Question

Place the following events in order for the activation process of our T Cells and B Cells

A)T Cells secrete cytokines
B)T Cells become activated
C)Antibodies get secreted
D)Cell displays antigen on its surface
E)B Cells become activated

Answer 1

T and B cell activation involves a cell presenting an antigen, leading to T cell activation, cytokine secretion by T cells, activation of B cells, and finally, secretion of antibodies by plasma cells.

Step-by-step explanation:

The activation process of T cells and B cells in an immune response involves a specific sequence of events. Here are these events placed in the correct order:

1. Cell displays antigen on its surface
2. T Cells become activated
3. T Cells secrete cytokines
4. B Cells become activated
5. Antibodies get secreted

Initially, a cell (a B cell or antigen-presenting cell) displays an antigen on its surface. When a T cell encounters this antigen, it becomes activated. Following the activation, the T cell secretes cytokines, which are critical signaling molecules in the immune system. These cytokines then help B cells to become activated. Once activated, B cells proliferate and mature into plasma cells. Plasma cells are the cells responsible for secreting antibodies, which specifically target the antigens to neutralize or mark them for destruction.
