<span>In cells, enzymes are proteins that are needed to lower the amount of energy required to start chemical.</span>
Enzymes are biological catalysts which accelerate chemical reactions (reactions are millions of times faster than without them). Every enzyme has an active site which binds substrates and converts them into products.
Answer:
Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.
