Enzymes are highly specific proteins that function best at certain pHs. A change in pH would affect its structure; too high or too low would cause denaturation. When this happens, the enzyme won’t have the correct structure to function as a catalyst. Therefore, reaction rate will slow.
Hope this helps!!
Ferromagnesian minerals are minerals that have iron or magnesium in their structure. The greater specific gravity is between 3.2 and 3.6. Some examples are pyroxene, biotite, garnet, and olvine.
Most mafic minerals are dark in color, and common rock-forming mafic minerals include olivine, pyroxene, amphibole, and biotite. Common mafic rocks include basalt, diabase and gabbro. Mafic rocks often also contain calcium-rich varieties of plagioclase feldspar.
Kathy's medical history indicates that she is suffering from Multiple Sclerosis (MS). MS is a disorder of the central nervous system (CNS) and it is mediated and triggered by the immune system. The immune system attacks and destroys the insulating myelin cover of nerve cells of the CNS, causing severe disruption of the functions of the CNS. The most common symptoms of MS include visual, motor and sensory problems.
Kathy's medical problems are related to both her sensory and her motor neurons. She suffered from loss of hearing and experienced feelings of numbness and tingling in some parts of her body. These symptoms are related to her sensory neurons. There are several different kinds of sensory neurons, depending on the stimuli that they are receiving (smell, taste, hearing, vision, temperature, mechanoreceptors etc) and they all participate in the process of sensory transduction. She also suffered from muscle weakness, which caused her inability to get out of bed and walk properly. Her motor neurons are implicated in these symptoms. Motor neurons are the nerve cells responsible for activating muscle cells.
