Understanding T Cells and the Immune Response

What is the main job of the 'fighters' in the metaphorical scenario described in the video?

• To entertain the crowd

• To protect the room from invaders

• To organize the people in the room

• To provide medical assistance

What is the role of antigen-presenting cells in the immune response?

• They produce antibodies

• They create new pathogens

• They present antigens to T cells

• They destroy pathogens directly

How many different receptors are estimated to be in the human body?

• 100 million

• 100 billion

• 100 trillion

• 100 thousand

What are the two main domains of T cell receptors?

• Alpha and beta chains

• Constant and variable regions

• Antigen and antibody

• Nucleus and cytoplasm

What determines the sequence of a T cell receptor?

• The cell's environment

• The cell's RNA

• The cell's age

• The cell's DNA

What is the significance of the variable region in T cell receptors?

• It stores genetic information

• It controls the cell's movement

• It allows recognition of diverse antigens

• It determines the cell's lifespan

What happens when a T cell recognizes an antigen?

• It leaves the body

• It changes its receptor

• It replicates and increases in number

• It becomes inactive

What is a T cell clone?

• A single T cell

• A group of T cells with the same receptor

• A T cell that has mutated

• A T cell that has been destroyed

Why are T cells crucial for the immune system?

• They transport oxygen

• They produce hormones

• They recognize and respond to pathogens

• They store energy

What is the main takeaway about T cells from the video?

• They are responsible for digestion

• They only function in the brain

• They are crucial for recognizing pathogens

• They are not important for survival
