Cell Respiration Guided Inquiry

C₆H₁₂O₆ + O₂ —→ CO₂ + H₂O + ATP

What are the names of the molecules in the equation above? (name them in the same order given above)

Glucose+ Oxygen --> Carbon dioxide + water + Adenosine triphosphate (use the full name here!)

Name the 4 steps of cell respiration

Step 1: Glycolysis

Step 2: Intermediate Stage

Step 3: Citric Acid Cycle (or Krebs Cycle)

Step 4: Electron Transport Chain (ETC)

In which steps are NADH and/or FADH2 produced?

Glycolysis, Intermediate Stage, Citric Acid Cycle,

In which step is NADH and FADH2 used?

Electron Transport Chain

In which step of aerobic cellular respiration is the most ATP produced?

Electron Transport Chain

ATP is produced from ADP by a chemical process called BLANK which means adding a phosphate.

phosphorylation

Producing ATP directly in glycolysis and the citric acid cycle is called blank

substrate-level phosphorylation.

How many ATP are produced this way in the breakdown of one glucose molecule? BLANK ATP

4

Producing ATP using oxygen and high energy molecules in the electron transport chain is called

oxidative phosphorylation

How many total ATP could be made through the electron transport chain using this process?

34 ATP

Thinking about what you’ve learned above, aerobic respiration using fatty acids that are converted to Acetyl CoA will start which step of aerobic cellular respiration?

Citric Acid Cycle

Using what you know from above, how many ATP will be produced from one glucose molecule in anaerobic cellular respiration?

2

Using information from your book, what is the byproduct of anaerobic respiration?

Lactate
