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.
What kind of transport is used by a cell membrane to speed up the intake of glucose when needed?
Facilitated diffusion is used by the cell membrane to speed up the intake of glucose when needed. This process involves the use of transport proteins to allow glucose molecules to pass through the membrane at a faster rate than simple diffusion.
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.
What specific molecule is being made in chloroplast?
The specific molecule being made in chloroplasts is glucose through the process of photosynthesis. This is accomplished by using light energy to convert carbon dioxide and water into glucose and oxygen.
How does the glucose get to the body cells?
Glucose is absorbed through the small intestine into the capillaries. There are millions of villi (finger-like projections) that line the inside of the small intestine to increase its surface area for absorption. Villi have a very rich blood supply, so the glucose can be absorbed quickly and the blood is taken away quickly, maintaining a steep concentration gradient for more glucose, and other food, to be absorbed.
A molecule such as glucose must use a protein channel to cross through a cell membrane?
This is correct. Glucose, being a large molecule, requires a protein channel called a glucose transporter to facilitate its passage through the cell membrane. Glucose transporters assist in transporting glucose molecules across the hydrophobic lipid bilayer of the cell membrane.

When a mixture of starch and glucose is put into a bag made from partially permeable membrane and is put in a beaker so after 20 minutes what change will take place in the contents of bag?
After 20 minutes, the glucose molecules will diffuse out of the bag through the partially permeable membrane because they are smaller in size than the starch molecules. The starch molecules, being too large to pass through the membrane, will remain inside the bag.
If one says that the clearance value of glucose is zero what does this mean?
A clearance value of zero for glucose means that no glucose is being excreted or removed from the body within the specified time frame. This could indicate a problem with glucose metabolism or kidney function, as glucose should normally be cleared from the body through urine.

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.
Why is the cell membrane described as being a selective barrier?
The cell membrane is described as being a selective barrier because it controls the movement of substances in and out of the cell. It allows some molecules to pass through while blocking others based on factors like size, charge, and solubility. This selectivity helps maintain the cell's internal environment and regulates cellular processes.
How do your cells get oxygen glucose and the raw materials that they need to respire?
Cells get oxygen through the bloodstream, where red blood cells carry oxygen from the lungs to the cells. Glucose and other nutrients are also transported through the bloodstream after being broken down from the food we eat during digestion. This process ensures that cells have the necessary raw materials to undergo cellular respiration and produce energy.
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.
