Document Summary
Describe how molecular structure of proteins gives them unique function. Define phenotypic plasticity and explain how environment influences photosynthesis via transcription factors. Explain why epigenetic modifications can have long-lasting, or multi-generational effects. Molecular structures: how atoms in mol in your body are arranged. Transforming chem energy from food into low entropy molecular structures (and a little heat) When cells are manufacturing new proteins = biosynthesis. Genome does not contain every single protein produced (selective) Ribosomes can make any type of protein (all depend on the sequence of the. Any function in your body is ultimately proteins changing shape. Every function performed in your body has at least one protein responsible for it. Ex: muscles can transform chem energy into mechanical energy bc of specific proteins that muscles cells make. Diff species make slightly diff hemoglobin structure gives species their own cardiovascular capabilities. Some species have slightly different isoforms of that protein have same protein but their aa sequence differs slightly.
