TRANSPORT MECHANISMS ACROSS CELL MEMBRANE 2
Storyboard Text
- What's up Grand pa! Mom told me that your good in science when you were young. can i ask you some question about science?
- Yes sure Andrei! What is your question?
- Grand pa, what is "Active Transport?
- Active Transport is the cell need this to store essential chemicals like Glucose, and Amino Acids. Primary Active Transport is define as Active Transport Fueled by Adenasine trihosphate or ATP.
- Grand pa, if there is primary active transport there will be a secondary?
- there is primary active transport uses Chemical energy to transport all species of solutes across a membrane against their concentration gradient.
- OH! Okay I only have one question left .
- yes! there is a secondary. secondary active transport uses the energy store in these gradients to move other substance against their own gradients.
- Grandpa my last question is.. how Active transport works?
- Active transport is the movement of dissolved molecules into or our of a cell through the cell membrane, from a region of lower concentration to a region of higher concentration. the particles move against the concentration gradient, using energy released during respiration
- Oww sheeeeeeeeeeeeeeeeesh GRAND PA! Thanks for the knowledge your really good at science
- Your welcome... don't be shy to ask me if you have question.
