Soccer (assuming field player) is a sport which is 90% aerobic.
True
False
Question 50
Glucose is necessary for fatty acid oxidation because...
its derivative, pyruvate, is condensated with carbonic acid to form oxaloacetate, which in turn is a necessary carbon compound in the citric acid cycle
it is needed to convert fatty acids to fatty acyl-CoA which in turn is oxidized to acetyl CoA
glucose is decarboxylated into cytochrome oxidase which is a necessary intermediate in the citric acid cycle
its derivative, acetyl CoA, is condensated with carbonic acid to form lactase, which in turn is a necessary carbon compound in the citric acid cycle
Question 51
In aerobic ATP production, the role of oxygen is to...
to keep the electron transport chain operational
to accept electrons from the 3rd cytochrome and thereby oxidizing it so it can accept new electrons
act as a oxidizing agent by accepting electrons from the electron transport chain and combining with hydrogen ions (protons)
all of the above
Question 52
The primary purpose of the citric acid cycle is...
aerobic glycolysis
gluconeogenesis using lactate
the decarboxylation of carbon compounds to produce NADH.
the shuttling of hydrogen ions through the inner mitochondrial membrane
Question 55
Which of the following is the best predictor of marathon running performance?
A person exercises in their âfat burning zoneâ for 4 hours at 35% VO2peak. The O2 cost of exercise at that work rate is 0.5L/minute. Following exercise the subject rewards himself with an ice-cream sundae (700kcal). The following statement is true(assume 5kcal/lit of O2):
A.
The subject is in neutral energy balance
B.
The subject consumed fewer calories than they expended during exercise
C.
The subject consumed more calories than they expended during exercise
D.
