What else can I help you with?
Diffusion of glucose and starch?
Glucose and starch diffuse differently due to their molecular sizes. Glucose is a small, soluble molecule that can diffuse easily through cell membranes via facilitated diffusion. In contrast, starch is a large, complex molecule that cannot diffuse through cell membranes and requires enzymatic breakdown before it can be transported into cells.
Why urea can't cross membranes?
Passive diffusion - Urea has its own concentration gradient so it will go from an area of high concentration through the cell membrane into an area of lower concentration.
What is sugar broken down by fructose?
Sugar is broken down into glucose and fructose during digestion. Fructose is a simple sugar that is absorbed into the bloodstream and used for energy by our bodies. It is commonly found in fruits and honey.

What types of molecules diffuse through the cell membranes by facilitated diffusion?
Molecules that are charged or polar, such as ions, glucose, and amino acids, diffuse through cell membranes by facilitated diffusion. This process relies on carrier proteins or channel proteins to help facilitate the movement of these molecules across the membrane.
Is fructose absorbed by active transport?
Because the absorption is from a high concentration to low concentration

What type of substances pass through the membrane by facilitated diffusion?
soluble materials which can diffuse passively .
What are examples of facilitated diffuse?
Entry of CO2 in the leaves during photosynthesis and its exit during night. Absorption of water by root hairs is another example of facilitated diffusion.
What characteristic is shared by simple diffusion and facilitated diffusion?
They both diffuse the particles in order to reduce the boner.
What is diffusion assisted by special protein molecules which bind to substances that diffuse across membranes?
facilitated diffusion
How do water soluble molecules diffuse through biological membranes?
Water soluble molecules diffuse through biological membranes via facilitated diffusion, which involves the use of specific transport proteins embedded in the membrane. These proteins create channels or carriers that allow the molecules to pass through the hydrophobic interior of the membrane. This process is passive and does not require energy input from the cell.
Why urea can't cross membranes?
Passive diffusion - Urea has its own concentration gradient so it will go from an area of high concentration through the cell membrane into an area of lower concentration.
Why the osmosis involves the movement of molecules via special transport protein?
facilitated diffusion
State how facilitated diffusion is achieved?
Facilitated diffusion occurs when a substance is aided across a membrane by a special molecule called an ionophore. Ionophores allow some molecules to diffuse but not others, effectively speeding up the rate of diffusion of that molecule.
Mechanisms of tubular reabsorption include what?
Reabsorption of nutrients in the renal tubule occurs via active transport and facilitated diffusion. Amino acids, glucose and phosphates are reabsorbed at the proximal convoluted tubule via active transport. Water and sodium chloride is reabsorbed at the loop of henle via facilitated diffusion.
What is sugar broken down by fructose?
Sugar is broken down into glucose and fructose during digestion. Fructose is a simple sugar that is absorbed into the bloodstream and used for energy by our bodies. It is commonly found in fruits and honey.
