When eColi cells are exposed to a hypertonic solution the bacteria produce a transporter protein that can move k plus into the cells Of what value is the active transport of k plus which requires ATP?

The Na+-K+pump. This carrier protein actively pumps Na+ out of and K+ into a cell against their electrochemical gradients. For every molecule of ATP hydrolyzed inside the cell, three Na+ are pumped out and two K+ are pumped in.

What is the type of transport in which a cell goes against the concentration gradient in order to diffuse substances within?
Active transport is used to move molecules and ions across a membrane against their concentration gradient. "Active" means that the transporter requires energy to do its job (eg. glucose).
Which type of transport requires assistance from membrane proteins?
cellular transport nop, is passive transport
What type of transport requires energy to move molecule?
Active transport requires energy to move a molecule.
What type of transport requires energy move a molecule?
Active transport requires energy to move a molecule.
What are the two main kinds of movement that happens into and out of the cell?
Ions and molecules move into and out of the cell by two main methods:Passive transport does not require any energy. Molecules wither diffuse into the cell or enter the cell via transporter proteins located on the cell membrane.Active transport requires the use of ATP molecules to move ions or molecules into and out of the cell.
What has to be present for Pyruvate to enter the mitochondria?
The mitochondrial membrane has special transporter proteins which are needed to transport pyruvate. This transport also requires ATP.
What is the type of transport in which a cell goes against the concentration gradient in order to diffuse substances within?
Active transport is used to move molecules and ions across a membrane against their concentration gradient. "Active" means that the transporter requires energy to do its job (eg. glucose).
What is only used in active transport?
A secondary active transporter. An example is Na+/glucose transporter. It has to move the glucose in but uses the sodium gradient to push it in instead of directly using ATP.Na gradient was made with Na/K ATPase which uses ATP (therefore it is called primary active transporter). In secondary active transport one molecule must have a higher gradient and uses ATP indirectly.
Which type of transport requires assistance from membrane proteins?
cellular transport nop, is passive transport
What types of transport requires no energy?
Passive Transport
What type of transport requires energy to move molecule?
Active transport requires energy to move a molecule.
What type of transport requires energy move a molecule?
Active transport requires energy to move a molecule.
What are all the differences between active and passive transport?
Passive transport occurs when the concentration of something on one side of membrane is different from the concentration on the other side. It occurs when that substance can pass through the membrane, and always in the direction of more -> less. No energy is required to make the substance move; in fact, this movement generates energy. This is like rolling a rock down a hill--it just does it on its own.Active transport occurs in the opposite direction, from less -> more. It requires energy for transport. This is like rolling a rock up a hill--you have to push it the entire way!Both involve the transport of a substance across a membrane, and the change in concentrations on different sides of a membrane. Both are also important to the proper functioning of a cell.Active transport requires energy, but passive transport requires none.Active transport requires a special protein to make the transport occur, but passive transport requires none.
What does not describe passive transport?
Active transport requires energy.
What is differs between active transport and passive transport?
Active transport requires energy; passive transport does not.
The difference between active transport and passive transport is?
Active transport requires energy; passive transport does not.
How does active transport differ from passive transport-?
Active transport requires energy while passive transport does not.
