nuclear charge is always positive, because there are only protons in the nucleus, and protons are always positive.
But this is in general, because you have not mentioned the ion name.
Catalysts lower the activation energy for reactions<span>. The lower the activation energy for a </span>reaction<span>, the faster the rate. Then </span>enzymes speed up reactions<span> by lowering activation energy. Many </span>enzymes<span> change shape when substrates bind.</span>
Answer:
Facilitate diffusion by using a transporter
Explanation:
Facilitate diffusion is a type of transport in which a transporter protein is used to transport the molecule across the cell membrane along its concentration gradient. As the movement is along the concentration gradient and does not require energy so it is a type of diffusion.
Glucose travels in the cell by facilitating diffusion because it requires transporter to move across the cell along the concentration gradient. In facilitating diffusion the rate of transport in high than simple diffusion.
