1 The peak rate that an animal can synthesize ATP could best

1.) The peak rate that an animal can synthesize ATP could best be measured by what means?

a.) Calculating daily metabolic rate

b.) Calculating Aerobic capacity

c.) CO2 production

d.) Taking muscle biopsy and looking for lactic acid levels

2.) Which of the following animals has the most expensive mode of locomotion?

a.) eagle

b.) sloth

c.) gold fish

d.) cheetah

Solution

The peak rate that an animal can synthesize ATP could best be measured by measuring the CO2 production as the ATP is produced by by TCA and electron trasport chain and the reducing equivalents of the electron transport chain are produced by TCA so the whole process of energy production is a reflection of the level of CO2 production. Hence the option: c.) CO2 production is correct  

2.) Which of the following animals has the most expensive mode of locomotion?

Birds like eagle use flight to procure thier prey and since the velocity of the eagle is very high and its body is having high metabolic rate it uses the most energy for locomotion hence it has the most expensive mode of locomotion.
