Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the primary pathway?Aerobic respiration involves glycolysis, the Krebs cycle, and oxidative phosphorylation
2. What is the ATP yield (aerobic)?Approximately 30-32 ATP molecules per glucose molecule
3. What is cellular respiration and why is it important for our body?Cellular respiration is the process that turns food into energy. It helps cells get the power they need to work and keeps the body running. It is used by almost all living things.
4. How does the body get energy from glucose during cellular respiration?The body breaks down glucose into smaller parts. This releases energy that is stored in molecules called ATP, which cells use to do their jobs.

Glycolysis: The initial breakdown of glucose into pyruvate, occurring in the cytoplasm.
Krebs Cycle (Citric Acid Cycle): A series of reactions in the mitochondrial matrix that oxidizes acetyl-CoA, producing ATP, CO2, and electron carriers.
Oxidative Phosphorylation: The process on the inner mitochondrial membrane where electron transport and chemiosmosis generate the majority of ATP.
