Organelles involved in energy conversion are A. MITOCHONDRIA AND CHLOROPLASTS
ribosomes - protein builder
SER - production and metabolism of fats and steroid hormones
golgi apparatus - process and package macromolecules (proteins and lipids)
D. ACTIVE TRANSPORT is a means of particle transport that requires input of energy from the cell.
In diffusion, particles tend to move from an area where they are more concentrated to an area of lesser concetration.
*facilitated diffusion does not require additional energy.
Osmosis is an example of facilitated diffusion.
