All living things require the input of energy to exist – this energy is used to drive the thousands of biochemical reactions that occur to allow the organism to grow‚ reproduce and sustain life. This energy comes almost always from the Sun‚ in the rst instance – energy from sunlight is captured by photosynthetic organisms (e.g. plants‚ algae‚ certain bacteria) and converted into carbohydrates. These are then broken down by a process called cellular respiration‚ to produce energy-rich molecules (e

Proteins are polymers of amino acids. Long amino acid chains are folded into complex shapes‚ the shape of each determining the function of the protein. They are complex organic compounds‚ essential to the functioning as well as the structure of all organic cells. Proteins range in size from a few amino acids to thousands‚ having
