Transport across the membrane is often accomplished by transmembrane protein channels, and in some cases, the transport requires the input of ATP.Answer and Explanation: Simple diffusion is when molecules can pass through the cell's membrane unaided. This is possible for molecules such as water, ...
The cell can use diffusion to bring in water and small ions. The way that diffusion occurs depends on the molecule that is being brought in or expelled out of the cell. Diffusion is a type of passive transport, meaning it does not require energy from the cell to take place....
it requires no input of additional energy; the concentration gradient alone is enough to drive the process. Types of Diffusion Diffusion across the cell membrane is either simple or facilitated. Simple diffusion Facilitated diffusion Mechanism Molecules move directly across the membrane without the aid ...
Step-by-Step Text Solution:1. Understanding Passive Transport: Both simple diffusion and facilitated diffusion are types of passive transport. This means that they do not require energy (ATP) to occur.2.

Single-Cell Analysis is a growing field that endeavors to obtain genetic profiles of individual cells. Disruption of cell–cell junctions and digestion of extracellular matrix in tissues requires tissue-specific mechanical and chemical dissociation proto
[8] macrocycles, shows that, a large amount of precipitate generate immediately after simply mixing UO2(NO3)2·6H2O and [HMPyVB]I in the aqueous solution, which remains unchanged after hydrothermal treatment. Similar phenomenon is observed even if an interface diffusion method is used to reduce...
Writing in Nature in 1939, Chaik and Duthie suggested, "… it seemed to us likely that it was an enzyme acting on some substrate in the skin, causing the removal of a barrier to the rapid diffusion of intradermally injected fluids."14 The enzyme activity was subsequently defined as a ...

Both of these processes are examples of passive transport. The difference is that facilitated diffusion requires a protein channel for the molecule,... Learn more about this topic: Diffusion | Overview & Definition from Chapter 4/ Lesson 15 ...
