Active transport Flashcards
What does active transport need
ATP
How do ions and molecules move
Ions and Molecules are moved across the membranes against a concentration gradient
Intrinsic proteins
Molecules or ion, needs to be transported, combines with a soecific intrinsic protein called a pump
What does ATP transfer
ATP transfers a phosphate group to the pump inside the membrane
What happens to the pump after the phosphate group has been transferred
Causes the pump to change shape and transports the ion or molecules across the membrane, the molecle or ion is relesed into the cell
What does processes involving active transport include
Includes protein synthesis, muscles contraction, nerve impulse, transmisson and absorbtion of minerals such as nitrates by a plant root cell
