Biological Systems & Process Flashcards
Write the word equation for respiration
glucose + oxygen → carbon dioxide + water
Which process uses carbon dioxide and water?
Photosynthesis
Which process uses glucose and oxygen?
Respiration
Which gas is needed for respiration?
CO2
Name the gas produced in respiration that needs to be removed
O2
What is gas exchange?
Moving oxygen from the air into the blood, and removing waste carbon dioxide from the blood into the air
Describe the features of the alveoli
Increase surface area of lungs
Moist, thin walls (just one cell thick)
A lot of capillaries
How does the oxygen move from the capillaries into the alveoli?
By diffusion
In which direction does oxygen diffuse in capillaries?
From the air into the blood
In which direction does carbon dioxide diffuse in capillaries?
From the blood into the air
Write 3 things energy is needed for
Growth and repair
Movement
Control of body temperature in mammals/birds
Write the word equation for aerobic respiration
glucose + oxygen → carbon dioxide + water
Why is aerobic respiration called aerobic respiration?
Oxygen is used
Where does respiration take place in cells?
In the mitochondria
What are the tiny air sacs in the lungs called?
Alveoli
