Gluconeogenesis is a
metabolic pathway that results in the generation of glucose from non-carbohydrate
molecules, from breakdown of amino acids or fatty acids and from other steps in
metabolism that include pyruvate and lactate. This pathway is one of several
main mechanisms used by humans and many other animals to maintain blood glucose levels<span>, avoiding low
levels of blood glucose.</span>
The biosphere
(I am pretty positive thats the answer)
Explanation:
you just need to know that :
population density = no of ( what is asked) / land area.
The answer is A. any sample of human cells such as a blood smear or bits of skin.
On the inside side of the system, there are non-polar amino acids that can make bonds with the hydrophobic tails of the phospholipids found inside cell membrane structures.
An unusual combination of amino acids forms a channel protein, which embeds in the cell membrane and creates a hydrophilic channel for water and small, polar ions. Each channel protein, like all transport proteins, has a size and shape that keeps out all but the most particular molecules. A hydrophilic area forms in the core of the majority of channel proteins, which are composed of several similar protein subunits. Although the amino acids exposed within the hydrophobic cell membrane are hydrophilic on the inside, they are also non-polar. As a result, the protein is better able to bind to the membrane. Polar forces would drive the protein back into place if it tried to escape the membrane.
