Aerobic and Anaerobic respiration Flashcards
(21 cards)
What is aerobic respiration?
Respiration using oxygen to break down food molecules
What is the main respiratory substrate used in aerobic respiration?
Glucose
What is the word equation for aerobic respiration?
glucose + oxygen → carbon dioxide + water + energy released
What are the chemical symbols for the aerobic respiration equation?
C6H12O6 + 6O2 → 6CO2 + 6H2O + energy released
Where do the first stages of aerobic respiration occur?
In the cytoplasm of cells
Where is most of the energy released during aerobic respiration?
In the mitochondria
What is anaerobic respiration?
Respiration that occurs without oxygen
Which type of respiration can human muscle perform for short periods?
Anaerobic respiration
What is the equation for anaerobic respiration in human muscle?
glucose → lactic acid + energy released
What do yeast cells produce during anaerobic respiration?
Ethanol and carbon dioxide
What is the equation for anaerobic respiration in yeast?
glucose → ethanol + carbon dioxide + energy released
Where does anaerobic respiration occur in cells?
Only in the cytoplasm
What is the presence of oxygen in aerobic respiration?
Present
What is the presence of oxygen in anaerobic respiration?
Absent or in short supply
How is glucose oxidized in aerobic respiration?
Completely
How is glucose oxidized in anaerobic respiration?
Incompletely
What are the products of aerobic respiration?
Carbon dioxide and water
What are the products of anaerobic respiration in mammalian muscle?
Lactic acid
What are the products of anaerobic respiration in yeast?
Ethanol and carbon dioxide
How much energy is released in aerobic respiration?
Relatively large amount
How much energy is released in anaerobic respiration?
Small amount, but quickly
