The organic molecules that functions to help <span>speed up biological chemical reactions would be proteins. These substances are called enzymes which are made up of proteins. Hope this answers the question.</span>
Active transport
requires energy. This is because it is going against the natural process of diffusion. Substances diffuse when their net movement is down the concentration gradient (from higher concentration to lower). Active transport is movement from lower concentration to higher. Cytosis (phagocytosis , pinocytosis) also requires energy.
A. disconformity. I hope i helped you.
