Marat540 [252]

Answer:

The options to this question is incomplete, the correct options are:

A) the citric acid cycle.

B) oxidative phosphorylation.

C) glycolysis.

D) the citric acid cycle and oxidative phosphorylation

The answer is D

Explanation:

Cellular respiration is an important metabolic process carried out by the cells of living organisms including human cells. Aerobic cellular respiration involves three main stages viz: Glycolysis, Kreb's cycle, and Oxidative phosphorylation. These three processes occur to bring about the breakdown of glucose to synthesize ATP.

Glycolysis occurs in the cytoplasm while Kreb's cycle and Oxidative phosphorylation both occurs in the matrix and intracellular membrane of the Mitochondrion respectively. Hence, a drug that causes holes in both mitochondrial membranes will affect both Kreb's cycle and Oxidative phosphorylation.

Some viruses are RNA-based—ejecting their single-stranded RNA into the cell of a host. Let's say we are dealing with this type o
kow [346]

The DNA, RNA or the RNA Polymerase of the infected cell would not be virus's primary source of heritable information because it has the ability to integrate into host cell and get itself replicated, also it causes infection so multiplication becomes necessary.

Explanation:

The virus has reverse transcriptase enzyme in them which works slightly different. It transcribes RNA into DNA and eventually gets integrated into the genome of the host. It is here the DNA in the host cell is transcribed and translated. Thus it is modelled to have RNA as genetic material.

When virus infects the living cell by a process called a lytic infection, it injects its genetic material into it to get replicated and increase its number and eventually bursts the infected cell. Since a virus causes infection, it has to increase in number so it uses its own genome to get replicated.
