Document Summary
An animal"s work: use chemical energy to decrease entropy (create molecular order) Describe how the molecular structure of proteins gives them unique functions. Define phenotypic plasticity and explain how the environment influences protein synthesis via transcription factors. Explain why epigenetic modifications can have long-lasting, or even, multi-generational effects. Molecular structures how atoms in molecules in your body are arranged. Determined by both covalent and non-covalent bonds. *biosynthesis transforming chemical energy from food into low entropy molecular structures (and of course a bit of heat) proteins proteins. Composed of sequences of amino acids determined by genetic code. Proteins are large molecules, composed of amino acid sequences (common amino acids) Proteins are the workhorses of the body they determine the work animals can do. Proteins changing shape movements, thoughts and memories, etc. E. g. muscles can transform chemical energy into mechanical energy because of the specific proteins that muscles cells manufacture.
