Why heart disease is not an infectious disease?<br><br><br> I need help please
Sidana [21]

Answer:

The old idea that coronary heart disease is an infectious disease has gained popularity in recent years, and both viral and bacterial pathogens have been proposed to be associated with the inflammatory changes seen in atherosclerosis. Herpes group viruses, notably cytomegalovirus and herpes simplex type 1, have been associated with atherosclerosis and restenosis. Helicobacter pylori and dental infections have also been linked to atherogenesis, but the evidence seems to favor a respiratory, obligatory intracellular bacterium, Chlamydia pneumoniae. The association was originally found in seroepidemiological studies, but the actual presence of the pathogen in atherosclerotic lesions has been repeatedly demonstrated, and during past year the first successful animal experiments and encouraging preliminary intervention studies were published. The causal relationship has not yet been proven, but ongoing large intervention trials and continuing research on pathogenetic mechanisms may lead to the use of antimicrobial agents in the treatment of coronary heart disease in the future.

If you know the answer to this question please help!! ASAP I will give brainiest!
sleet_krkn [62]

Answer:

The answer is "Photosynthesis creates glucose (sugar) which is used in cellular respiration."

Explanation:

Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water. While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration. We breathe in that oxygen, which is carried through our blood to all our cells. In our cells, oxygen allows cellular respiration to proceed. Cellular respiration works best in the presence of oxygen. Without oxygen, much less ATP would be produced.
