State the word equation for photosynthesis as: carbon dioxide + water → glucose + oxygen in the presence of light and chlorophyll

Describe photosynthesis as the process by which plants synthesise carbohydrates from raw materials using energy from light

Explain the effect of changes in pH on enzyme activity in terms of shape and fit and denaturation

Explain the effect of changes in temperature on enzyme activity in terms of kinetic energy, shape and fit, frequency of effective collisions and denaturation

Explain the specificity of enzymes in terms of the complementary shape and fit of the active site with the substrate

Explain enzyme action with reference to: active site, enzyme-substrate complex, substrate and product

Investigate and describe the effect of changes in temperature and pH on enzyme activity with reference to optimum temperature and denaturation

Describe enzyme action with reference to the shape of the active site of an enzyme being complementary to its substrate and the formation of products

Describe why enzymes are important in all living organisms in terms of a reaction rate necessary to sustain life

Describe enzymes as proteins that are involved in all metabolic reactions, where they function as biological catalysts
