BIOL 1013 Lecture Notes - Lecture 4: Cellular Respiration, Endoplasmic Reticulum, Golgi Apparatus
Document Summary
Cellular respiration c6h1206 (glucose) + 602 = 6co2 + 6h20 + 26 atp (energy) Endomembrane system= nuclear envelope, endoplasmic reticulum, golgi apparatus, lysosomes, mitochondrial membranes, cell membrane, cytoplasm. Outer membrane, inter-membrane space*(critical for maintenance of chemical gradient as form of potential energy), outer membrane. *understand factors that determine permeability of solutes: affect permeability: polarity, charge, size simple diffusion. Molecules diffuse from high to low concentrations (concentration gradient high to low) until equilibrium is reached (equal distribution = no concentration gradient; move randomly throughout, so to remain equal) Cg are a form of potential energy high concentration has high pe, low concentration has low pe. Pe can be harnessed to do work, molecules moving through membranes will create atp. Powered by high concentration gradients, naturally moving down gradients; water follows solutes . Active transport: uses energy, not necessarily in form of atp. Net movement against concentration gradient, requires transport protein and energy input often from.
