Verified step by step guidance

Step 1: Begin by understanding the concept of tubular secretion. Tubular secretion is a process in the nephron of the kidney where substances are actively transported from the blood into the tubular fluid to be excreted in urine.

Step 2: Review the functions of tubular secretion. It plays a role in removing waste products (e.g., drugs and toxins), regulating blood pH by secreting hydrogen ions or bicarbonate, and eliminating excess ions like potassium.

Step 3: Analyze the options provided in the question. Identify which processes are directly related to tubular secretion (e.g., removal of drugs, regulation of blood pH, elimination of excess potassium ions).

Step 4: Consider the process of glucose reabsorption. Glucose is typically reabsorbed in the proximal tubule of the nephron through active transport mechanisms, not secreted into the tubular fluid. This process is distinct from tubular secretion.

Step 5: Conclude that the correct answer is the process that does not involve tubular secretion, which is 'Reabsorption of glucose.'
