Membrane Transport

Membrane Transport

Membrane Transport. Passive Transport Moves from high to low concentration Does not require energy. 3) Diffusion Movement of small & polar/nonpolar particles across bilayer. Bilayer is permeable to the particle. O 2 CO 2 Glycerol. No transport proteins are required.

Water regulation in the kidney

Water regulation in the kidney

Water regulation in the kidney. The loop of Henle. The descending limb of the loop of Henle is permeable to water The ascending limb is impermeable. Na + and Cl - ions are actively transported out of the ascending limb and passively move into the descending limb.

Contaminant Transport

Contaminant Transport

Contaminant Transport. CIVE 7332 Lecture 3. Transport Processes. Advection The process by which solutes are transported by the bulk of motion of the flowing ground water. Nonreactive solutes are carried at an average rate equal to the average linear velocity of the water.

In active transport, energy is used to move a solute against its concentration gradient.

In active transport, energy is used to move a solute against its concentration gradient.

Figure 5.13 Primary Active Transport: The Sodium–Potassium Pump. In active transport, energy is used to move a solute against its concentration gradient. For each molecule of ATP used, 2 K + are pumped into the cell and 3 Na + are pumped out of the cell. K +. Outside of cell. Sodium–

5.14 Passive transport is diffusion across a membrane

5.14 Passive transport is diffusion across a membrane

Diffusion is the tendency for particles to move from an area of high concentration to an area of low concentration. Concentration gradient is the difference in concentration on two sides of a membrane Passive transport – no energy required by the cell for this to happen O 2 , CO 2.
