Which of the following correctly describes some aspect of exocytosis or endocytosis?
1. endocytosis and exocytosis involve active transport.
these two processes require the participation of mitochondria.
2. both processes provide a mechanism for exchanging membrane-impermeable molecules between the organelles and the cytosol.
3. exocytosis and endocytosis change the surface area of the plasma membrane.
4. the inner surface of a transport vesicle that fuses with or buds from the plasma membrane is most closely related to the inner surface of the plasma membrane.

The graph below compares the rates of reaction of a burning candle and an exploding firework. comparing chemical reactions what can you conclude from the graph? the reaction that causes a firework to explode requires less energy to start, and occurs more rapidly than the reaction that causes a candle to burn. the reaction that causes a firework to explode requires less energy to start, and occurs less rapidly than the reaction that causes a candle to burn. the reaction that causes a firework to explode requires more energy to start, and occurs less rapidly than the reaction that causes a candle to burn. the reaction that causes a firework to explode requires more energy to start, and occurs more rapidly than the reaction that causes a candle to burn. mark this and return
