Questions & Step-by-Step Solutions
What is the primary site of glucose reabsorption in the nephron?
Step 1: Understand what the nephron is. The nephron is the basic unit of the kidney that helps filter blood and produce urine.
Step 2: Learn about glucose. Glucose is a type of sugar that our body uses for energy.
Step 3: Know that when blood is filtered in the nephron, some substances, including glucose, need to be reabsorbed back into the body.
Step 4: Identify the parts of the nephron. The nephron has several parts, including the glomerulus, proximal convoluted tubule, loop of Henle, distal convoluted tubule, and collecting duct.
Step 5: Focus on the proximal convoluted tubule (PCT). The PCT is the first part of the nephron after the glomerulus.
Step 6: Understand that the PCT is where most glucose reabsorption happens. This means that glucose is taken back from the filtrate (the fluid that becomes urine) into the blood.
Step 7: Learn that glucose reabsorption in the PCT uses active transport. This means that energy is required to move glucose against its concentration gradient.
