Enzymes catalyze reactions by decreasing this
The process where substances move from an area of high
concentration to an area of low concentration
If a toxin, such as a bacterial toxin, destroys ribosomes, this will be the cellular activity first
affected
This is the organelle involved with packaging materials for
export
With a high concentration of chloride ion on the outside of
the cell and a low concentration on the inside, it will enter the
cell by this process.
This is the Theory that chloroplasts and mitochondria were once autonomous cells
before they were incorporated into eukaryotic cells
This is the location of glycolysis in cells

If as we age, the concentration of antioxidant enzymes decreases, our ability to fight the
effects of oxidizers in our body decreases. If our body shows a 50% decrease in
concentration by age 40, should we expect to see drastic effects of oxidation according to
the figure below?
