What is Animal physiology the study of?
|
The study of animal function
(i.e. how an animal works). |
|
|
What is Animal ecophysiology the study of?
|
The study of how the environment affects animal physiology.
|
|
|
The questions that ecophysiology addresses are
|
How do.....
How are... Where does... |
|
|
The study of animal physiology is important for humans as it is fundamental
in understanding |
the biology of all animals
human health and disease the heath and disease of pets, farm animals and harvested animals biotechnology |
|
|
6 levels of Biological ogrganisation
|
1/ Chemical
2/ Cellular 3/ Tissue 4/Organ 5/ Organ system 6/ Multicelluar organism |
|
|
What is ECOLOGY the study of?
|
how organisms interact with each other and their nonliving
(physical) environment |
|
|
Ecophysiology focuses on answering what two central questions?
|
1. How do animals carry out their functions?
2. Why do animals carry out these functions? |
|
|
What is the compound in light cells that reacts with ATP?
|
luciferin
|
|
|
What is product of light production?
|
luciferyl-AMP (adenosine monophosphate).
|
|
|
What happens when luciferyl-AMP reacts with oxygen?
|
creates an Electron-excited state
|
|
|
What is the catalyst that catalysis light production?
|
Luciferase
|
|
|
What happens when the excited electrons return to their ground state?
|
they emit photons of
light. |
|
|
What happens to the oxygen when light is not being produced?
|
intercepted by mitochondria
|
|
|
Light cells produce light only if there is...?
|
stimulation from the nervous
system |
|
|
Stimulation by the nervous system causes the mitochondria to be...?
|
bathed in nitric oxide (NO)
|
|
|
nitric oxide (NO) does what in light cells?
|
blocks mitochondrial use of oxygen so oxygen is allowed through to
react with luciferyl-AMP |
|
|
Adaptive significance of light productions
|
Light is produced by male fireflies to attract mates
respond to the flashes which are specific to their species |
|
|
Mechanistic physiology
- Emphasises...? |
how things happen
|
|
|
Evolutionary physiology
- Emphasises...? |
evolutionary origins.
|
|
|
Comparative physiology:
- Systematically compares..? |
the ways that various animals carry out
similar functions. |
|
|
Environmental physiology
- Investigates how a |
nimals respond physiologically to environmental conditions and challenges.
|
|
|
Integrative physiology
- Emphasises the |
study of how things happen across all levels of biological organisation.
