Understanding Animal Cell Culture Media

What is the primary purpose of cell culture media?

• To make the cells visible under a microscope

• To preserve cells at low temperatures

• To support cellular growth by supplying nutrients

• To provide a color indicator for experiments

At what temperature do cells optimally grow in a culture incubator?

• 20 degrees Celsius

• 37 degrees Celsius

• 25 degrees Celsius

• 45 degrees Celsius

What is the significance of the substratum in cell culture?

• It acts as a nutrient source

• It colors the media

• It regulates the temperature

• It provides a surface for cells to attach

Which component in the media acts as a carbon source?

• Amino acids

• Glucose

• Serum

• Vitamins

What is the role of buffers in cell culture media?

• To supply carbon sources

• To provide structural support to cells

• To maintain pH stability

• To act as a growth factor

What is a common use of amino acids in cell culture media?

• As a nitrogen source

• As a vitamin source

• As an energy source

• As a pH buffer

What does a yellowish color in the media indicate?

• The media requires immediate change

• The media is in optimal condition

• The pH is too high

• The media is contaminated

What does phenol red indicate in cell culture media?

• Growth factor activity

• pH level

• Temperature stability

• Nutrient levels

What does a pinkish media color indicate about CO2 levels?

• CO2 levels are too low

• CO2 levels are too high

• CO2 levels are optimal

• CO2 supply needs to be checked

Why is synthetic media preferred over natural media in laboratory research?

• It is cheaper

• It is easier to prepare

• It has less variation between batches

• It supports faster cell growth
