Review Questions:
1. Under what conditions does 02 consumption provide a good estimate of the metabolic rate? Under Aerobic conditions.
2. What factors should be considered when the metabolic rate measured is to be a reliable measure of the basal metabolic rate? The animal must be resting. The animal must be in its thermoneutral zone. The animal must be fasting in order to avoid the calorigenic effect of food.
3. What is allometry and what type of information does it provide? Allometry is the scaling coefficient of processes within the body.
4. How does the metabolic rate vary with body mass? The larger the animal, the higher the metabolic rate. Since larger animals have more cells, larger animals require more oxygen, leading to higher metabolic rate.
5. How does the mass specific metabolic rate vary with body mass? It decreases as mass of animal increases.
6. What are some commonly observed values of the allometry coefficient? Multiples of 0.25, such as 0.75 for metabolic rate, 0.25 for lifespan, and 1.25 for cerebral gray matter.
7. What is the respiratory quotient and what is the range of values observed? The ratio of CO2 expired to 02. Range of values is 0-250 ml 02/hr.
8. Now that non linear curve fitting methods can be easily accomplished by using standard personal computers, is there any compelling reason to transform equations so as to linearize the trends above? It helps because it smooths out the data instead of being all squished together.
9. When examining the slopes for the plots of log(MR) versus log(M) (Slide#22) and log (MR/M) versus log(M) (Slide#23), it is seen that Y-intercept values are identical for both plots, but the slope values are
