2.2.6 Anaerobic Respiration Flashcards
What is anaerobic respiration?
When energy is released from glucose without oxygen
When does anaerobic respiration often happen in humans?
During intense exercise when we cannot take in enough oxygen
What is the word equation for anaerobic respiration in humans?
Glucose –> Lactic Acid + Energy
What are the products of anaerobic respiration in humans?
Lactic Acid + Energy
What is the reactant of anaerobic respiration in humans?
Glucose
Why do you continue breathing after intense exercise?
The extra oxygen is needed to break down lactic acid
What do we call the extra oxygen needed to break down lactic acid after intense exercise?
The oxygen debt
Why does the body normally respire aerobically?
It releases more energy from glucose
It does not produce lactic acid which causes cramps
What does lactic acid do to the muscles?
Causes cramps
When might a plant respire anaerobically?
If its roots are waterlogged so cannot get oxygen.
The special type of anaerobic respiration carried out by yeast is called…
fermentation
What is yeast?
A microorganism (fungi)
What is fermentation?
A type of anaerobic respiration done by yeast
What is the equation for fermentation?
Glucose –> Ethanol + Carbon Dioxide + Energy
What are the products of fermentation?
Ethanol + Carbon Dioxide + Energy
