What is the primary difference between anaerobic and aerobic respiration?
A
Anaerobic respiration occurs in the mitochondria, while aerobic respiration occurs in the cytoplasm.
B
Anaerobic respiration uses glucose, while aerobic respiration uses fatty acids.
C
Anaerobic respiration occurs without oxygen, while aerobic respiration requires oxygen.
D
Anaerobic respiration produces more ATP than aerobic respiration.
Verified step by step guidance1
Understand the basic definitions: Aerobic respiration is a process that requires oxygen to produce energy, while anaerobic respiration does not require oxygen.
Identify the location of each process: Aerobic respiration primarily occurs in the mitochondria, whereas anaerobic respiration occurs in the cytoplasm.
Consider the substrates used: Both processes can use glucose, but aerobic respiration can also utilize fatty acids and other substrates.
Compare the energy yield: Aerobic respiration produces significantly more ATP compared to anaerobic respiration due to the complete oxidation of glucose.
Recognize the role of oxygen: The key difference is that aerobic respiration requires oxygen to proceed, while anaerobic respiration occurs in the absence of oxygen.
