Question

labeling cellular respiration directions: correctly label where the different steps of cellular respiration take place using the label cards. cards: you have no more cards to place! (the related image shows the structure of mitochondrion and related reaction parts, with label options like intermembrane space, electron transport chain, krebs cycle, glycolysis, matrix, inner membrane, cytoplasm, mitochondrion, and reaction name areas)

Explanation:

To label the steps of cellular respiration:

1. Glycolysis: Occurs in the Cytoplasm (area outside the mitochondrion).
2. Krebs Cycle (Citric Acid Cycle): Occurs in the Matrix of the mitochondrion.
3. Electron Transport Chain (ETC): Occurs in the Inner Membrane of the mitochondrion, with the Intermembrane Space involved in proton gradient formation.

For the diagram:

• "Area Outside Organelle" → Cytoplasm (Glycolysis location).
• "Reaction Name" (near the hexagon) → Glycolysis.
• The space between the outer and inner mitochondrial membranes → Intermembrane Space.
• The inner mitochondrial compartment → Matrix (Krebs Cycle location).
• The folded inner mitochondrial membrane → Inner Membrane (ETC location).
• The organelle itself → Mitochondrion (site of Krebs Cycle and ETC).

Answer:

• "Area Outside Organelle" → Cytoplasm
• "Reaction Name" (hexagon) → Glycolysis
• Mitochondrial intermembrane region → Intermembrane Space
• Inner mitochondrial compartment → Matrix
• Folded mitochondrial membrane → Inner Membrane
• Organelle → Mitochondrion
• "Reaction Name" (inner membrane) → Electron Transport Chain
• "Reaction Name" (matrix) → Krebs Cycle
