Separate the following molecules based on being long term storage, short term storage, or for immediate use: Glucose, polysaccharides, monosaccharides, ATP, lipids.

Long term: polysaccharides, lipids. Short term: glucose, monosaccharides.Immediate use: ATP

What are the three most common types of work that cells do? Give an example of each.

Chemical: there are many examples you can choose from; e.g., glycolysis, photosynthesis, or any other reaction that uses ATP.


Transport: active transport of molecules across membranes requires ATP (also bulk transport)


Mechanical: the movement of cilia and flagella is mechanical work that requires ATP.

What are life’s two big reactions? Compare the products of one to the reactants of the other. What do you notice?

Photosynthesis and respiration. The products of photosynthesis (glucose and oxygen) are thereactants of respiration. The products of respiration (carbon dioxide and water) are the reactants inphotosynthesis. The two reactions complement one another.

Does respiration require energy or does it release energy? Will that make it endergonic or exergonic?

Release energy. Exergonic.

NADH and FADH2 are considered electron carriers. What type of molecule are they (enzymes,coenzymes, or salts)

Coenzymes.

Glycolysis- aerobic respiration

Glycolysis – happens in the cytosol –2 ATP used but 4 produced so net gain of 2ATP – also 2 NADH are produced

Transition Step

Transition Step (pyruvate oxidation)

The citric acid cycle (Krebs Cycle)

The citric acid cycle (Krebs Cycle) – happens in the mitochondria matrix –ATP, NADH, and FADH areproduced – one glucose molecule, 2 Krebs cycles

Oxidative phosphorylation

Oxidative phosphorylation = electron transport chain + chemiosmosis happens in the mitochondria inner membrane space. Most of the ATP is produced during oxidative phosphorylation. 3 ATP are made from every NADH, 2 ATP are made from each FADH2

What are the two functions of ATP-synthase? How can the two functions explained in terms of coupled reactions?

Proton channel and an enzyme to help make ATP. Coupled reaction because pumping protons through the channel releases energy whereas making ATP from ADP requires energy.
