Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities. It stimulates muscle contraction, creates an awareness of the environment, and plays a major role in emotions, memory, and reasoning. To do all these things, cells in nervous tissue need to be able to communicate with each other by way of electrical nerve impulses. The cells in nervous tissue that generate and conduct impulses are called neurons or nerve cells. These cells have three principal parts: the dendrites, the cell body, and one axon.
Green turtles live in Tropical Ocean Waters they are affected by climate change, because sea levels rise and stronger storms will erode and destroy there beach habits.
Enzymes are biological catalysts that speed up biochemical reactions.
A substrate is the molecule that the enzyme acts upon and converts to product.
An active site is the part of the enzyme where the substrate binds to it. Active sites contain a specific amino acid sequence and conformation which make it easy for the substrate to bind.
Enzymes are stringently substrate specific i.e. only a certain substrate can fit in and bind to the active site of a specific enzyme, just like only one key can fit into a specific lock.
