What is the difference between active and passive transport across the plasma membrane? what is the difference between active an
d passive transport across the plasma membrane? active transport means that the cell is actively going after substances that it wants to bring into the cell, whereas passive transport means that the cell just waits for the substance to cross the membrane. active transport implies that the cell is working with other cells, whereas passive transport implies that the cell does not cooperate with other cells. active transport is atp dependent, whereas passive transport uses only the kinetic energy of the particles for movement across the plasma membrane. active transport is used to move substances down their concentration gradient, whereas passive transport is used to move substances against their concentration gradient?
The correct answer is "active transport is ATP dependent whereas in passive transport molecules use kinetic energy to move across the membrane." in active transport cells use molecules embedded on the cell membrane called carriers in the presence of energy. cells use energy and carriers because molecules must move against concentrated gradient inside the cell. on the hand, passive transport is a process by which molecules move from the region of high concentration to the region of low concentration across plasma membrane until balance is obtained on both sides of the membrane. once equilibrium has been achieved in passive transport the movement of molecules stops.
The osteoblasts, which should have been building the new bone
Explanation:
Bones are the one of the types of connective tissues and have hard extracellular matrix. Osteoblasts are the cells that serve in formation of extracellular matrix of bones as these cells secrete collagen fibers and inorganic salts present in the matrix of bone. Hence, if a bone is not able to heal after fracture, osteoblast cells should be checked for their activity.
