Biological molecules
Monomers and polymers
Carbohydrates
Lipids
Proteins
Nucleic acids are important information-carrying molecules
ATP
Water
Inorganic ions
Cells
Cell structure
All cells arise from other cells
Transport across cell membranes
Cell recognition and the immune system
Organisms exchange substances with their environment
Surface area to volume ratio
Gas exchange
Digestion and absorption
Mass transport
Genetic information, variation and relationships between organisms
DNA, genes and chromosomes
DNA and protein synthesis
Genetic diversity can arise as a result of mutation or during meiosis
Genetic diversity and adaptation
Species and taxonomy
Biodiversity within a community
Investigating diversity
Energy transfers in and between organisms
Photosynthesis
Respiration
Energy and ecosystems
Nutrient cycles
Organisms respond to changes in their internal and external environments
Stimuli, both internal and external, are detected and lead to a response (A-level only)
Nervous coordination
Skeletal muscles are stimulated to contract by nerves and act as effectors
Homeostasis is the maintenance of a stable internal environment
Genetics, populations, evolution and ecosystems
Inheritance
Populations
Evolution may lead to speciation
Populations in ecosystems
The control of gene expression
Alteration of the sequence of bases in DNA can alter the structure of proteins
Gene expression is controlled by a number of features
Using genome projects
Gene technologies allow the study and alteration of gene function allowing a better understanding of organism function and the design of new industrial and medical processes
Practical skills
Practical skills and required practical activities
