Exam preparation - Producing ATP from metabolic pathways

10 important questions on Exam preparation - Producing ATP from metabolic pathways


The amount of ATP that an individual produces is dependent on their energy requirements. More ATP is required by the individual when their energy expenditure increases. For example, during strenuous exercise, an individual manufactures up to 500 g ATP every minute. However, it is estimated that a 70 kg male that leads a sedentary lifestyle still needs around 210 kg of ATP per day.

i) Which metabolic processes are required to create a lot of ATP during strenuous exercise?
Choose 4 of the following processes: Glycolysis, gluconeogenesis, glycogenesis, glycogenolysis, common metabolic pathway, anaerobic respiration.

G, GY, C and AN R

I) Why is glycolysis required to create a lot of ATP during strenuous exercise?

G itself creates T A and P

P can be converted into A CA

A CA then enters the C to G a lot more A

I) Why is glycogenolysis required to create a lot of ATP during strenuous exercise?

Break down G in the liver into free G

G then taken out of the C into the B

G can then be trafficked to where it is required

Once it reaches these organs, G and the C  are employed to generate a lot of ATP from the G

I) What are examples of glucose from glycogenolysis being used during strenuous exercise?

G can be taken to G dependent organs such as the B and the K or other O's that require G at that time such as the M

I) Why is the common metabolic pathway required to create a lot of ATP during strenuous exercise?

C derived A CA enters the C to generate a lot of A

I) What happens to the electron rich coenzymes NADH and FADH2 after they leave the citric acid cycle?

Taken to the E where the E's from the C E's are passed along the chain of protein C's in the E

I) What does anaerobic respiration do?

A R converts P to L, causing the L A (L) to build up in the M

I) What type of reaction is the conversion of pyruvate to lactate?

A R R that produces N from N

I) What is the NAD+ from the anaerobic respiration used for?

Step 6 of G, which allows G to continue, making T A at a time

Ii) Which hormone assists the individual in obtaining energy from glycogen during strenuous exercise?

G activates the G breakdown process, called G
