BIOL 141 Lecture Notes - Lecture 6: Organism, Phototropism, Mitochondrial Matrix
Document Summary
Vesicular transport: proteins - secreted, sugar/peptide breakdown, dna-mrna. Dna goes through ribosome, trna creates own chain, rna. Nucleus: transcription, new mrna- rough er (free/bound) --> free in cytoplasm, bound -> intermembrane space. Protein translated by ribosomes move from rough er to other places. Membrane bound organelles: from membrane transport to other places. Golgi body: another membranous organelle, cytoskeleton (train tracks) Fusion: stick 2 together, morph and fall into golgi. Cis-golgi: proteins, modified, packaged again, gets secreted (lipid-bound vesicle), moves towards plasma membrane, gets fused w/ membrane, dumps stuff out. Lysosomes: cellular uptake, cellular transport (glucose) -> transporter in plasma membrane (channel), animal cell only, cell makes lytic enzymes --> packaged into active/passive transport, lysosome. Plastid --> chromoplast: what gives the jade flower its color, store pigments. Yes: through photosynthesis (chloroplast, thylakoid- where light reactions take place) Input/output: photosynthesis, light energy, co2, produces energy and glucose. Plants: use inorganic molecules to manufacture sugars ***
