FINAL JEOPARDY Explain how enzymes lower the activation energy of a reaction but do not change the G of the reaction.

The “energy investment” phase of glycolysis requires the cell to provide this many ATP molecules.

In addition to 4 ATP molecules, glycolysis also produces two of these electron carriers.

These carbon-based products of glycolysis are oxidized prior to entering the citric acid cycle in aerobic organisms.

In anaerobic respiration, glycolysis can be incompletely oxidized to this molecule. Can you feel the burn?

Glycolysis takes place in the cytoplasm, evidence that supports this evolutionary history of respiration.

The presence of this molecule activates the transport of pyruvate into the mitochondria.

This phase of aerobic respiration produces the greatest amount of ATP.

Glucose is fully oxidized into this molecule by the end of the citric acid cycle.

ATP synthase can phosphorylate ADP molecules due to this type of force.

The transfer of electrons from glucose to, ultimately, oxygen, occurs in this sequence of molecules.

Plants living in hot or dry climates often have this adaptation that conserves water.

This process in C4 plants is a variation on the Calvin cycle in which excess oxygen is fixed to produce small amounts of carbon dioxide.

C4 and CAM plants both fix carbon into these molecules that later enter the Calvin cycle.

While C4 plants spatially separate the carbon fixation phase from the rest of the Calvin cycle, CAM plants separate the cycle in this way.

The carbon fixation phase of C4 photosynthesis takes place in the mesophyll cells, while the rest of the Calvin cycle takes place here.

Enzymes catalyze chemical reactions by lowering this of the reaction.

Pepsin is an enzyme found in the stomach Pepsin is an enzyme found in the stomach. Lowering the pH of a pepsin-mediated reaction would do this to the reaction rate.

Enzymes can catalyze reactions by providing this in the active site, away from the rest of the aqueous environment.

This type of regulation occurs when a molecule binds to an enzyme somewhere other than the active site.

The production of ATP by ATP synthase slows the production of pyruvate by enzymes in glycolysis, an example of this kind of feedback.

This photosystem captures sunlight using a special chlorophyll a molecule also known as P700.

This molecule is split by light energy to produce oxygen gas in Photosystem II.

In the light reactions, ATP is produced by this type of phosphorylation.

Electrons can flow in this manner to produce additional ATP for the light-independent reactions.

The proton gradient required to produce ATP accumulates in this location of a thylakoid.

The light-independent reactions, or Calvin cycle, take place in this part of a plant cell.

This phase binds this molecule to RuBP to begin the Calvin cycle.

C4 plants fix carbon using PEP Carboxylase, but C3 plants use this enzyme instead.

The reduction phase gains electrons from this electron carrier.

This last phase of the Calvin cycle is critical to the continuation of glucose production by the chloroplast.
