There are 2 types of respiration...what are they?
|
Aerobic and anaerobic respiration.
|
|
|
What is aerobic respiration?
|
this is the breaking down of organic material in the presence of oxygen & produces large amount of energy.
|
|
|
In the cells of plants and animals, a series of what takes place?
|
a series of chamical reactions take place under the control of enzymes, in very small structures called mitochondria
|
|
|
When oxygen combines with respiratory substrate such as glucose releases what?
|
a large amount of energy and produces carbon dioxide and water
|
|
|
What is anaerobic respiration?
|
this is the break down of organic material in the absence of oxygen
|
|
|
It also consists of a series of what?
|
chemical reactions under the control of enzymes, but glucose is only a small amount of energy is released
|
|
|
What is the respiratory surface?
|
the surface through which oxygen leaves the living organism
|
|
|
The respiratory system enables what?
|
the rapid and efficient exchange of gases between the organism and its environment
|
|
|
What is external respiration?
|
the exchange of gases at the respiratory surface
|
|
|
Why is the respiratory surface large and thin?
|
so that there is a large surface area through which gases exchange can occur.they are alo very thin so that the gases only have a short distance to diffuse
|
|
|
Why is the respiratory surface moist?
|
becuse the gases have to dissolve in the moisture in order to diffuse across the durface
|
|
|
Why is the respiratory surface supplied with gases?
|
gases are usually brought to and from the respiratory surface by some kind of breathing movement
|
|
|
Why is the respiratory surface supplied with blood?
|
most respiratory surfaces in animals are supplied with blood vessels which bring some gases and take away others
