Question

Which is a way in which exocytosis differs from the pumping of calcium ions against a concentration gradient?

A. Exocytosis is a form of passive transport.
B. Exocytosis does not involve a carrier protein.
C. Exocytosis occurs with the concentration gradient.
D. Exocytosis requires an expenditure of energy by the cell

​

Answer 1

Exocytosis is ana ctive transport method and does not include any transport protein. whereas calcium ions pass through the membrane with the help of trans- membrane protein. These proteins make pores inside hydrophobic membrane and allow the ions to pass though it.
