Question

Which of these is NOT a metabolic process?

D VINOD · Accepted Answer

## CORE INFORMATION
✓ **Answer**: 4
## CONCEPT FRAMEWORK
 **Primary Concept**: Metabolism
 **Related Topics**: Cellular processes, bioenergetics, transport mechanisms
 **Prerequisites**: Understanding of metabolic pathways (anabolism and catabolism), cell biology, and transport processes.
## SOLUTION PATHWAY
**Given Information**:
  Photosynthesis, Respiration, Digestion, Diffusion of oxygen across a cell membrane are given as options.
  We need to identify which is NOT a metabolic process.
**Method & Steps**:
 1. Define Metabolism:
  Reasoning: Metabolism encompasses all the chemical reactions within a living organism that are necessary to maintain life.  This includes both anabolism (building up complex molecules) and catabolism (breaking down complex molecules).
 2. Analyze each option:
  Working:
  * Photosynthesis:  The process by which plants convert light energy into chemical energy (glucose). This is a metabolic pathway.
  * Respiration: The process of breaking down glucose to release energy (ATP). This is a central metabolic pathway.
  * Digestion: The breakdown of food into smaller molecules that can be absorbed by the body. This is a metabolic process, involving enzymatic reactions.
  * Diffusion of oxygen across a cell membrane: This is a passive transport process driven by a concentration gradient. It doesn't involve chemical reactions or energy transformations in the same way that metabolic processes do.  It's a physical process, not a chemical one, supporting metabolism but not being metabolism itself.
 3. Identify the non-metabolic process:
  Result: Diffusion of oxygen across a cell membrane is the only option that is not a metabolic process.
  Verification: All other options involve energy transformations and/or enzyme-catalyzed reactions, which are hallmarks of metabolic processes.
 ## OPTION ANALYSIS
A :x: Photosynthesis is a major metabolic pathway.
B :x: Respiration is a crucial metabolic pathway for energy production.
C :x: Digestion involves numerous enzyme-catalyzed reactions, making it a metabolic process.
D ✓: Diffusion is a passive transport process; it doesn't involve the chemical transformations characteristic of metabolic processes.  While it supports metabolism (by delivering oxygen), it isn't a metabolic process itself.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing transport processes with metabolic processes:  Transport processes like diffusion facilitate metabolism but aren't metabolic themselves.
  How to avoid: Focus on whether the process involves chemical reactions and energy transformations.
  2.Overlooking the broader definition of metabolism: Metabolism includes both anabolic and catabolic pathways.
  How to avoid: Remember that metabolism encompasses all chemical reactions within an organism.
 **Quick Tips**:
  1.If a process involves enzymes, it's likely a metabolic process.
  2.Metabolic processes always involve energy transformations (either requiring energy or releasing it).
