Energy in food
Perhaps our most immediate connection with energy is the energy in our food. Releasing the energy by burning gives an insight into the total energy available in a sample of foodstuff. Experiments

Energy
In this area you will find activities relating to photosynthesis and to cellular respiration, linked by the concept of energy transfer in living systems, and making connections between plants, animals and carbon dioxide in the atmosphere. Experiment...

Photosynthesis
Plants make their own food – absorbing and converting sunlight energy into chemical energy stored in carbohydrates such as glucose and other biomolecules. Photosynthesis is vital for the life of plants and for all animals on the planet. Explore the...

Enzyme-catalysed synthesis
pathway need not be the simple reversal of the catabolic pathway. The hydrolysis of the glucose-1-phosphate provides the energy necessary to synthesise the starch. The starch in potato tubers is stored inside cells in large granules which sediment on...
