“The energy for life comes from the sun.” Outline the role of the photosynthesis process to explain what is meant by this statement. (3 marks) chlorophyll 6CO2(g) + 6H2O(l) + energy C6 H12 O6 (aq) + 6O2(g) 2830 kJ glucose Photosynthesis is the process in which plants use the sun’s light energy to convert carbon dioxide and water into carbohydrates such as glucose‚ sucrose‚ starch and cellulose. Carbohydrates are high energy compounds

Energy Transformation Conduction‚ convection‚ and radiation are things that exist in our life. Thanks to that stuff we have things like electricity and things to cook too. I am going to explain things about energy transformation. Heat transfer is the way heat moves through matter to change the temperature of other objects. There are three types of heat transfers‚ Conduction‚ Convection‚ and Radiation. The first kind of heat transfer‚ conduction‚ is heat transferring through direct contact of materials

on a body and displaces it in the direction of the force by one metre. Work done could be either positive or negative. When both the force and the displacement are in the same direction‚ positive work is done. When force acts in a direction opposite to the direction of displacement‚ the work done is negative. Summary LearnNext Video Table of Contents[Show] The energy of an object is its ability to do work. Energy is the cause and work is its effect. Therefore both work and energy have the

Energy Systems Our body needs a supply of energy to complete day to day tasks and to simply be able to move. We have more than one energy system‚ we have 3 in total and these are * ATP (anaerobic) * Lactic acid (anaerobic) * Aerobic (aerobic) All three off these energy systems are fuelled by the same chemical called ADP-PC. These systems produce this chemical at different speeds‚ for example the ATP system produces the chemical very fast as for the aerobic energy system produces it
