Question

activity 1: warm up
read the following question and answer in complete sentences.
what do you notice about the path oxygen molecules take inside the metabolism simulation of a healthy body? describe in detail.

Explanation:

In a healthy body's metabolism simulation, oxygen molecules enter via respiration (lungs), diffuse into blood (binding to hemoglobin in red blood cells), travel to tissues, diffuse into cells, enter mitochondria, and participate in cellular respiration (like aerobic respiration, producing ATP, CO₂, and water).

Answer:

In the Metabolism Simulation of a healthy body, oxygen molecules first enter the body through the respiratory system (e.g., lungs). They then diffuse into the bloodstream and bind to hemoglobin in red blood cells. The blood carrying oxygen is transported to various body tissues. From the blood, oxygen diffuses into the cells of these tissues. Inside the cells, oxygen moves into the mitochondria, where it participates in cellular respiration (such as aerobic respiration) to help break down nutrients (like glucose) and produce energy (ATP), along with carbon dioxide and water as by - products.
