Respiration Flashcards
(15 cards)
What type of reaction is respiration
Chemical reaction
What does respiration do
Releases energy in the form of ATP
What are the two types of respiration
Aerobic and anaerobic
How are the two types of respiration different
Aerobic involves oxygen and anaerobic doesn’t
What is the main site of aerobic respiration in animals
Mitocondria
Word equation for aerobic respiration
Glucose + oxygen -> carbon dioxide + water + ATP
Chemical equation for aerobic respiration
C6H12O6 + 6O2 -> 6H20 + 6CO2 + ATP
What does respiration release energy from
Glucose
Where does anaerobic respiration take place
Cytoplasm
When does the body carry out anaerobic respiration?
Vigorous exercise - sprinting etc
Oxygen needed elsewhere
Anaerobic respiration in humans word equation
Glucose -> lactic acid + a little ATP
Why does aerobic respiration release more energy than anaerobic respiration?
Energy stored in bonds in glucose
Oxygen breaks all bonds to release most energy
Less bonds broken = less energy
What does lactic acid build up lead to
Muscle fatigue and pain
Anaerobic respiration in plants and yeast word equation
Glucose -> ethanol and carbon dioxide
What factors impact the rate of respiration
Oxygen levels
Heat
Ph
Glucose concentration
