What is the scope of biochemistry? BB450 Biochemistry: The molecules of life Life is literally everywhere Extremophiles are found in extreme conditions They are Archaea Methanogens: strict anaerobes – produce methane from carbon dioxide and hydrogen Halophiles: require very high salt for growth Thermoacidophiles: require high temperature and acid for growth Categorizing the Systems of Life Prokaryotic and eukaryotic cells Differences between prokaryotes and eukaryotes Organelle Prokaryotes Eukaryotes Nucleus No – DNA present but not separate from rest of cell Present Plasma membrane Present Present Mitochondria No – Enzymes for oxidation reactions located on Present plasma membrane Endoplasmic reticulum No Present Ribosomes Present Present Chloroplasts No – photosynthesis (if present) is localized in Present in green plants chromatophores The key biological macromolecules Building block nucleotides amino acids sugars Another macromolecule Anabolic vs catabolic processes
