BIOL240 Lecture 1: BIOL240 Midterm Test Notes chapter 4 eukaryotes
Document Summary
Larger than bacterial or archaeal cells: (well duh, they consist of more components, and they"re more vast, (nucleus, chloroplast, mitochondrion this should all be drilled in your. Possess a cell wall and complex internal cytoskeleton. Plays a role in the storage and expression of information. Non-membrane bound nucleolus exists within the nucleus (ribosome synthesis) Spatial separation: transcription occurs in nucleus, translation occurs in cytoplasm. Uses er/golgi apparatus: proteins are often extensively modified in these structures prior to reaching their destinations. Uses the electron transport chains (etc) to produce atp: via the process of chemiosmosis. Also participates in later stages of cellular respiration. Use electron transport chains to produce atp (chemiosmosis) Use the atp they produce to fixate carbon into organic compounds: these organic compounds are usually some sort of glucose. Each has their own dna, ribosomes, and transcription machinery. Can replicate independently of the rest of the cell.
