Question
1. )The catabolic process directly responsible for generation of the most ATP equivalents?
a.) glycolysis
b.) Pyruvate dehydrogenase reaction
c.) oxidative phosphorylation
d.) Kreb’s tri-carboxylic acid cycle
e.) pentose phosphate shunt
2.) The measurement of metabolic rate by indirect calorimetry (Oxygen consumption or CO2 production) has become the most common type of measurement because of what?
a.) It is more accurate than direct calorimetry
b.) It is cheaper, more convenient and can be used on aquatic animals
c.) The animals don’t need to be post-absorptive or kept calm during measurement
d.) It measures both aerobic and anaerobic metabolism, direct calorimetry only measures aerobic
e.) Oxygen uptake is a better gauge of overall ATP cycling in an animal than heat production
3.) Membrane short circuits like those found in brown adipose tissue of mammals and futile cycles generate heat because:
a.) They produce ATP which can be used for heat production
b.) They produce uncoupling protein which is oxidized in Krebs cycle to make heat
c.) they bypass or negate ATP generating reactions causing all potential energy to appear as heat
d.) All Animals need to keep a stable body temperature
e.) none of these are the reason
Explanation / Answer
1.(d) Kreb’s tri-carboxylic acid cycle
2. (a) It is more accurate than direct calorimetry
