Mitochondria are the powerhouses of the cell and contain enzymes needed for aerobic respiration.

The inner membrane of the mitochondrion is folded into cristae which hold the enzymes needed in energy transformations to make ATP. Lysosomes are the "garbage disposals" of the cell and contain digestive enzymes to break up old cell components and bacteria.

Peroxisomes contain enzymes that function in the synthesis of bile acids, breakdown of. Diffusion is caused by the random motion of molecules and involves the movement of molecules from an area of greater concentration to one of lesser concentration until equilibrium is reached.

Facilitated diffusion uses membrane proteins that function as carriers to move molecules such as glucose across the cell membrane.

Osmosis is a special case of diffusion in which water moves from an area of. Tonicity A solution with the same osmotic pressure as body fluids is called isotonic; one with higher osmotic pressure than body fluids is hypertonic; one with lower osmotic pressure is hypotonic. Because of hydrostatic pressure, molecules can be forced through membranes by the process of filtration.

Blood pressure is a type of hydrostatic pressure.

Cytology and Cell Physiology

The union of the specific particle to be transported with its carrier protein triggers the release of cellular energy ATP , which in turn alters the shape of the carrier protein, releasing the particle to the other side of the membrane.

Particles that are actively transported include sugars, amino acids, and sodium, potassium, calcium, and hydrogen ions, as well as nutrient molecules in the intestines. In endocytosis, molecules that are too large to be transported by other means are engulfed by an invagination of the cell membrane and carried into the cell surrounded by a vesicle. Three forms of endocytosis are pinocytosis, phagocytosis, and receptor-mediated endocytosis.

Pinocytosis is a form of endocytosis in which cells engulf liquids. Phagocytosis is a form of endocytosis in which the cell takes in larger.

Receptor-mediated endocytosis allows the cell to take in very specific. If you don't receive any email, please check your Junk Mail box.
