Which of the following processes takes place in the cytosol of a eukaryotic cell?

• A. Protein synthesis on the rough ER
• B. Glycolysis
• C. DNA replication
• D. Photosynthesis

Answer: (B)

Verified step by step guidance

1. Understand the location of cellular processes: Different processes occur in specific parts of the cell. For example, protein synthesis on the rough ER occurs on the rough endoplasmic reticulum, DNA replication occurs in the nucleus, and photosynthesis occurs in the chloroplasts.
2. Identify the process that occurs in the cytosol: The cytosol is the liquid found inside cells, distinct from the organelles. Glycolysis is a process that takes place in the cytosol.
3. Review the steps of glycolysis: Glycolysis is the metabolic pathway that converts glucose into pyruvate, releasing energy and forming ATP and NADH in the process.
4. Consider the role of glycolysis in cellular metabolism: Glycolysis is the first step in cellular respiration and is crucial for energy production in both aerobic and anaerobic conditions.
5. Conclude that glycolysis is the correct answer: Since glycolysis occurs in the cytosol, it is the process among the options provided that takes place in this part of the cell.
