Principles of secondary active transport across the plasma membrane.

Active transport through a plasma membrane. Active transport allows a molecule to cross the membrane from lower concentration to higher concentration.1 Molecule enters carrier. 2 Breakdown of ATP induces a change in shape that 3 drives the molecule across the membrane

Principles of secondary active transport across the plasma membrane.

Facilitated diffusion of glucose by the glucose uniporter.  The transport of glucose across the plasma membrane can be in either direction, but is mostly into the cell. The glucose uniporter has two states: open to the exterior of the cell (A) and open to the interior of the cell (B). In either state, the glucose uniporter will bind glucose and undergo a conformational change, delivering glucose to the opposite side. The direction of glucose transport is driven by the concentration gradient.

It’s a fact: Nobody lives forever. Aging is unavoidable. But what actually happens when you age? Why does your hair go grey? Why does your skin

The Science of Getting Old Infographic. In the cell-division process, telomeres keep DNA and RNA from becoming damaged. If you’re in your chances are you’re getting grey hair. This is due to the (Grey Hair Tips)

This is a Cell Transport Flow Chart. Materials that move through the cell can use active or passive transport. Passive Transport doesn't use energy such as in osmosis and simple diffusion. Materials go from areas of high concentration to areas of low concentration. Active transport uses energy and goes from low concentrations to high against the gradient. -Enjoy! Science from Murf LLC
