2 ATP, 2 FADH 2 , and 6 NADH.
The sun is the primary source of energy for most all ecosystems.
All organisms on the planet can be divided into either autotrophs (organisms like plants that make their own food by converting sunlight energy into carbohydrates) or heterotrophs (organisms like animals that get their energy from consuming foods.)
IV. Cellular Respiration vs. Photosynthesis Cellular Respiration Photosynthesis Takes place in- All cells Cells with chlorophyll Occurs when- All of the time In the presence of light What goes in- Carbohydrates and oxygen Carbon dioxide and water What comes out- Carbon dioxide and water Carbohydrates and oxygen Energy source- Chemical bonds Light Result- Energy is stored as ATP Energy is stored as carbohydrates Processes -Glycolysis -Krebs Cycle -Electron Transport Chain -Light Dependent Reactions -Light Independent Reactions
