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.
