Respiration Flashcards
What is respiration?
An enzyme controlled process (it occurs all the time)
Exothermic reaction (releasing energy)
Glucose + Oxygen ➡️ Carbon Dioxide + Water (+ Energy)
C6H12O6 + 6O2 ➡️ 6CO2 + 6H2O
Where does respiration take place?
Most of these reactions take place in the mitochondria
Mitochondria are tiny rod-shaped parts (organelles); (large surface area) that are found in almost all plant and animal cells as well as in fungal and algal cells (eukaryotes)
Why is respiration important?
Build up/break down molecules
Muscle contraction
Plant minerals
What is aerobic respiration?
An enzyme controlled process (it occurs all the time)
Exothermic reaction (releasing energy)
Glucose + Oxygen ➡️ Carbon Dioxide + Water (+ Energy)
C6H12O6 + 6O2 ➡️ 6CO2 + 6H2O

Why is aerobic respiration important?

What is anaerobic respiration?
Anaerobic respiration is a chemical reaction that releases energy from glucose without using oxygen.
Glucose ➡️ lactic acid
When does anaerobic respiration happen?
It happens when oxygen cannot be delivered to the muscles fast enough (e.g. hard exercise).
What is the equation for anaerobic respiration?
?
How is anaerobic respiration in yeast different to animals?
Anaerobic respiration is different in yeast by them forming ethanol and carbon dioxide. It is known as fermentation. (Both yeast and animals use glucose).
