Synthesis of ATP in mitochondria takes place in/on _____

Options

A. matrix
B. cristae
C. outer membrane
D. between membrane

Answer

To answer the question "Synthesis of ATP in mitochondria takes place in/on _____", we will follow these steps:

### Step 1: Understand the Role of Mitochondria
Mitochondria are known as the "powerhouse of the cell" because they are responsible for producing energy in the form of ATP (adenosine triphosphate).

**Hint:** Remember that mitochondria are essential for energy production in cells.

### Step 2: Identify the Structure of Mitochondria
Mitochondria have a unique structure consisting of two membranes:
- An outer mitochondrial membrane
- An inner mitochondrial membrane

**Hint:** Think about the two membranes and their functions in energy production.

### Step 3: Focus on the Inner Membrane
The inner membrane has infoldings known as "cristae." These cristae increase the surface area for biochemical reactions that produce ATP.

**Hint:** Cristae are crucial for the ATP synthesis process.

### Step 4: Locate the ATP Synthesis Process
The synthesis of ATP occurs in the cristae due to the presence of the electron transport chain (ETC) and ATP synthase enzymes (also referred to as Oxyzomes). These structures facilitate the conversion of ADP to ATP.

**Hint:** ATP synthesis is closely linked to the structures found in the cristae.

### Step 5: Choose the Correct Answer
Based on the information gathered, the synthesis of ATP in mitochondria takes place in/on the cristae.

**Final Answer:** Synthesis of ATP in mitochondria takes place in/on **cristae**.
