Answer:
Anaerobic
Step-by-step explanation:
- Cellular respiration involves the breakdown of glucose to produce energy in the form of ATP and other by-products such as water and carbon dioxide.
- Cellular respiration can be classified as anaerobic or aerobic respiration.
- Aerobic respiration is a type of respiration that occurs in the presence of oxygen gas and produces energy in the form of ATP, carbon dioxide and water.
- Anaerobic respiration, on the other hand, occurs in the absence of oxygen to produce a minimal amount of energy and also form alcohol or lactic acid as byproducts.
- Fermentation is said to anaerobic since it occurs in the absence of oxygen.
