What is the site of glycolysis pathway in all living organisms?
(a) Cytoplasm in anaerobes whereas mitochondria in aerobes
(b) Mitochondria in anaerobes whereas cytoplasm in aerobes
(c) Cytoplasm in both anaerobes and aerobes
(d) Mitochondria in both anaerobes and aerobes

Options

A. Cytoplasm in anaerobes whereas mitochondria in aerobes
B. Mitochondria in anaerobes whereas cytoplasm in aerobes
C. Cytoplasm in both anaerobes and aerobes
D. Mitochondria in both anaerobes and aerobes

Answer

To solve the question regarding the site of the glycolysis pathway in all living organisms, we can follow these steps:

### Step 1: Understand Glycolysis
Glycolysis is a metabolic pathway that involves the breakdown of glucose to produce energy. It converts glucose (a six-carbon sugar) into two molecules of pyruvate (a three-carbon compound) while generating a small amount of ATP (energy currency of the cell).

### Step 2: Identify the Location of Glycolysis
Glycolysis occurs in the cytoplasm of the cell. This is true for all living organisms, regardless of whether they are aerobic (requiring oxygen) or anaerobic (not requiring oxygen).

### Step 3: Analyze the Options
Now, let's analyze the given options:
- **(a)** Cytoplasm in anaerobes whereas mitochondria in aerobes: This is incorrect because glycolysis occurs in the cytoplasm for both types of organisms.
- **(b)** Mitochondria in anaerobes whereas cytoplasm in aerobes: This is also incorrect as anaerobes do not have mitochondria.
- **(c)** Cytoplasm in both anaerobes and aerobes: This is correct as glycolysis occurs in the cytoplasm for all organisms.
- **(d)** Mitochondria in both anaerobes and aerobes: This is incorrect since glycolysis does not take place in the mitochondria.

### Step 4: Conclusion
The correct answer is **(c) Cytoplasm in both anaerobes and aerobes**.

### Final Answer
(c) Cytoplasm in both anaerobes and aerobes
