Answer
Smoking cigarettes negatively impacts cellular respiration.
Solution
a
Carbon monoxide (CO) from cigarette smoke binds to hemoglobin more effectively than oxygen, reducing oxygen transport to cells
b
Nicotine and other chemicals in cigarettes can damage the mitochondria, impairing ATP production
c
Smoking increases oxidative stress, leading to cellular damage and reduced efficiency of the electron transport chain
Key Concept
Smoking reduces oxygen availability and damages cellular components involved in respiration.
Explanation
The presence of carbon monoxide and other harmful chemicals in cigarette smoke interferes with oxygen transport and mitochondrial function, leading to decreased ATP production and increased oxidative stress.
