The answer is (d) an enzyme.
Enzymes are biological catalysts, which means they decrease the amount of activation energy need to start a reaction, therefore speeding up the rate of the reaction. They are part of the protein macromolecule group. Without them, our body would not process things fast enough for us to live.

nata0808 [166]

Answer:

plant cell

Explanation:

The Golgi apparatus is a cell organelle responsible for modifying, sorting and packaging proteins and lipid molecules into vesicles (i.e., Golgi vesicles) for their delivery to targeted cell sites. A plant cell can contain many -even hundreds- of Golgi apparatus. During cell division of plant cells, Golgi vesicles combine at the metaphase plate in order to form a structure called phragmoplast. Subsequently, the cell plate formed by phragmoplast vesicles grows from the center to the cell walls. Finally, the vesicle membranes fuse to form a plasma membrane that divides the plant cell into two cells.
