Cell Membrane
The main function of the cell membrane is this.
Control what goes in/out of the cell
These two adjectives describe the type of molecules that move through the phospholipid bilayer during simple diffusion.
small, nonpolar
Cellular respiration occurs in this organelle in eukaryotic cells.
Mitochondria
Things naturally diffuse across the cell membrane with the concentration gradient, which means they go from this concentration to this concentration.
From H con. --> L con.
In the case of molecules, like sugar, that are too large and polar to go through the cell membrane using the traditional method, they must diffuse through one of these.
protein channel
Photosynthesis utilizes the energy from this to make its products.
The Sun (sunlight)
Phospholipids are a special kind of lipid that are comprised of a hydrophilic, phosphate head and two hydrophobic, nonpolar these.
fatty acid tails
If those large, polar molecules have to be taken in or out of the cell against the concentration gradient, they would go through one of these instead.
protein pump
The purpose of cellular respiration is to make 36-38 molecules of this, which stores energy for the cell until needed.
ATP (Adenosine Triphosphate)
Although there are proteins along the cell membrane that aid in cell transport (amongst other things), the main portion of the cell membrane is this semipermeable barrier.
Phospholipid Bilayer
When the Golgi apparatus sends vesicles out of the cell at the end of the endomembrane system, it is an example of this process.
Exocytosis
The products of photosynthesis are glucose, which is the organism's source of food, and this molecule.
Oxygen (O2)
These are the proteins along the cell membrane that aid in the transport of water molecules.
When cells reach the end of their life cycle, they are absorbed by other cells in a process called phagocytosis to be disposed of. This is an example of this process.
Endocytosis
When respiration utilizes oxygen to complete its process, we say it is this kind of respiration.
