What is required for the phosphagen system to function?

ADP, PCr

Which enzyme catalyzes the breakdown (and resynthesis) of PCr?

creatine kinase

T or F? Pcr is stored in the liver?

F

T or F? It is possible to increase the amount of stored PCr by supplementing with creatine monohydrate.

T

T or F? More stored PCr should increase the power of the phosphagen system.

T

T or F? More stored PCr should increase the capacity of the phosphagen system.

T

What speeds up glycolysis?

increased PFK activity, more PFK

What slows down glycolysis?

H+, glycogen depletion

T or F? Glycolysis cannot happen without a steady supply of NADH.

F

Place the stages of aerobic metabolism in the order in which they occur.

glycolysis, citric acid cycle, electron transport chain

Put the following molecules in the order in which they appear/get involved in the process of aerobic metabolism.

glucose, pyruvate, acetyl CoA, ATP synthase

In aerobic metabolism, what does the O2 we breathe in turn into?

water

What is the space inside the inner mitochondrial membrane called?

matrix

In what stage in aerobic metabolism is CO2 produced?

citric acid cycle

In which stages of aerobic metabolism are electrons from the fuel substrate passed to electron carriers?

citric acid cycle, glycolysis

What is produced during the electron transport chain?

H2O, ATP, NAD+

T or F? In the ETC, complex IV has a higher affinity for electrons than complex I.

T

What enzyme is responsible for the most ATP resynthesis in AEROBIC metabolism?

ATP synthase
