Bioreactor Processes and Functions

The video tutorial explains the process of using bioreactors to cultivate cells for producing biologic molecules. It covers the conditions necessary for cell growth, the role of bioreactors, and the process of drug secretion and purification. The tutorial also discusses scaling production, quality control, and the importance of monitoring and maintaining stability in bioreactors.

What is the primary function of the big motor in the bioreactor?

• To filter the cells

• To cool the cells

• To blend and agitate the cells

• To heat the cells

What is essential for cells to divide and grow in a bioreactor?

• High acidity

• Low oxygen levels

• Correct pH and nutrients

• Absence of nutrients

What type of molecules does Biogen produce using cell culture?

• Metal alloys

• Simple chemical compounds

• Synthetic fibers

• Biologic molecules

How are cells modified to produce desired molecules?

• By changing their color

• By reducing their number

• By altering their genome

• By increasing their size

What is the purpose of purifying the cell mix?

• To remove all proteins

• To eliminate unwanted cells and proteins

• To increase cell size

• To add more nutrients

What is a major challenge when scaling up the production process?

• Increasing the acidity

• Reducing the number of cells

• Ensuring the chemical environment is consistent

• Maintaining the same temperature

Why is stability important in delivering the molecule as medicine?

• To ensure it tastes good

• To maintain its therapeutic effect

• To change its color

• To make it heavier

What role do proteins play in therapeutic functions?

• They perform healing functions

• They act as a barrier

• They change the color of cells

• They reduce cell size

What is monitored constantly inside the bioreactors?

• The color of the solution

• The pH and dissolved oxygen levels

• The size of the cells

• The weight of the bioreactor

What is the significance of the chemical environment in medicine delivery?

• It reduces the medicine's size

• It changes the color of the medicine

• It ensures the medicine is stable and effective

• It makes the medicine heavier
