1 B io F actsheet January 1998 Number 12 Respiration Aerobic respiration can be divided into four stages: 1. Glycolysis (G) 2. The Link reaction (LR) 3. Kreb?s cycle (K) 4. The electron transfer chain (ETC) These take place in different parts of the cell (Table 1) and the detailed biochemistry of these reactions is shown overleaf. Respiratory quotients The respiratory quotient (RQ) is defined as the ratio of carbon dioxide produced to oxygen consumed per unit time by an organism: volume of CO2 produced volume of O2 consumed Different substances give different RQ values Cellular respiration is the process by which the energy contained in organic molecules is made available for all of the active

Cellular Respiration Stage 4: Electron Transport Chain Cellular respiration What?s the point? The point is to make ATP! ATP ATP accounting so far? Glycolysis ? 2 ATP Kreb?s cycle ? 2 ATP Life takes a lot of energy to run, need to extract more energy than 4 ATP! A working muscle recycles over 10 million ATPs per second There?s got to be a better way! I need a lot more ATP! There is a better way! Electron Transport Chain series of proteins built into inner mitochondrial membrane along cristae transport proteins & enzymes transport of electrons down ETC linked to pumping of H+ to create H+ gradient yields ~36 ATP from 1 glucose! only in presence of O2 (aerobic respiration) O2 That sounds more like it!

mitochondrion

Mitochondria are bounded by a double membrane. Each of these membranes is a?phospholipidbilayer with embedded proteins. The outermost membrane is smooth while the inner membrane has many folds. These folds are called cristae. The folds enhance the "productivity" of cellular respiration by increasing the available surface area. The double membranes divide the mitochondrion into two distinct parts: the intermembrane space and the mitochondrial matrix. The intermembrane space is the narrow part between the two membranes while the mitochondrial matrix is the part enclosed by the innermost membrane. Several of the steps in cellular respiration occur in the matrix due to its high concentration of enzymes.
