What else can I help you with?
What is it called when transport protein binds with the needed molecule?
passive transport
Is transport protein binds with the needed molecule active transport?
B passive transport i think This is cassidy evans from ramah high school
What type of transport does a small molecule enter a cell with help from a membrane protein additional energy is needed to complete this process?
Facilitated
What type of organic molecule is needed for active transport?
ATP (adenosine triphosphate) is the organic molecule needed for active transport. It provides the energy required to pump molecules against their concentration gradient across a cell membrane.
How much energy is needed for passive transport?
None
A small polar molecule enters a cell with help from a membrane protein. No additional energy was needed to complete this process. What type of transport is this?
Facilitated
Do facilitated diffusion require energy?
No energy is needed because it's a part of passive transport, not active transport.
Is it active or passive transport or osmosis when particles move through protein doorways?
Since you are talking about the movement of particles, it would not be osmosis, because osmosis is the movement of water. Technically speaking, you could consider water a particle, but it is assumed that this question refers to movement of soluteparticles, and not solvent particles. Then, to determine if the movement is active or passive, one needs to know if energy is required and if the movement is up or down the concentration gradient. No energy requirement, it is passive. If a source of energy is needed, then it is active transport. Not sure what a protein doorway is. If you mean a pore, then the movement may be passive, or even facilitated diffusion.
How is passive transport different then active transport?
Passive transport does not require energy input and relies on the concentration gradient to move molecules across the cell membrane. Active transport requires energy (usually in the form of ATP) to move molecules against the concentration gradient.
What function does ATP serve in mitosis?
Sorry my answer is not too accurate... don't have my bio textbook on me. From memory, ATP phosphorylates the protein that causes active transport. It would give the energy needed for a protein to actively transport the molecule or atom of choice through the pore. Now active transport mitosis? I've never heard of that before. Are you saying that ATP activates a protein (which transfers thing) during mitosis?
Compare active transport to passive transport?
Active transport requires energy, whereas passive transport does not. Passive transport is normally something moving from an area of high concentration to low concentration (with the grain). Active transport is something moving from an area of low concentration to an area of high concentration(against the grain).
What is the active transport and passive transport?
The requirements of passive transport through the cell membrane (phospholipid bilayer) of an animal cell are that the molecule is non-polar or small enough to pass by the non-polar phospholipid tails. This is because, for there to be passive transport, no energy must be used to transport the molecule from outside of the cell to inside.
