The course is divided into 8 Units (4 covered at AS: Biological molecules, Cells, exchange surfaces & variation (paper1) and 4 covered at A2: Energy, coordination and control, genetics and evolution & control of gene expression (paper2) Understanding the human body, its biochemistry, and physiology are key components along with evolution, ecology, and genetics. Key topics studied are; the structure of biological molecules (amino acids, DNA), transport across membranes (diffusion, osmosis), immunology, gas exchange, the heart, and blood. Genes and the control of proteins, the control of gene expression, and gene technologies. The nervous and hormonal control of the body.
