Factors affecting Metabolic rate

Question 1

What is Metabolic Rate indirectly determined by?

Answer 1

Energy value of food (minus waste)

amount of heat produced

amount of metabolic water produced

amount of oxygen used up

Question 2

Standard Metabolic Rate (SMR)

Answer 2

Level required for resting lifestyle (but animals often fail to co-operate

Question 3

Routine/Resting Metabolic Rate (RMR)

Answer 3

Level required for minimal activity (acknowledgement difficulties in measuring)

Question 4

Maximum Metabolic Rate (MMR)

Answer 4

Maximum level possible during excising activity

Question 5

Aerobic scope meaning

Answer 5

Maximum amount of oxygen available for aerobic activity and therefore physiological performance

Question 6

How to calculate Absolute Aerobic Scope (AS)?

Answer 6

Absolute AS = MMR -RMR

Absolute AS = Maximum Metabolic rate - Resting Metabolic Rate

Question 7

What does Metabolic Rate vary with?

Answer 7

Mass (Complex, positive relationship)

Temperature

Environmental Oxygen

Genetic Differences

Food

Question 8

Mass-Specific metabolic rate

Answer 8

The metabolic tart of a gram of tissue depends on the size of the animal

Small animals have more metabolically active tissues
