Question

1. why do some molecules require atp in order to be moved in and out of a cell membrane?
2. which cell process do you think white blood cells use to digest pathogens and dying cells?
3. why is it important to have a proper amount of electrolytes in the body?

Explanation:

• Question 8: Some molecules move against the concentration gradient. Active transport needs energy. ATP powers transport proteins for this movement.
• Question 9: White blood cells use phagocytosis. It is a process where cells engulf and digest pathogens and dying cells.
• Question 10: Electrolytes are important for nerve and muscle function, fluid balance, and maintaining proper cell function.

Answer:

1. Some molecules move against the concentration gradient. Active transport needs energy. ATP powers transport proteins for this movement.
2. Phagocytosis.
3. Electrolytes are important for nerve and muscle function, fluid balance, and maintaining proper cell function.
