American chemist Dr. Daniel Nocera has devoted his career to finding this alternative energy source using photosynthesis as his inspiration. Photosynthesis‚ the conversion of solar energy into chemical energy stored in the bonds of glucose‚ is arguably one of the most important chemical reactions on earth. The maintenance of life on earth‚ our food‚ oxygen‚ and fossil fuels depend upon photosynthesis. In this process water and carbon dioxide are converted to oxygen and glucose using energy from the sun

captured. Colours add magnificence to a peacock’s features and excitement to hobbies like snorkeling and photography. The blue of the ocean and the sky would never be cherished without colours. Therefore‚ colour adds multifarious ness to nature. In fashion‚ if there were no colours‚ everything would only be patterns and designs. There would be no longer a wider range of choices when shopping. Everyone would be wearing similar types of shirts. Take for example‚ the make-up industry. Colours make nature

Living things get energy to do things through photosynthesis‚ food molecule breakdown‚ build up‚ storage‚ and lastly cellular respiration. All of these ideas are the reason that myself and others have energy to do anything and everything. Photosynthesis is one way plants(plants are the main source of energy for all things)get energy to do things. The reactants of this are water‚ carbon dioxide‚ and although light energy is not a reactant‚ it is necessary once the energy from the seed is gone. Carbon

of alertness (a CNS effect) but also a higher heart rate‚ blood pressure and respiratory rate. Caffeine also acts as a stimulant drug‚ causing increased amounts of stimulatory neurotransmitters to be released. At high levels of consumption caffeine has been linked to restlessness‚ insomnia and anxiety‚ causing raised stress and blood pressure. This can lead to heart and circulation problems. Hypothesis: Daphnia subjected to a caffeine solution will show a rise in heart rate as caffeine is a stimulant

INTRODUCTION Overall‚ light energy drives a flow of electrons along a system of carriers from H2O to NADP+. The carriers are bound to the membrane between reaction centres. Though their precise arrangement is not known‚ the carriers seem to be organized so that the electron flow cause H+ to move from the stroma to the space within the thylakoids. The resulting difference in H+ concentration across the membrane represents a store of energy that is though to drive he formation of ATP. According to

WHAT IS PHOTOSYNTHESIS? 3 Every day the total amount of energy that is captured through photosynthesis all across our planet is equal to approximately 135 terawatts. Now to put this number into perspective the entire human race consumes approximately 15 terawatts of energy daily. This means that there is 9 times more energy being absorbed every day through photosynthesis‚ as there is energy being consumed by all of mankind (Bridges 2008). In order to fully understand photosynthesis

The effect of different coloured lights on the rate of Photosynthesis Objective: To find out which colour of light provides the best consequences for the production of oxygen/ the rate of photosynthesis Background: In photosynthesis‚ there are two main parts‚ including light dependent and light-independent reactions. Plants use the energy from light for producing sugar‚ which is being converted into ATP by cellular respiration. They also are the only organisms that produce oxygen along with glucose

The Festival of Colours Holi is a popular‚ religious festival that is celebrated by Hindus. It is often referred to as the ‘festival of colours’ because of the famous ritual that it has bore. It originated in India and is celebrated near the end of the winter season‚ on the last day of the lunar month. This usually falls in late February‚ or early March. Holi is a celebration of various legends‚ such as the legend of Prahlad and Hiranyakshyap. It stated that there was once a demon king named

Elodea & Photosynthesis Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product. Introduction This lab has been created in order to find what extent does distance from a light source (5cm‚ 10cm‚ and 15cm) affect the rate of photosynthesis (measured in bubbles / 3 min) in Elodea water plants.

Abstract The following experiment details the effect of different concentrations of catalase on the production of oxygen and water through the breakdown of Hydrogen Peroxide. In this experiment paper disc where coated in varying concentrations of catalase‚ 0‚ 25‚ 50 75 and 100%. The time taken for the disc to float between two markers on the side of a glass was then recorded. This experiment demonstrates that the higher the concentration of enzyme used the greater the production of oxygen on the
