Cell Terms 2

 
 
 
 1. Molecules or ions are carried through membranes by other molecules from regions of lower concentration toward regions of higher concentration. Requires energy.

 2. Molecules are forced from regions of higher pressure to regions of lower pressure. Requires no energy.

 3. The cell organelle that releases energy from food molecules and transform energy into a usable form. Site of aerobic respiration.

 4. Molecules moved through a membrane by carrier molecules from a region of higher concentration to one of lower concentration. Requires no energy.

 5. Water molecules moving from region of higher concentration toward regions of lower concentration through a selectively permeable membrane. Requires no energy.

 6. This structure is the site of protein synthesis

 7. A very generic term used to describe a movement through a cell membrane that does not require cellular energy - an example is diffusion.

 8. Molecules moving from regions of higher concentration towards regions of lower concentration. Requires no energy.

 9. A very generic term used to describe a movement through a cell membrane that does require cellular energy - an example is active transport.

 10. This structure maintains integrity of the cell and controls the passage of materials into and out of the cell - made primarily of phospholipids.
