Answer:
It is the portion of internal energy that can be transferred from one substance to another
If the temperature is too high, it can alter the structure of the enzyme and make it unable to bind to the substrate. But, if the temperature is too low the chance for the enzyme to collide with the substrate will be lower too. The enzyme works best in the highest temperature before its structure changed.
The data from the experiment should look like a bell. There is an optimal temperature for the enzyme and increasing/decreasing from that temperature will result in reduced reaction speed.
Mitochondria are the powerhouses of the cell because they break the chemical bonds of glucose to release energy that our cells use to do work and perform chemical reactions.
