Answer:
Pyruvate kinase is the important enzyme that catalyzes the conversion of phosphoenol pyruvate into the pyruvate in the glycolysis cycle. This step generates the ATP molecule.
The regulation of the pyruvate kinase is done by the allosteric regulation and fructose 1,6 biphosphate activates the pyruvate kinase. This regulation is important as it control the metabolites present in different organs. The metabolites like fructose, galactose enters in the glycolysis from the liver after the particlar step of glycolysis.
1. This simply means particles will move from areas with a lot of the same particle to areas with less of that particle to even out the concentration of the particle across the entire solution.
2. Two examples are factors that affect diffusion are temperature and surface area. Basically, as temperature increases, so does the rate of diffusion, and as surface area decreases, so does the rate of diffusion.
3. Facilitated transport occurs when a molecule is too large or cannot cross the membrane freely through a channel protein. A vesicle, formed by the plasma membrane, will form around the molecule and slowly make its way through the membrane by interacting with the non polar tails of the phospholipid bilayer.
4. Osmosis is the diffusion of water across a membrane. Basically, this means water moving into and out of cells with its concentration gradient.
5. A solution is isotonic relative to a cell if the concentration of a particular particle is equal both in the solution and in the cell. A solution is hypotonic if the concentration inside the cell is less than the concentration of the solution, which will cause the cell to swell as fluid enters the cell. A solution is hypertonic if the concentration inside the cell is greater than the concentration of the solution, which will cause the cell to shrink as particles leave the cell. These concepts dictate whether or not diffusion will occur and, if it does, which direction it will occur in.
Hope this helps! :)
The importance of mitosis to living organisms living organisms is that it allows organisms to grow in size and repair themselves.<span> When an organism grows, its cells do not grow larger; they divide to make more of themselves through the process of mitosis, or cell division.
I hop that I helped have a great day

Answer:
Epistasis describes how gene interactions can affect phenotypes. Did you know that genes can mask each other's presence or combine to produce an entirely new trait? In his dihybrid crosses with pea plants, Gregor Mendel simultaneously examined two different genes that controlled two different traits.
