CELLS-PDLZDK

Mammalian cell cultures are typically grown in a medium that is supplemented with antibiotics and fetal bovine serum.

Which of the following best explains why fetal bovine serum is critical for the continued growth of cells in culture?

A

The fetal bovine serum contains antibodies that will help protect the cell culture from contamination.

B

The fetal bovine serum contains high levels of glucose that can be used as an energy source to fuel cell growth.

C

The fetal bovine serum contains growth factors that stimulate the cells to divide.

D

The fetal bovine serum contains electron carriers that are critical for cellular respiration, which fuels cell growth.
