Question

Which of the following process takes place in anaerobic bacteria ?

B VENKAT · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
	**Primary Concept**: Anaerobic Respiration
	**Related Topics**: Cellular Respiration, Metabolic Pathways, Glycolysis, Krebs Cycle, Electron Transport System (ETS), Link Reaction
	**Prerequisites**: Basic knowledge of cellular respiration processes and differences between aerobic and anaerobic respiration.
## SOLUTION PATHWAY
**Given Information**:
	* Question asks about processes in anaerobic bacteria.
	* Options are different stages of cellular respiration.
**Method & Steps**:
	1. **Recall**: Identify which metabolic pathways occur in anaerobic conditions.
		Reasoning: Anaerobic bacteria perform respiration without oxygen.
		Formula/Rule: N/A
	2. **Evaluate**: Determine which of the given options is the initial pathway in both aerobic and anaerobic respiration.
		Working: Glycolysis is the first step in both aerobic and anaerobic respiration. ETS, Krebs cycle and Link reaction are part of aerobic respiration
		Key Point: Glycolysis does not require oxygen.
	3. **Final step**: Select the correct option.
		Result: Glycolysis is the correct answer.
		Verification: Glycolysis is the only process from the options that occurs in anaerobic conditions.
 ## OPTION ANALYSIS
[A] :x: ETS requires oxygen and occurs in aerobic respiration.
[B] :x: Krebs cycle requires oxygen and occurs in aerobic respiration.
[C] ✓: Glycolysis is the initial pathway in both aerobic and anaerobic respiration and does not require oxygen.
[D] :x: Link reaction is part of aerobic respiration and requires oxygen.
 ## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing aerobic and anaerobic respiration:  Remember that anaerobic respiration doesn't use oxygen.
		2. Assuming all stages of cellular respiration occur in anaerobic bacteria: Only glycolysis happens in anaerobic environments.
	**Quick Tips**:
		1. Glycolysis is the pathway that is common to both aerobic and anaerobic respiration. 
		2.  Remember that ETS, Krebs Cycle and Link reaction are part of aerobic respiration and require oxygen.
