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?
Fructase breaks down sugar. Fructose is the name of the sugar. You found the answer via a typo :)
What helps molecules diffuse across membrane through transport proteins?
A process known as passive transport helps molecules to diffuse across a membrane. Passive transport does not involve the use of chemical energy, unlike active transport does.

How does all the material required by the cell get into the cell?
Via endocytosis, active transport and facilitated passive transport and diffusion.
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 is diffusion assisted by special protein molecules which bind to substances that diffuse across membranes?
facilitated diffusion
What characteristic is shared by simple diffusion and facilitated diffusion?
They both diffuse the particles in order to reduce the boner.
What happens in the process of facilitated diffusion In what part of the membrane does it take place?
In facilitated diffusion, substances will still diffuse down their concentration gradient but they make use of a transport protein.
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.
