A similar set of proteins in the photosynthetic reaction center It is for all these commonalities the “endosymbiotic theory” had been proposed for the evolution of chloroplasts and mitochondria in the eukaryotic cells. According to the endosymbiotic theory, the early eukaryotic cells are believed to...
The release of chemical energy for use by cells. Once the energy that was in sunlight is changed into chemical energy by photosynthesis, an organism has to transform the chemical energy into a form that can be used by the organism. This process is cellular respiration. Describe Cellular Respir...
How does cellular respiration work? Plants can also break down sugars to produce energy, water and carbon dioxide. This process is called respiration and can happen both in darkness and in light. How does cellular respiration work? C6H12O6 + 6O2 + 6H2O ---> 12H2O + 6CO2 + ENERGY (Carbo...
Photosynthesis, respiration and carbohydrate content of the two types of cells were compared. Chlorophyll content and maximal rates of net photosynthesis were very similar in both cultures. High rates of photosynthesis were correlated with the exponential phase of growth and low cellular sucrose and ...
These molecules are similar to plastoquinone; they receive electrons from pheophytin and pass them to the intermediate electron carriers, which include the plastoquinone pool and the cytochromes b and f associated in a complex with an iron-sulfur protein. In light reaction I, electrons are ...
Many of the molecular details of this ATP-generating system are similar to those used by the mitochondrion in oxidative phosphorylation . (Phosphorylation refers to the addition of a phosphate group to adenosine diphosphate [ADP] to form ATP.) Like the mitochondrion, the chloroplast uses an ...

electron transport supporting RuBP regeneration could arise in species with low P status or with high leaf N:P ratios, for example on low P soils. Alternatively, if plants maintain a similar functional balance between components of the photosynthetic apparatus, irrespective of soil nutrient ...
