Active Transport Flashcards
What does ATP stand for ?
Adenosine trisophate.
What does ADP stand for ?
Adenosine diphosphate.
What is atp and adp ?
ATP is a nucleotide. When atp is converted to adp it releases energy and an in organic phosphate molecule. This energy is available for cell processes such as muscle contraction.
Why is endocytosis important ? (Into the cell)
It is important because most molecules needed for the cell to survive cannot normally pass through the plasma membrane. Phagocytosis and pinocytosis are types of endocytosis.
What is the difference between pinocytosis and phagocytosis ?
They are the same except the cells plasma membrane surrounds droplets of fluid containing dissolved solutes.
What is exocytosis ? (Out of the cell)
Material is exported out of the cell via secretory vehicles. This is important removing waste materials from the cell and secreting cellular product eg enzymes or hormones.
What is phagocytosis ?
In this the cells plasma membrane surrounds a molecule such as a food particle. In the extra cellular environment and buds off to form a vacuole that contains a molecule which is then digested by enzymes.
Name the molecule that supplies energy in active transport ?
ATP.
