Question

Which of the following statements regarding mitochondria is incorrect?

Mr. NARESH KUMAR K · Accepted Answer

## CORE INFORMATION
✓ **Answer**: B
## CONCEPT FRAMEWORK
	**Primary Concept**: Mitochondrial Structure and Function
	**Related Topics**: Cellular Respiration, Membrane Biology, DNA Structure, Protein Synthesis
	**Prerequisites**: Basic understanding of cell organelles and their functions.
## SOLUTION PATHWAY
**Given Information**:
	*  Multiple choice question about mitochondrial structure and function.
	*  Need to identify the incorrect statement.
**Method & Steps**:
	1. Analyze each statement in the context of known mitochondrial structure and function.
		Reasoning: Understanding the structure and function of the mitochondria is key to identifying the incorrect statement. 
	2. Evaluate statement A: Outer membrane is permeable to monomers of carbohydrates, fats, and proteins.
		Working: This is generally true due to the presence of porins in the outer membrane.
		Key Point: The outer membrane is relatively permeable.
	3. Evaluate statement B: Enzymes of electron transport are embedded in outer membrane.
		Working: This is incorrect. The enzymes of the electron transport chain are embedded in the inner membrane.
		Key Point: The inner membrane is the site of the electron transport chain.
	4. Evaluate statement C: Inner membrane is convoluted with infoldings.
		Working: This is true. These infoldings are called cristae and increase the surface area for ATP production.
		Key Point: Cristae are a key feature of the inner membrane.
	5. Evaluate statement D: Mitochondrial matrix contains single circular DNA molecule and ribosomes.
		Working: This is also true. Mitochondria have their own DNA and ribosomes.
		Key Point: Mitochondria have their own genetic material.
	6. Identify the incorrect statement: Statement B is the only false statement.
		Result: Statement B is incorrect.
		Verification: All other statements are factual about mitochondrial structure and function.
 ## OPTION ANALYSIS
[A] :x: This statement is correct; the outer membrane is permeable to small molecules.
[B] ✓: This statement is incorrect. Enzymes of the electron transport chain are in the *inner* membrane.
[C] :x: This statement is correct; the inner membrane has infoldings called cristae.
[D] :x: This statement is correct; the matrix contains mitochondrial DNA and ribosomes.
 ## LEARNING AIDS
	**Common Mistakes**:
		1.[Error 1]: Confusing the location of the electron transport chain. It's in the inner membrane, not the outer.
			[How to avoid]: Remember the inner membrane's role in ATP production via the electron transport chain.
		2.[Error 2]: Thinking the outer membrane is completely impermeable. It is permeable to small molecules, unlike the inner membrane.
			[How to avoid]: Recall that the outer membrane has porins that facilitate passage of small molecules.
	**Quick Tips**:
		1.[Helpful shortcut]: Focus on the location of key functions. The inner membrane is the key site for oxidative phosphorylation.
		2.[Memory aid]: Remember the acronym 'ICE' for Inner membrane, Cristae, Electron transport chain.
