Question

A researcher observes a eukaryotic cell lacking functional peroxisomes. Which of the following metabolic processes would be MOST directly affected?

D VINOD · Accepted Answer

## CORE INFORMATION
✓ **Answer**: B
## CONCEPT FRAMEWORK
 **Primary Concept**: Peroxisome function in eukaryotic cells
 **Related Topics**: Lipid metabolism, oxidative reactions, beta-oxidation
 **Prerequisites**: Understanding of cellular organelles and their roles.
## SOLUTION PATHWAY
**Given Information**:
A eukaryotic cell lacks functional peroxisomes.
**Method & Steps**:
1. Identify the primary function of peroxisomes.
  Reasoning: Peroxisomes are organelles involved in various metabolic processes, including the breakdown of very long-chain fatty acids (VLCFAs) through beta-oxidation, and the detoxification of reactive oxygen species.
  Formula/Rule: N/A
2. Determine which metabolic process is most directly impacted by peroxisome dysfunction.
  Working:  Glycolysis occurs in the cytoplasm, protein synthesis primarily in ribosomes, and DNA replication in the nucleus.  These processes are not directly dependent on peroxisomes.
  Key Point:  Peroxisomes are crucial for the breakdown of VLCFAs, a process that cannot be efficiently performed by other organelles.
3. Conclude the most affected metabolic process.
  Result: The breakdown of long-chain fatty acids is the metabolic process most directly affected by the lack of functional peroxisomes.
  Verification: The other options are not directly related to peroxisome function.
 ## OPTION ANALYSIS
A :x: Glycolysis occurs in the cytoplasm and is independent of peroxisomes.
B ✓: Peroxisomes are essential for the beta-oxidation of very long-chain fatty acids.  Their malfunction directly impairs this process.
C :x: Protein synthesis is primarily a function of ribosomes and the endoplasmic reticulum.
D :x: DNA replication occurs in the nucleus and is unrelated to peroxisome function.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing peroxisomes with other organelles (e.g., lysosomes, mitochondria): Understanding the unique functions of each organelle is crucial.
  2.Overlooking the role of peroxisomes in fatty acid metabolism: Focusing only on their role in detoxification may lead to incorrect conclusions.
 **Quick Tips**:
  1.Remember the key function of peroxisomes: breakdown of very long-chain fatty acids and detoxification.
  2.Associate peroxisomes with lipid metabolism.
