Answer:
A change in pH can change the ionization of the side groups of basic and acidic amino acids of proteins., It is important to remember that these charges of are importance in stabilizing a protein secondary and tertiary structure and consequently affects its function. Changing these charges alters these interactions and disturbs protein loops such as beta-sheets and alpha-helices. This can change the structure of a proteins enzyme’s active site and cause it to fail to bind to a substrate or catalyze a reaction.
After holding the weight for so long, the muscle would get tired, in an effort to tell the brain to stop holding the weight because the muscle fibers cannot handle it any more. Lactic acid is a by-product during muscle contraction that leads to the pain.
<span>This statement is true. The muscle fiber membranes and neurons are separate by the synaptic cleft, sometimes called a synaptic gap. At each neuromuscular junction these fluid filled pockets keep things separated in order to transmit nerve impulses through a neurotransmitter.</span>
Answer:
I'm not sure what is unclear but I can try to help...
Explanation:
So the group is the number at the top and is verticle. So H,Li,Na, and K share the same Group, 1.
The period is the number at the side and is horizontal. Soo H and He are Period 1.
Now using this information we can find the specifics of each element.
Chlorine, for example, is Group 17A and Period 3 because it matches those.
Let me know if you need further explanation :)
