Answer:
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
Explanation:
This is the chemical formula for photosynthesis. Instead of just saying "Energy," however, it should specify solar energy, or light energy. Photosynthesis is the process of capturing solar energy and converting it to chemical energy.
Answer: Neutral
solution
Neutral solution
have equal number of hydrogen ions and hydroxyl ions in a solution. Its pH is
naturally equal to 7 and the charge in that solution is neutral since the
concentrations are equal. In the event that the concentration is unequal, the
solution would have had a positive or negative charge.
Additionally, acidic
solutions have more hydrogen ions than hydroxide ions while an alkaline solution
contains more hydroxide ions than hydrogen ions.
