What is the implication of non-polar molecules being fatser than plar molecules through the cell membrane?
The implication of non-polar molecules being faster than polar molecules through the cell membrane is seen in the transport of essential molecules like glucose. This is made possible through the gradients that are established as a result of this.
How insulin signals a cell to take in glucose from the blood?
The insulin binds to insulin receptors on the surface of muscle or liver cells. This opens up little holes in the cell membrane called glucose transporters. Glucose flows through the glucose transporter due to the concentration gradient of glucose being higher in the extracellular environment. This is called diffusion. The membrane only stays permeable (open) to glucose so long as there is insulin bound to the receptors on the cell surface. Eventually the insulin is released and the glucose transporter closes. The cell then starts to digest the glucose via complicated processes called glycolysis and oxidative phosphorylation.
When is active transport needed?
When large materials are being transported through the membrane
What kind of transport is used by a cell membrane to speed up the intake of glucose when needed?

What does it mean when cell membrane is selectively permeable?
The cell membrane will only allow certain molecules access. For example, glucose molecules are too large to pass through the cell membrane without undergoing endocytosis, but water molecules can easily pass through the cell membrane.

Why is the cell membrane described as being a selective barrier?
Cell membranes are selective barriers because they only let certain substances pass through and therefore ensures the cells survival.
Does light effect euglena?
Light affects euglena by inhibiting growth. Specifically light inhibits glucose consumption and growth on glucose containing mediums. The permeability of the cellular membrane being modified is a possible explanation.

What complex carbohydrate passes out of the body through the GI tract without being digested?
Glucose, if you're a diabetic with a rectal bleed.
What process is used to move sugar molecules across a cell membrane?
I do believe that the answer is facilated diffusion.

What problem would the first route pose for Odysseus?
The first route posed the problem of not being able to get through.
What does selective permeability mean what is responsible for the selective permeability of the plasma or cell membrane?
When a cell's membrane is permeable, it means that only certain proteins and other molecules can go in and out of the porous membrane, through protein pumps and other pathways. Some molecules stay inside the cell, while others float outside. Starches, for example, are large molecules that cannot pass through the membrane.
How is most glucose transported into cells?
Passive transport is the kind of movement Êwhen glucose enters a liver cell through a protein channel. It does not require an input of chemical energy being driven by the growth of entropy in the system.Ê
