A: B: Unique to A Common to both Unique to B

A: facultative anaerobes B: obligate anaerobes Unique to A Common to both Unique to B Can also respire with O2 Survive in an O2 environment Can switch from anaerobic to aerobic Can respire without O2 Breakdown molecules Glycolysis Fermentation Cannot respire in presence of O2 Cannot survive in O2 environment Must be anaerobic

A: aerobic B: anaerobic Unique to A Common to both Unique to B Citric acid cycle (krebs) Oxidative phophorylation With O2 1 glucose ~ 38 ATP Glycolysis first step Electron acceptors or redox reactions Produce ATP Fermentation Without O2 1 glucose ~ 2 ATP

A: glycolysis B: citric acid cycle Unique to A Common to both Unique to B Starts with glucose (glucose>>pyruvate) Happens in both aerobic and anaerobic respiration outside mitochondria 2 ATP formed Each step catalyzed by enzymes CO2 formed as waste Pyruvate >> acetyl coA>> cycle of hydrocarbons Only in aerobic respiration Inside mitochondria

A:oxidized B: reduced Loses e- or charge Losing potential E Unique to A Common to both Unique to B Loses e- or charge Losing potential E Reducing agent Glucose, NAD+, C in CO2, lower electronegative one, ADP Transfer e- Redox reactions Energy transfer C, carbon chain molecules, S,N,P Gains e- Gaining potential E Oxidizing agent NADH, O2, F, higher electronegative one, ATP
