Drag each scenario to the appropriate category as it pertains to aerobic or anaerobic breakdown of glucose. Labels Drop Zones Reset All Supplies more ATP than other types of glucose metabolism Provides about 95% of the ATP made from complete glucose metabolism Occurs when oxygen supply in the muscle is limited Provides most the energy needed for events that require a quick burst of energy, ranging from about 30 seconds to 2 minutes Aerobic glucose breakdown (1/2) Occurs when plenty of oxygen is available in the muscle Breakdown products are carbon dioxide and water Supplies more ATP than other types of glucose metabolism Anaerobic glucose breakdown (2/2) Breakdown products include pyruvic acid and lactic acid

The rate of glucose breakdown slows when cells are provided an oxygen-rich environment, which suggests a level of metabolic control. Select all answers which correctly describe how oxygen could (and does) contribute to the activity rate of glycolysis. Increased oxygen raises the speed at which the citric acid cycle runs by acting as a substrate for pyruvate dehydrogenase in the pyruvate bridge reaction, increasing acetyl-CoA levels. An increase in oxygen will raise the rate of electron transport by providing additional electron acceptors, which will increase ATP production. Increased ATP levels feedback to allosterically inhibit the activity of the enzyme regulating glycolysis called phosphofructokinase. Increased oxygen levels slow down breathing rate, decreasing the amount of glucose delivered to each cell.
Complete each sentence outlining the events that occur in aerobic respiration. The catabolism of glucose begins with one or more pathways that yield ______. Next the partially oxidized carbon is fed into the TCA cycle and oxidized completely to ______ with the production of some GTP or ATP, NADH, and FADH2. These pathways also produce ______, FADH2, or both. The NADH and FADH2 formed by glycolysis and the TCA cycle are oxidized by a(n) ______, using oxygen as the terminal electron acceptor. It is the activity of the electron transport chain that conserves most of the energy used to make ______ during aerobic respiration. electron transport chain Krebs cycle ADP pyruvate carbon dioxide NAD carbon monoxide ATP NADH lactose
