Answer: <u>Enzymes must have 'desired' temp. in order to properly react.</u>
Explanation:
More heat means more kinetic energy, so molecules move faster. This makes the substrate molecules more likely to collide with the enzymes' active sites. The energy of these collisions also increases, which means each collision is more likely to result in a reaction. The rate of reaction continues to increase until the enzyme reaches its optimum temperature.
Being the same species means that they can reproduce and create fertile, healthy offspring. If they are in the same species they are surely in the same family too.
