In which one of the following processes CO2 is not released?
1. Aerobic respiration in plants
2. Aerobic respiration in animals
3. Alcoholic fermentation
4. Lactate fermentation
Which of the metabolites is common to respiration mediated breakdown of fats, carbohydrates and proteins?
1. Frutose1, 6 - bisphosphate

The three boxes in this diagram represent the three major biosynthetic pathways in aerobic respiration. Arrows represent net reactants or products.
Arrows numbered 4, 8, and 12 can all be:
|3.||FAD+ or FADH2||4.||NADH|
In mitochondria, protons accumulate in the:
2. Outer membrane
3. Inner membrane
4. Intermembrane space
The energy-releasing metabolic process in which substrate is oxidized without an external electron acceptor is called:
3. aerobic respiration
Aerobic respiratory pathway is appropriately termed:
All enzymes of the TCA cycle are located in the mitochondrial matrix except one which is located in inner mitochondrial membranes in eukaryotes and in the cytosol in prokaryotes. This enzyme is:
|1.||lactate dehydrogenase||2.||isocitrate dehydrogenase|
|3.||malate dehydrogenase||4.||succinate dehydrogenase|
The overall goal of glycolysis, the Krebs cycle, and the electron transport system is the formation of:
1. ATP in small stepwise units.
2. ATP in one large oxidation reaction
4. Nucleic acids
How many ATP molecules could maximally be generated from one molecule of glucose if the complete oxidation of one mole of glucose to CO2 and H2O yields 686 kcal and the useful chemical energy available in the high energy phosphate bond of one mole of ATP is 12 kcal?
