Denaturing a proteins causes a change in the shape of an enzyme. *
True or
False

True

Explanation:

Denaturing is a process in which protein looses its shape. Due to loss of shape (structure), protein also looses its function. This change in shape is due to change in temperature or pH of the protein.

Due to high temperature the shape of active site gets distorted due to which it becomes non functional. Change in active site of enzyme will  change shape of the enzyme and make it unfit for the substrate/reaction.

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.
