Homostasis

Question 1

Enzymes denaturing

Answer 1

If conditions are not optimal, then our enzymes can denature
This reduces their ability to catalyse metabolic reactions (chemical reactions)

Question 2

Body conditions homeostasis regulate

Answer 2

Blood sugar
Temperature
Urea
Water
Carbon dioxide

Question 3

Control system components

Answer 3

Receptors
Effectors
Co ordination centres

Question 4

Receptors function

Answer 4

Detect change in environments

Question 5

Effectors

Answer 5

Effectors carry out responses to stimuli that help to restore optimum levels

Question 6

Coordination centres

Answer 6

Coordination centres receive and process information arriving from receptor cells

Question 7

Negative feedback loop (too much water)

Answer 7

Receptors in the brain detect an increase in water level
Pituitary gland receives the information and Co ordinates a response
Pituitary gland releases more ADH
Kidneys reabsorb less water
