Cellular Transport
Storyboard Text
- The bigger the difference, the steeper the concentration gradient and the faster the molecules of a substance will diffuse. The direction of me is with the concentration gradient
- It is being transported to deliver protein to the body.
- Water is one of the molecules!
- No. I am a passive process and do not require the cell to give up any of it’s energy
- Hey, I'm diffusion
- I'm Frank! I'm learning about cell transport and I have some questions for you and your buddies. First off for you, do you require energy and if so where do you get it from?
- Very cool! What are your concentration gradients and direction of movement?
- Amazing! Give me a molecule that uses your transport.
- What is the reason why your substance is being transported in or out of the cell in terms of the role it plays in the functioning of the human body
- Without me your cells would not be able to have the proper levels of water to work at their best.
- Small molecules such as water can pass directly through the membrane because they are neutral and so small. I am very similar to simple diffusion.
- Hey I'm osmosis
- Diffusion happens in any type of mixture while osmosis always occurs across a semipermeable membrane
- No, I don't need energy, I am a passive transport process
- My direction of movement is described as movement with the concentration gradient. The particles will move from an area of high concentration to an area of low concentration.
- What's the difference between you two?
- That's amazing! What particles go across the membrane?
- Is there anything else I should know about you?
- Hey osmosis, I'm frank. I was just wondering if you need energy and if so where does it come from
- Cool! What are yourconcentration gradients and direction of movement?
- carbohydrates, amino acids, nucleosides, and ions. These are polar and charged molecules that need to go across the plasma membrane
- I use carrier proteins and channel proteins. The cell membrane separates the extracellular and intracellular spaces.
- I move my materials with and against the concentration gradient.
- No, I do not require energy!
- Hey I'm facilitated transport
- Hey facilitated transport, I'm Frank. Can you tell me whether there is energy required, and where you get this energy from?
- Amazing! What are your chemical / molecular components of the cell membrane, the location of the extracellular and intracellular spaces, and the tonicity of the intracellular and extracellular environments
- What are your concentration gradients and direction of movement?
- Wow! What are some molecules that use your type of transport and why?
- Yes I use energy. The energy is used to move molecules across the membrane against a concentration gradient by breaking down ATP
- Here's one: Transportation of amino acids across the intestinal lining in the human gut
- I require specialized carrier proteins and the expenditure of cellular energy
- How's it going, I'm active transport
- Hey active transport, I'm Frank. I need to ask you some questions. Is energy required for you and if yes, where do you get it from?
- Nice! Do you require a carrier protein?
- Cool! Can you give me an example of a molecule that uses your transport and why?
- Good question! I transport vesicles. Vesicles help transport materials that an organism needs to survive and recycle waste materials. I also will mention it doesn't require a carrier protein!
- Yes I do require energy. I get my energy from ATP
- I am against the concentration gradient and I move ions from areas of low concentration to areas of high concentration
- Hello, I'm endocytosis
- Hey, I'm Frank I talked to some of your friends, and I have some questions for you. First off, Is energy required for you and if yes, where do you get it from?
- What are your concentration gradients and direction of movement?
- I see. Could I get a specific example of a molecule that uses your method of transport and why?
- Hello, I am exocytosis
- Like endocytosis, I transport vesicles. Vesicles help transport materials that an organism needs to survive and recycle waste materials. I also will mention it doesn't require a carrier protein!
- I need energy in the form of adenosine triphosphate or ATP
- I move against the concentration gradient, from a lower to higher concentration.
- I see. What are your concentration gradients and direction of movement?
- Hey exocytosis I'm Frank and I have some questions for you. First off, do you require energy and if yes, where do you get your energy from?
- Cool! Is there any molecules that use your type of transport, and why are they important
