Research point 1 Protein

hemoglobin

It is composed of protein and heme and acts as a carrier.

2. It is easy to combine with CO but difficult to separate. It can no longer be combined with oxygen, causing tissue cells to become hypoxic and suffocate to death.

Toxic substances in cigarette smoke

Cigarette smoke contains hundreds of toxic substances, including carbon monoxide.

Denaturation of proteins

Formaldehyde, alcohol, high temperature, heavy metals, etc.

Formaldehyde, alcohol, heavy metals, high temperature and other conditions

Destroy the structure of proteins and cause them to deteriorate. thus causing cell death.
