Answer:
The correct answer is option C, that is, increase the concentration of the enzyme.
Explanation:
Biological molecules or proteins that enhance the rate of a chemical reaction taking place within the cell are known as enzymes. These proteins play an essential part in the proper functioning of the body, as they help in the process of metabolism and digestion.
In the given case, if the enzyme gets saturated with the substrate, and is working at optimum pH and temperature, then to enhance the rate of the reaction the only thing that can be done is to enhance the concentration of the enzyme. However, further stimulation of some of the enzymes can be done with the addition of allosteric activators in the reaction, otherwise, enhancing the concentration of the enzyme is the only way.
D hurricanes makes the most sense because lightning isn't and blizzards have nothing to do with ocean waters and tornadoes only occur inland.
It’s A. Random!! I looked it up!
I am pretty sure that the answer is carbon dioxide.
Answer:
The right answer is (B) the extracted lipids cover twice the surface area of the intact red blood cells.
Explanation:
To explain this statement is necessary to take into consideration the structure of a lipid. On the first place lipids that form membranes are called phospholipids, this means they have one 'head' that is hydrophilic and a tail composed by the lipidic chain that is hydrophobic.
In a biologic context, the phospholipids form the cellular membrane. They do so by a bi-layer disposition, meaning that one the external side of the cell there is a layer of phospholipids with the hydrophilic head and in the internal side, there is a second layer of phospholipids with the hydrophilic head. The hydrophobic 'tails' are in the middle. This disposition is due to the fact that both the external and the internal environments are water based.
Therefore, since each cell has a bilayer membrane of phospholipids, when the cells are dissolved and all the lipids that used to form the membrane are put together, they will occupy twice the surface of the red blood cells.
