Question
1. Identify the way that each of the following moves in a cell. (diffusion, facilitated diffusion, active transport, cotransport)Vesicles along microtubules
Microtubules in a cilium as the cilium beats
Movement of proteins in the plane of a plasma membrane
Movement of phospholipids in the plane of a plasma membrane
Movement of water molecules across a membrane (through an aquaporin channel)
Movement of sodium ions out of a cell and potassium ions into a cell
Movement of hydrogen ions into a lysosome
Movement of oxygen molecules into a cell
Movement of carbon dioxide molecules out of a cell
2.Proton pumps are found on the plasma membrane but also are important components of membranes within a cell.
a. What organelle or organelles in the cytoplasm have proton pumps?
b. Why are these pumps important for the functions of these organelles?
Please help!
Explanation / Answer
1.vesicles: active transport microtubules: active transport movement of proteins: facilitated diffusion movement of phospholipids : diffusion movement of water molecules : facilitated diffusion movement of sodium ions: cotransport hydrogen ions : active transport oxygen : diffusion co2 : diffusion 2. a mitochondria and chloroplasts have proton pumps b the proton pumps creates a electrochemical gradient which is used to generate ATP.
