Gaseous exchange Flashcards
What is aerobic respiration
Aerobic respiration is a chemical reaction that transfers energy to cells.
What are the waste product of aerobic respiration?
The waste products of aerobic respiration are carbon dioxide and water.
What is the chemical reaction that happens in aerobic respiration?
C6H12O6 + 6O2 -> 6CO2 + 6H2O
What is anaerobic respiration?
In anaerobic respiration, glucose breaks down without oxygen. The chemical reaction transfers energy from glucose to the cell. Anaerobic respiration produces lactic acid, rather than carbon dioxide and water.
When does anaerobic respiration occur?
Imagine sprinting 100 metres. You need to transfer energy from glucose to your muscles very quickly. However your body cannot get oxygen to its muscles quickly enough for aerobic respiration to occur. This is why anaerobic respiration happens instead.
What is the formula anaerobic respiration?
C6H12O6 -> 2C3H6O3
What is lactic acid?
Lactic acid is the waste product produced during anaerobic respiration.
How is lactic acid produced?
When you run fast there is a chemical reaction called anaerobic respiration. This reaction transfers energy from glucose to your cells without oxygen. The only product of this reaction is lactic acid.
Through what organ does air move into the lungs?
Air moves into the lungs through the windpipe
What is the proper term for breathing?
Venitation
What are the tiny air sacs in the lungs called?
Alveoli
What are the products of aerobic respiration?
Carbon dioxide and water
Where in the cell does respiration happen?
Mitochondria
What reaction occurs in yeast?
Fermentation
Which organ system helps us breathe?
Gas exchange system
