30) is B bec it goin from a low to high concentration every time that happens it requiers ATP.
31)B bec think of a enzyme as a key and a lock only one key will work with one lock and not others. So you see B and the black shape on top of it fits perfectly with. B . Another shape would not. So if it was a different shape the enzyme would not recognize it. The key would not fit the lock.
32) is A it pointing arrows out of the cell so everthing need to go out cell A has more insde then out so think ATP as a force pushing it out. And B there more in then out so it can move out easily:
1.Height- how tall someone is in the 1800 vs 2019
2. Bone structure-density
3.Life expectancy-
Protein folding is the physical process by which a protein chain acquires its native 3-dimensional structure, a confirmation that is usually biologically functional, in an expeditious and reproducible manner. It is the physical process by which a polypeptide folds into its characteristic and functional three-dimensional structure from random coil. Each protein exists as an unfolded polypeptide or random coil when translated from a sequence of mRNA to a linear chain of amino acids. This polypeptide lacks any stable (long-lasting) three-dimensional structure (the left-hand side of the first figure). As the polypeptide chain is being synthesized by the ribosome, the linear chain begins to fold into its three-dimensional structure. Folding begins to occur even during translation of the polypeptide chain. Amino acids interact with each other to produce a well-defined three-dimensional structure, the folded protein (the right-hand side of the figure), known as the native state<span>.</span>
Answer:
Because this offers a control for your experiment.
Explanation:
If you are testing the effects of an enzyme, you need to have a control to compare your results with to see if the enzyme is truly what is causing the phenomenon.
I think it’s how they are inside and get stuck
