Verified step by step guidance

1. Identify the mitochondrion structure in the image.
2. Label the cytoplasm outside the mitochondrion where glycolysis occurs.
3. Label the mitochondrial matrix where the citric acid cycle (Krebs cycle) takes place.
4. Label the inner mitochondrial membrane where the electron transport chain is located.
5. Ensure each label is clearly marked and corresponds to the correct location within or outside the mitochondrion.

Key Concepts

Glycolysis

Glycolysis is the metabolic pathway that converts glucose into pyruvate, producing a small amount of ATP and NADH in the process. This occurs in the cytoplasm of the cell and is the first step in cellular respiration, providing the necessary substrates for the citric acid cycle and subsequent energy production.

Citric Acid Cycle

The citric acid cycle, also known as the Krebs cycle, takes place in the mitochondria and is a key component of aerobic respiration. It processes acetyl-CoA derived from carbohydrates, fats, and proteins, generating ATP, NADH, and FADH2, which are crucial for the electron transport chain and overall energy production.

Electron Transport Chain

The electron transport chain (ETC) is a series of protein complexes located in the inner mitochondrial membrane. It utilizes electrons from NADH and FADH2 to create a proton gradient, which drives ATP synthesis through oxidative phosphorylation. This process is essential for the efficient production of ATP in aerobic organisms.
