Question

The end product of oxidative phosphorylation is?

B VENKAT · Accepted Answer

## CORE INFORMATION
✓ **Answer**: D
## CONCEPT FRAMEWORK
 **Primary Concept**: Oxidative Phosphorylation
 **Related Topics**: Cellular Respiration, Electron Transport Chain, ATP Synthesis
 **Prerequisites**: Basic understanding of cellular respiration and energy production in cells.
## SOLUTION PATHWAY
**Given Information**:
  The question asks for the end product of oxidative phosphorylation.
  Oxidative phosphorylation is the final stage of cellular respiration.
**Method & Steps**:
 1. Understand Oxidative Phosphorylation:
  Reasoning: Oxidative phosphorylation is the process where ATP (adenosine triphosphate) is produced using the energy released during the oxidation of NADH and FADH2.  This occurs in the electron transport chain located in the inner mitochondrial membrane.
  Formula/Rule:  The overall reaction can be simplified as:  $NADH + H^+ + \frac{1}{2}O_2 ightarrow NAD^+ + H_2O$
 2. Identify the End Product:
  Working: The primary purpose of oxidative phosphorylation is to generate ATP, which is the cell's main energy currency. Water ($H_2O$) is also a byproduct of the process.
  Key Point: While NADH is an *input* to oxidative phosphorylation, it is not the *end product*. Oxygen ($O_2$) is also an *input*, acting as the final electron acceptor.
 3. Final Step:
  Result: The end products of oxidative phosphorylation are ATP and water ($H_2O$).
  Verification: The ATP generated is used to power various cellular processes, and water is released as a byproduct of the electron transport chain.
 ## OPTION ANALYSIS
[A] :x: NADH is a reactant (input) in oxidative phosphorylation, not an end product.
[B] :x: $O_2$ is a reactant (input) in oxidative phosphorylation, not an end product. It acts as the final electron acceptor.
[C] :x: ADP is a reactant (input) in oxidative phosphorylation, it is converted to ATP.
[D] ✓: $ATP + H_2O$ are the end products of oxidative phosphorylation. ATP is the primary energy currency of the cell, and water is a byproduct.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing reactants with products:  Remember that reactants are consumed during the reaction, while products are formed.
  2.Focusing only on ATP:  While ATP is the major product, water is also a significant byproduct.
 **Quick Tips**:
  1.Remember the overall goal of oxidative phosphorylation:  ATP production.
  2.Visualize the electron transport chain and its role in generating a proton gradient that drives ATP synthesis.
