Essays on Light Energy

Introduction

Cellular respiration and photosynthesis are vital reactions in living organisms since without the two; there would be no life on earth. Cellular respiration involves a set of metabolic reactions that take place in cells of living organisms thereby converting nutrients like sugar into adenosine triphosphate (ATP) (Osterhoudt & Barhydt, 2010). On the other hand, photosynthesis involves the conversion of carbon dioxide into organic compounds by the photoautotroph in the presence of sunlight. Most animals attain their energy requirements through cellular respiration while on the other hand; photosynthesis is performed by most plants that can make their food. These two reactions ...

Introduction

Modern technological trends are moving towards the application of sustainable energy resources. Sustainable energy is that which is balanced on the lines of consumption and supply (Berndes, 2003). Concerning this, the utilization of such energy sources promotes the maintenance of controllable collateral implications. Sustainable energy leads to insignificant levels of environmental degradation. Additionally, the sustainability of energy resources can be understood according to their longevity. Such sources are deemed to fulfill the needs of the present while guaranteeing their progressive benefits into the future. Sustainable development has become a mainstream topic that is addressed in various forums globally. Hitherto, ...

Introduction

There are environmental chemical processes which require light to react. These processes are called photochemical reactions. Photochemical reaction is commonly initiated due to the absorption of solar energy or light. When molecules absorb energy in the form of light, the atoms are converted in a transient excited state (Larson & Weber, 1994). This transition state or excited has completely different physical and chemical properties with the initial state of the molecule. The excited states also have more tendencies to react since they are considered stronger acids and stronger reductants that the initial state of the molecule. The excited state of ...

Businesses relying on renewable energy sources to power their ventures as well as foster environmental sustainability have attracted the attention of environmentalist and activists. PepsiCo is one such company investing in various sustainable practices where they use light energy to power their water stewardship for factory use and community assistance (Environmental Sustainability, 2014). It reduces the emissions of the greenhouse gasses by finding alternative energy sources like electricity. The company boosts agriculture sector as one of its main sources of raw material by creating community outreach programs that foster best farming practices. PepsiCo has also invested heavily in reducing ...
