Questions about Metabolism, Energetics, and Energy Acquisition

What are the methods of feeding?

What are the different sections of the alimentary system and how do they function?

What are the three types of exocrine secretions and what are their functions?

How does absorption occur while maintaining electrolyte balance?

Describe what metabolism is and explain the difference between anabolism and catabolism?

What is metabolic rate, why is it useful to measure the metabolic rate of an organism, and what is the difference among basal, standard, and field metabolic rate?

How is metabolic rate measured, is it measured directly, and what are some of the techniques that are used to determine metabolic rate?

Since animals cannot be hunting all the time, how do they obtain energy to sustain their basic biological functions while they are not feeding, and how do their metabolic rates change in the process of feeding?

How does body size affect metabolic rate?

What is the surface hypothesis and what is the relationship between metabolic rate and an animals surface area?

How does an animals body regulate and influence temperature change?

How do temperature changes affect individual molecules and enzyme function?

What are ectotherms and how do they regulate temperature?

How do ectotherms cope with extreme cold?

What are heterotherms and how do they regulate temperature?

What are endotherms and how do they regulate temperature?

How does the body detect temperature changes?

What are the costs and benefits of ectothermy?

What are the costs and benefits of endothermy?

Why do animals hibernate?

What are some of the physiological control mechanisms that operate in the regulation of biological rhythms?

What defines a circadian rhythm and distinguishes it from other physiological variables that just happen to coincide with daily cycles?

Besides circadian rhythms, what other biological rhythms exist?

Hibernation involves very specific reductions in metabolism (body heat specifically). To what extent are body heat and other metabolic processes affected during normal daily cycles?

What is extraocular photoreception and why is it an important aspect to understanding biological rhythms?

What is the correlation between photobehavioral response and light patterns?

What is an endogenous clock? How are circadian rhythms distinguished from photoperiodic behavior?
