No need to worry about the for your Test.

The sodium - potassium pump is an example of active transport (needs ATP). Energy required to move ions or molecules across the membrane. In this case three sodium ions are transported across the membrane and two potassium ions are brought into the cell (across the membrane)

The Glucose-to-pyruvate-to-lactate formation should have ATP yield 7ATP (2 ATP, 2 NADH), which is 22% of 32 ATP released during aerobic cycle (OR 18% for 39ATP = 7ATP [anaerobic]+32ATP [aerobic]). How are these values 5% for anaerobic glycolysis and 95% for anaerobic glycolysis estimated?

1 = Anaerobic (rapid) results in pyruvate-to-lactate formation, releases about 5% of energy within original glucose molecule. This is calculated from glucose energy potential being 38 ATP molecules and 5% being approx. 2 ATP molecules. (varying sources will state slightly different numbers.

You will not be required to do this type of calculation.

2 = Aerobic (slow) pryruvate-to-acetyle-CoA-to-citric acid cycle and electron transport of the remaining energy within original glucose molecule about 95%

Can all the irreversible reactions be considered as rate-limiting? If no, what requirements do they need to meet to be rate-limiting?

2. The glucose-to-glucose-6-phosphate formation catalysed by hexokinase is said to be irreversible reaction. However, during glycogenolysis glucose-6-phosphate transforms into glucose in the presence of glucose-6-phosphorylase. Therefore, should the 1st reaction of glycolysis be considered as irreversible?
