Cell Respiration 1. Respiration: o Organism scale: gas exchange o Cell respiration: the process by which cells take food molecules and use them to make ATP o Anaerobic respiration Glycolysis Fermentation (special case of glycolysis) 1 glucose 4 ATPs o Aerobic respiration Requires oxygen Includes glycolysis in the process; first step 1 glucose 36-38 ATPs 2. Lewis Acids and Bases o Lewis acid: releases an electron (may be energetic) o Lewis base: absorbs an electron o Lewis “buffers” o H+, e- o NAD+  NAHD o H+, e- o FADH  FADH 2 + 3. Glycolysis o The splitting of a single glucose to release energy (does NOT require oxygen; it is anaerobic) o Overview o Glucose (6 C’s) 2 pyruvates (3 C’s each) + 4 ATP 2 pyruvates 2 lactates

Unformatted text preview: 4. Krebs Cycle o Occurs in or adjacent to mitochondria o Basic goal: produce NADH & FADH 2 o (uses electrons from the pyruvates) o Overview o 2 pyruvates (from Glycolysis) 6 CO2 + NADH + FADH 2+ 5. Electron Chain Transport & Chemiosmosis o ECT o Occurs only in mitochondria o Utilize special enzyme complex called cytochromes o Requires oxygen (see notebook for overview) 2 O-2 + 4H+ H2O (2) o Chemiosmosis o Primary process for making ATP in aerobic metabolism o Requires a membrane surface (internal mitochondrial membrane complex) o Pumps are powered by electrons- in the ECT o Adding a proton gate (permanently open) to IMMC Moved protons go through the gate.
