What Are The Two Main Sources Of Energy On Earth
You have two main sources of energy in your body
Tumour proliferation is promoted by an intratumoral metabolic symbiosis in which lactate from stromal cells fuels energy generation in the oxygenated domain of the tumour. Furthermore, empirical data show that tumour cells adopt an intermediate metabolic state between lactate respiration and glycolysis. This study models the metabolic symbiosis in the tumour through the formalism of evolutionary game theory. Our game model of metabolic symbiosis in cancer considers two types of tumour cells, hypoxic and oxygenated, while glucose and lactate are considered as the two main sources of energy within the tumour. The model confirms the presence of multiple intermediate stable states and hybrid energy strategies in the tumour. It predicts that nonlinear interaction between two subpopulations leads to tumour metabolic critical transitions and that tumours can obtain different intermediate states between glycolysis and respiration which can be regulated by the genomic mutation rate. The model can apply in the epithelial–stromal metabolic decoupling therapy.
There are two main sources of energy loss 1
The Earth has two main sources of energy, that from the Sun, and energy from within the Earth. This energy allows materials to move through the atmosphere, hydrosphere, lithosphere in interacting cycles. Earth's carbon, nitrogen, and oxygen cycles are dependent on temperature and biological conditions. For example, the oceans of the planet are a very large sink for carbon dioxide, and colder ocean temperatures mean more carbon dioxide is soluble in the oceans; some microbes "fix" nitrogen in, on, or near the roots of plants, meaning they transform unusable atmospheric nitrogen into forms that plants may use, therefore introducing it into other reservoirs of the nitrogen cycle.
