Question

How many steps are there in the process of glycolysis, the metabolic pathway that converts glucose into pyruvate?

• A. 6.
• B. 8.
• C. 10.
• D. 12.

Hint:

Glycolysis is a 10-step metabolic pathway that is crucial for energy production and occurs in the absence of oxygen.

Answer 1

The Correct Option is C

Step 1: Glycolysis Overview.
Glycolysis is a ten-step enzymatic pathway that transforms a single glucose molecule (\( C_6H_{12}O_6 \)) into two pyruvate molecules (\( C_3H_4O_3 \)). This process takes place in the cell's cytoplasm and is anaerobic. 

Step 2: Analysis of the Ten Steps. 
The initial five steps represent the energy investment phase, followed by the energy payoff phase in the subsequent five steps. The pathway consumes 2 ATP molecules and produces 4 ATP molecules, yielding a net gain of 2 ATP per glucose molecule. \[ \therefore \text{The process of glycolysis consists of 10 steps.} \]
