The limit of fast transport implies that molecules move into and out of the the cell much more frequently than they are involved in reactions. The molecules are uniformly distributed in VT under these conditions, so that the probability that a randomly chosen molecule is in VC is simply \(\...

Answer to: Fill in the blank. The molecules which use energy from ATP to move organelles along certain components of the cytoskeleton are called...
How do water molecules move through the cell membrane during osmosis? What two conditions must be present for osmosis to occur? How is osmosis across the cellular membrane controlled? PLASMOLYSIS INTRODUCTION If a plant cell is immersed in a solution that has a higher solute concentration than tha...
What they didn’t know was how tubulin and another cell organelle known as flagella fit into the process. Now, a new study from University of Georgia shows the mechanism behind tubulin transport and its assembly into cilia, including the first video imagery of the process. The study was ...
HRG1's function has been demonstrated to be closely coupled with V-type ATPases and the lumenal pH of the organelle, as acidic conditions increase free heme solubility and a decrease in pH also raises HRG1's affinity for heme by transport from endosomes in cell lines [44,112]. Early ...
3A). This is a typical case that the vacuole is the site for biosynthesis and intermediates move out from this organelle. Another alkaloid, nicotine, might also be produced in the lumen of the vacuole or vesicles, which later fuse with the vacuole. An enzyme essential for a late step of ...
The chloroplast is an organelle specific for eukaryotic oxygenic photosynthetic organisms, namely algae and land plants. It is mostly known for being the host of a fundamental process called photosynthesis, which generates molecular oxygen and organic molecules in the Earth’s biosphere since billion ye...
What is an example of diffusion and osmosis and use the plant cells as an example in a demonstration of these processes? Why are dead cells not able to carry out osmosis? What is the role of each organelle in a bacteria cell? What do osmosis and active transport differ? What is the di...
