In your respiration packet, answer the six questions on page one.
Warm-up
The “A” in ATP stands for Adenosine. It is built by Adenine and Ribose. The “T” stands for Tri-The “P” stands for Phosphate.
Review of warm-up
3 Phosphates are present in one ATP
molecule.
How would you represent the equation in which ATP becomes ADP?
ATP ADP + PiReactant Products
• With a neighbor, fill in the steps in this cycle of Photosynthesis and Respiration.
• We will check your answers when you are done!

What is the net gain of energy in
Glycolysis?
• ATP = + 2
• NADH = + 2
Moving on to the Krebs Cycle
• Enjoy this video clip, and jot down a summary of Krebs’ and Chance’s research.
• Pay attention to the significance of both scientist’s discoveries.

FADHFADH2
How much energy did the Krebs Cycle produce?
NADH = +3
ATP = +1
FADH2 = +1
• But there were two molecules of Acetyl CoA that went into the Krebs Cycle…
• How many would be produced in this case?
+6
+2
+2
Where is the energy?
• So far, most of the usable energy from the original glucose molecule is stored in
and
• Where will most of the ATP be made?
