Solution
The best explanation for how HIV attacks Helper T cells is option b: HIV binds to specific proteins to gain access to cells, and these proteins are expressed on helper T cells.
Here's a step-by-step explanation:
-
HIV targets cells that have CD4 surface proteins, which are most commonly found on Helper T cells.
-
The virus attaches itself to the CD4 protein and another co-receptor on the cell's surface.
-
Once attached, the virus fuses with the cell, allowing the virus's RNA and enzymes to enter the Helper T cell.
-
Inside the cell, the virus uses its own enzyme, reverse transcriptase, to convert its RNA into DNA.
-
This new viral DNA is then integrated into the cell's DNA with the help of another viral enzyme, integrase.
-
The infected cell, unaware of the viral DNA, reads it as its own and begins making new HIV proteins and enzymes, which are assembled into new viruses.
-
These new viruses then leave the cell and go on to infect other cells, repeating the cycle.
So, while options c and d are also part of the process, option b best describes how HIV specifically targets and attacks Helper T cells.

T-cell activation begins when a/n presents an antigen fragment in association with an MHC-II molecule to a helper T cell. Once activated, helper T cells can differentiate into T helper 1 cells which will activate cells and secretes IL-2 to help activate cell-mediated immunity. CD4 helper T cells may also differentiate into T helper cells for B-cell activation, or T helper or T regulatory cells for modulation of the response. An APC may also activate a CD8 T cell when the antigen is complexed with . These CD8 cells are called T cells. Activated CD8 cells will mount a direct attack on target cells through the action of , which punch holes in membranes, and , which then enter through these passageways.
