2.4 Metabolism in Conformers And Regulators Flashcards
What are the abiotic factors that affect metabolic rate?
Temperature, salinity and pH
What is a conformers internal environment dependent on?
It’s external environment
How do conformers maintain their metabolic rate?
Using behavioural responses
What type of species has a wider range of ecological special?
Regulator
What is the hypothalamus?
Temperature monitoring centre
What is sweating?
Body heat used to evaporate water in the sweat, cooling the skin
What is vasodilation?
Increased blood flow to the skin increases heat loss
What is the purpose is a decreased metabolic rate?
Less heat produced
What is shivering?
Muscle contraction generating heat
What is vasoconstriction?
Decreased blood flow to sin. Decreases heat loss
Why do hair erector muscles contract?
To trap a layer of insulating air
What is the purpose in an increased metabolic rate?
More heat produced
Why is regulating temperature important?
Optimum enzyme activity and high diffusion rates to maintain metabolism
