Enzymes catalyze reactions by lowering the activation energy of the reaction. Enzymes are made of proteins, and therefore the answer here is B. Protein molecules.
Helium makes very light than hydrogen

about 50-75% due to the fact the mom has 2 dominant genes for flight
Answer:
B. A film of food wrap
Explanation:
The membrane is supposed to keep the contents safe inside .Not many things can enter inside and almost nothing can come outside, this being the selectively permeable nature of the membrane.
The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell. And that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell. Another is that the membrane of the cell, which would be the plasma membrane, will have proteins on it which interact with other cells. Those proteins can be glycoprotein, meaning there's a sugar and a protein moiety, or they could be lipid proteins, meaning there's a fat and a protein. And those proteins which stick outside of the plasma membrane will allow for one cell to interact with another cell. The cell membrane also provides some structural support for a cell. And there are different types of plasma membranes in different types of cells, and the plasma membrane has in it in general a lot of cholesterol as its lipid component. That's different from certain other membranes within the cell. Now, there are different plants and different microbes, such as bacteria and algae, which have different protective mechanisms. In fact, they have a cell wall outside of them, and that cell wall is much tougher and is structurally more sound than a plasma membrane is.
Answer:
Carbon dioxide is a significant metabolite for each living creature. It is a soluble compound that makes it simple to diffuse all through the cell. In contrast to carbon dioxide, bicarbonate needed to be transported. The response of CO2 and water as reactants to produce hydrogen and bicarbonate in the solution. This significant reaction is effortlessly kept up with the activity of carbonic anhydrase. The transformation of bicarbonate into CO2 and the other way around encourages bicarbonates transport into the cell just as trapping of CO2 in the cell.
This response is gradually continuing in physiological pH, so life forms produce enzyme as an enhancement of reaction speed. Contingent upon what is required, the active site of this catalyst can exist in two structures a high pH structure that is active in the hydration of CO2 and a low pH that is active in the dehydration of bicarbonate. For the best result, the temperature of equilibrium is significant.
Since the ideal temperature for the enzyme's response is in the scope of 35 to 40 degrees Celsius, the best temperature worth would be 37 degrees. In this manner, the arrangement for an examination would be taking off 5 examples warmed to correct degrees in the scope of 35 to 40, with sufficient measure of catalyst and watching the velocity of response and how quick will item shows up.
