Where in the human body does simple diffusion occur?
Simple diffusion occurs in various parts of the human body, including the lungs (for gas exchange), the intestines (for nutrient absorption), and the kidneys (for waste filtration). It is a passive process where molecules move across cell membranes down their concentration gradient without the need for a specific protein transporter.
Why aren't osmosis and simple diffusion sufficient for the transport of all substances?
Osmosis and simple diffusion are not sufficient for the transport of all substances due to their nature. They only have the ability to transport substances which can pass through the cell membrane.
In facilitated diffusion which process does not require energy?
Simple and facilitated diffusion are a part of passive transport. This refers to the movement of molecules, atoms and ions across the cell membrane. In both of these processes, molecules move from areas of high concentration to areas of lower concentration because equilibrium is trying to be maintained in living organisms. Simple diffusion just happens randomly and without any aides. Facilitated diffusion uses proteins in the cell membrane to guide polar molecules and ions in and out of the membrane (always to areas of lower concentration) and DOES NOT require ENERGY.Only active diffusion requires energy.
What are some examples of shelter?
A shelter can be anything from an overhang roof to an actual simple building.
What is the respiration of a nematoda?
Nematodes have a simple respiratory system that involves gas exchange occurring through their body surface by diffusion. They lack specialized respiratory organs like lungs or gills, relying instead on passive diffusion of oxygen and carbon dioxide through their thin, permeable cuticle. This allows nematodes to exchange gases with their environment effectively despite their small size and simple body structure.
Are osmotically active substances simple diffusion or active transport?
simple diffusion.
Is simple diffusion the net diffusion of a solvent?
no
What are the 3 types of diffusion?
simple diffusion, osmosis and facilitated diffusion.
Osmosis and diffusion are examples of passive transport?
Yes, osmosis and diffusion are both examples of passive transport.
How does gases enter and leave capillaries?
Simple diffusion.
What happens in simple diffusion?
In simple diffusion, a substance passes through a membrane without any outside intermediary. The rate of diffusion is based on the force exerted..
What are some examples of passive transport?
diffusion facilitated diffusion osmosis
How does facilitated diffusion from simple diffusion?
It doesn't. (answer by RRU member Cyrem)
What are two examples of passive transport?
Two examples of passive transport are simple diffusion, where molecules move across a membrane from an area of high concentration to low concentration, and facilitated diffusion, where molecules move across a membrane with the help of specific transport proteins.
What is passive transport cite examples?
Passive transport is the movement of molecules across a cell membrane without the use of energy. Examples include simple diffusion, where molecules move from an area of high concentration to low concentration, and facilitated diffusion, where molecules pass through a membrane with the help of transport proteins.
The process where a nonpolar molecule can just passively get across a membrane is called?
facilitated diffusion
What is the Epithelium type with the shortest diffusion distance?
Simple squamous epithelium has the shortest diffusion distance due to its thin structure, allowing for rapid diffusion of substances across the epithelium.
