Homeostasis Basics

Question 1

Key points need to include in answers

Answer 1

Body temp to low:
. Link to to little kinetic energy of molecules / molecules move to slowly
. This means fewer collisions / fewer ESC formed

Question 2

Points keep forgetting

Answer 2

. Homeostasis in mammals involves physiological control systems that maintain the internal environment so it within restricted limits

. The possession of separate mechanisms involving negative feedback controls departures in different directions from the original state, giving a greater degree of control

. Blood glucose to low
Cells are unable to carry out normal activities because there’s not enough glucose to carry out respiration to provide energy - insufficient energy available for cell metabolism

. Important point- counteract change

. Multiple feedback systems means activity increase or decrease level so it returns to normal
