Which stage of the HIV lifecycle involves the virus attaching to the host cell membrane?

Binding

Integration

Fusion

Reverse Transcription

Answer and Explanation

The Correct Answer is A

A. Binding is the initial step where the HIV virus attaches to the CD4 receptor on the host cell's surface. This interaction is crucial for the subsequent entry of the virus into the host cell.
B. Integration occurs later in the lifecycle, after the virus has entered the host cell and its RNA is converted to DNA.
C. Fusion refers to the process where the viral envelope fuses with the host cell membrane to allow entry into the cell, which follows the binding stage.
D. Reverse Transcription is the process of converting viral RNA into DNA after the virus has entered the host cell, and is not involved in the attachment phase.

Correct Answer is B

Explanation

A. In the assembly stage, other proteins and enzymes are involved in the packaging of viral components into new virions, not integrase.
B. During the integration stage, integrase is essential as it inserts the newly formed viral DNA into the host's genome, enabling the virus to utilize the host's cellular machinery for replication.
C. Integrase does not participate in the entry stage; this stage is facilitated by other proteins that aid in the fusion of the virus with the host cell membrane.
D. Integrase is not involved in reverse transcription; that process is facilitated by the enzyme reverse transcriptase, which converts viral RNA into DNA.

A. "Distributive shock occurs due to increased systemic vascular resistance." B. "Distributive shock occurs due to systemic vasodilation." C. "Distributive shock occurs due to loss of myocardial contractility." D. "Distributive shock occurs due to loss of blood volume."

Correct Answer is B

Explanation

A. Increased systemic vascular resistance is typically associated with hypovolemic or cardiogenic shock, not distributive shock.
B. Distributive shock is characterized by systemic vasodilation, which leads to a decrease in systemic vascular resistance and results in inadequate tissue perfusion despite normal or increased cardiac output.
C. Loss of myocardial contractility is related to cardiogenic shock, not distributive shock.
D. Loss of blood volume is a characteristic of hypovolemic shock, whereas distributive shock occurs even when blood volume is normal due to vasodilation.
