16. Name the three processes of aerobic cellular respiration. How many ATP’s does each process produce, and what is the total ATP produced from one glucose?

3 Processes of Cellular Respiration #ATP produced
Glycolysis 2 ATP
Krebs Cycle 2 ATP
Electron Transport Chain Up to 34 ATP
Total ATP per 1 Glucose = 38 ATP


  1. Name the two stages of photosynthesis and list the starting molecule(s) and ending molecule(s) of

Stages Starting Molecule(s) Product(s)
Light Reaction H2O, Sunlight ATP, NADPH, O2
Calvin Cycle ATP, NADPH, CO2 Glucose


  1. What is the general chemical equation of photosynthesis?

The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.


  1. When and why does our body use lactic acid fermentation?

When no O2 (or not enough) is present, because O2 is needed for Krebs Cycle.

  1. Explain how the equations for photosynthesis and aerobic respiration compare.

Products of one became the reactants of other.
