In biochemistry, enzymes are protein catalysts of the body that speeds up certain specific metabolic reactions in the body. They word in the concept of lock-and-key theory or induced fitting. These two theories are all based on the shape and size of the enzyme's active site that could accommodate the substrate. So, the main function of the enzyme is dependent on its shape. Therefore, when an enzyme undergoes denaturation, its orientation and shape changes. For example, a beta pleated sheet may change to an alpha helix orientation. As a consequence, the number and capacity of active sites changes. Hence, the enzyme becomes nonfunctional.
The presences of myelin allows an axon to conduct their signals rapidly
The species was a keystone species.
Keystone species are the species that ''hold the ecosystem together''.
They have an important role in the trophic networks (food chains) and often they can even afflict changes in the abiotic part of the ecosystem (change the composition of soil, purify the water, lower the effect of the wind etc)
Therefore, when a keystone species is removed it affects greatly the whole ecosystem.
<em>Parts of a Neuron;</em>
<u>Cell body: The "regular" part (Contains nucleus and other organelles) </u>
Axon: Sends signals to the synapse
Dendrites: Receive signals from other synapses
