Biology: The Cell: 06: Cell Transport - Active Transport - Medical Animation
MEDICAL ANIMATION TRANSCRIPT: In this video, we'll discuss active transport. Active transport is when particles move from an area of low concentration to high concentration. This is also known as moving against the concentration gradient. The key thing to remember is that active transport requires energy. If passive transport is like a ball naturally rolling down a hill, active transport is the opposite. You can get the ball back up the hill, but you're going to have to expend some energy to do it. Cells require this type of substance movement in order to function properly. For example, heart muscle cells responsible for making your heart beat, move molecules or ions against their concentration gradient. So, what are some of the main types of active transport? We have endocytosis, exocytosis, and protein pumps. Sometimes a cell uses active transport to pull in large particles using its cell membrane. This is called endocytosis. One type of endocytosis is called phagocytosis. This often happens when the cell takes in some type of nutrient. In another type of endocytosis called pinocytosis, the cell takes in fluids by creating pockets in the cell membrane. The cell can ingest a large amount of fluid this way by pinching off these cell membrane pockets into the cytoplasm. The opposite of endocytosis is exocytosis. Exocytosis is when something needs to exit the cell. The cell can remove large molecules or wastes this way by fusing the membrane bound vesicles containing them with the cell membrane, forcing them out of the cell. A good way to remember that exocytosis is a way for things to leave the cell is that it shares the first two letters with exit. You can also remember that endocytosis is a way for things to move into the cell because each shares the first two letters with enter. Sometimes the cell uses special protein pumps to move small molecules or ions against the concentration gradient into or out of the cell. An example of this is the sodium potassium pump. In this process, the pump uses energy in the form of ATP molecules to move sodium ions out of the cell and then move potassium ions into the cell. Protein pumps used an active transport require energy because the molecules or ions are moving from an area of low concentration to high concentration. In summary, active transport is when the cell uses energy to move substances in or out of the cell against the concentration gradient via endocytosis, exocytosis, or protein pumps. [music]

What attorneys say about MLA and The Doe Report:
"This past year, your company prepared three medical illustrations for our cases; two in which we received six figure awards; one in which we received a substantial seven figure award. I believe in large part, the amounts obtained were due to the vivid illustrations of my clients' injuries and the impact on the finder of fact."

"There is nothing like a great graphic depicting the real nature and extent of a victim's injuries to get full value for your client. I use Medical Legal Art for mediations as well as trial."

"Your firm is great to work with and, most importantly for me, you get the job done on time and with the utmost professionalism. You should be proud of all those you employ, from KJ to Ben B. I've been especially pleased over the years with the work of Brian and Alice, both of whom seem to tolerate my idiosycratic compulsion to edit, but I've not found a bad apple in the bunch (and, as you know, I've used your firm a bunch!). I look forward to our continued professional relationship."

"Medical Legal Art wins our firm's highest accolades for professionalism and exhibit quality. In fact, many of the doctors I work with request color copies of your outstanding artwork to show to patients during the informed consent process."
