Active and Passive transport
Active and passive transport are biological processes that move oxygen, water and nutrients into the cell, and waste products out of the cell. Active transport requires chemical energy, however passive transport doesn't require any energy.
The difference between active and passive transport is that active transport is when biochemicals are moved from an area of low concentration, to an area of high concentration Passive transport is when biochemicals are moved from an area of high concentration to an area of low concentration.

Passive transport
One process that is related to active and passive transport is osmosis, which is a passive transport because it doesn't require any energy to happen. An example of this is the interstitial fluid (liquid found between the cells), because the interstitial fluid found outside of the kidney is more concentrated than the inside of the nephron tubules. So the water moves out of the kidney and into the blood by osmosis, a passive transport.
Active transport
Active transport occurs in the kidney with glucose molecules, because there is a higher concentration of glucose in the blood than in the nephrons so tho get the glucose to go into the blood active transport is required. This all takes place i the proximal tubule.
