Students should be able to describe photosynthesis as an endothermic reaction in which energy is transferred from the environment to the chloroplasts by light. 4.4.1.2 Rate of photosynthesis Students should be able to explain the effects of temperature, light intensity, carbon dioxide concentration, and the amount of chlorophyll on the rate of photosynthesis. Students should be able to: measure and calculate rates of photosynthesis extract and interpret graphs of photosynthesis rate involving one limiting factor plot and draw appropriate graphs selecting appropriate scale for axes translate information between graphical and numeric form. (HT only) These factors interact and any one of them may be the factor that limits photosynthesis. (HT only) Students should be able to explain graphs of photosynthesis rate involving two or three factors and decide which is the limiting factor. (HT only) Students should understand and use inverse proportion – the inverse square law and light intensity in the context of photosynthesis. (HT only) Limiting factors are important in the economics of enhancing the conditions in greenhouses to gain the maximum rate of photosynthesis while still maintaining profit. **Required practical activity 6: investigate the effect of light intensity on the rate of photosynthesis using an aquatic organism such as pondweed. ** 4.4.1.3 Uses of glucose from photosynthesis The glucose produced in photosynthesis may be: used for respiration converted into insoluble starch for storage used to produce fat or oil for storage used to produce cellulose, which strengthens the cell wall used to produce amino acids for protein synthesis. To produce proteins, plants also use nitrate ions that are absorbed from the

By the end of the powerpoint students would have covered: 4.4.2.3 Metabolism Students should be able to explain the importance of sugars, amino acids, fatty acids and glycerol in the synthesis and breakdown of carbohydrates, proteins and lipids. Metabolism is the sum of all the reactions in a cell or the body. The energy transferred by respiration in cells is used by the organism for the continual enzyme controlled processes of metabolism that synthesise new molecules. Metabolism includes: conversion of glucose to starch, glycogen and cellulose the formation of lipid molecules from a molecule of glycerol and three molecules of fatty acids the use of glucose and nitrate ions to form amino acids which in turn are used to synthesise proteins respiration breakdown of excess proteins to form urea for excretion.

The nervous system enables humans to react to their surroundings and to coordinate their behaviour. Information from receptors passes along cells (neurones) as electrical impulses to the central nervous system (CNS). The CNS is the brain and spinal cord. The CNS coordinates the response of effectors which may be muscles contracting or glands secreting hormones. stimulus --> receptor --> coordinator -->effector -->response Students should be able to explain how the various structures in a reflex arc – including the sensory neurone, synapse, relay neurone and motor neurone – relate to their function. Students should understand why reflex actions are important. Reflex actions are automatic and rapid; they do not involve the conscious part of the brain. Required practical activity 7: plan and carry out an investigation into the effect of a factor on human reaction time.
