Scientists grow three cultures of yeast cells in different conditions. They measure the number of ribosomes in each cell and the amount of protein each cell makes per minute.
| Culture | Number of ribosomes per cell (thousands) | Protein made per cell per minute (arbitrary units) |
|---|---|---|
| A | 200 | 12 |
| B | 400 | 24 |
| C | 600 | 36 |
Using the data, explain how the number of ribosomes affects protein production. Then predict the protein made per cell per minute by yeast cells with 800 thousand ribosomes per cell, assuming the pattern continues.
