Question

For each of the following statements indicate whether they are true or false.  If false, explain why, using formulae and equations to support your answer.

a) The regulation of the glycolytic pathway involves allosteric inhibition by AMP.

b)In a eukaryotic cell, the enzymes of glycolysis and the TCA cycle are located in the cytosol and mitochondrial matrix respectively.

c) Mixing pure O2into a yeast culture growing on grape juice will cause the yeast to multiply faster and to metabolize the sugars much more rapidly. The effect on the desired final product (wine) would be a reduced alcohol content.

d) The energetic efficiency of a family-size car (petrol ?motion) is ~25%. By contrast, the energetic efficiency of aerobic carbohydrate metabolism (glucose ? ATP) is less than 10%.

e) Barbiturates disrupt energy metabolism by inhibiting the exit of electrons from complex I of the electron transport chain. This, in turn, blocks the conversion of NADH to NAD+

f) Adrenaline has the ability to upregulate carbohydrate metabolism via stimulation of a signal transduction cascade involving cAMP and multiple protein phosphorylation reactions.
