Energetics

Question 1

What is the 2nd law of Thermodynamics?

Answer 1

The entropy of an isolated system will always increase over time

Question 2

What are the 2 definitions of energy?

Answer 2

1. The capacity to do work

2. The capacity to increase order

Question 3

What is bioenergetics?

Answer 3

Energy flow and transformation in an animal

Question 4

How do we measure metabolic rate?

Answer 4

Substances used or produced

Question 5

What are the 5 factors influencing metabolic rate?

Answer 5

1. Temperature
2. Body Mass
3. Physiology
4. Activity
5. Digestive state

Question 6

What is the difference between basal and standard metabolic rate?

Answer 6

Basal is for an endothermic animal and is within their thermoneutral zone
Standard is for ectothermic animals and is at a specific temperature

Question 7

Do smaller or larger animals have a higher metabolic rate?

Answer 7

Larger

Question 8

What is the maximum metabolic rate (MMR)?

Answer 8

When MR increases with an increasing activity until the highest point

Question 9

Does MR increase or decrease during the digestive process?

Answer 9

Increase

Question 10

What is the specific dynamic action?

Answer 10

The amount of energy expenditure above the RMR for digestion
