During fermentation, how do changes to a molecule of pyruvic acid
contribute to the formation of ATP?
a. They complete the oxidation of glucose to CO2, creating ATP.
b. They generate lactic acid, which cycles back through the Krebs cycle, producing 2
ATP molecules
c. They convert FADH2 to a phosphate group, which bonds with ADP
d. They produce 2 NAD+ molecules, which cycle back to fuel the glycolysis reaction,
producing 2 ATP molecules.
Mont brond ricor primarily due to the CO2 nroduced during alcoholic

Female luna moths (actias luna) attract males by emitting chemical signals that spread through the air. a male hundreds of meters away can detect these molecules and fly toward their source. the sensory organs responsible for this behavior are the comblike antennae visible in the photograph shown here. each filament of an antenna is equipped with thousands of receptor cells that detect the sex attractant. based on what you learned in this chapter, propose a hypothesis to account for the ability of the male moth to detect a specific molecule in the presence of many other molecules in the air. what predictions does your hypothesis make? design an experiment to test one of these predictions.
