question 6
5 pts

1. which cellular organelle is the site of aerobic

cellular respiration?
chloroplast
golgi apparatus
mitochondria
lysosomes

Explanation:

• Question 5: Cellular respiration has three main stages. Glycolysis breaks down glucose. The Krebs Cycle (Citric Acid Cycle) further processes the products from the preparatory reaction. The Electron Transport Chain generates a large amount of ATP. The preparatory reaction is a step - in between (pyruvate oxidation) but is not considered one of the three major independent stages in the traditional categorization of the three main stages of cellular respiration (glycolysis, Krebs Cycle, Electron Transport Chain).
• Question 6: Mitochondria are the site of aerobic cellular respiration. Chloroplasts are for photosynthesis. The Golgi apparatus is involved in modifying, sorting, and packaging proteins and lipids. Lysosomes are for digestion of macromolecules.

Answer:

• Question 5: Glycolysis, Kreb’s Cycle, Electron Transport Chain
• Question 6: mitochondria
