Exam 9: Metabolism

In the total process of glycolysis followed by aerobic cellular respiration in bacteria, substrate level phosphorylation produces a net of ________ ATP while the oxidation of NADH and FADH₂ produces ________ ATP.

As pyruvate is oxidized to produce acetyl-Co A, what other products are produced? (Select all that apply)

What is the correct sequence of the seven events in the light reactions of photosynthesis? 1-ATP Synthase produces ATP 2-H₂O is split producing electrons to reduce P₆₈₀ 3-the electron transport chain produces a H⁺ ion gradient 4-production of NADPH 5-P₆₈₀ reaction center is oxidized when an excited electron is ejected 6- P₇₀₀ is reduced by an electron from P₆₈₀ 7-absorbsion of a photon in pigments of photosystem II

Why is carbon dioxide a key molecule in the light-independent (dark) reactions of photosynthesis?

The enzyme that uses the energy released from a H⁺ ion gradient to phosphorylate ADP making ATP.

________ are algal accessory pigments that form a globular structure that absorbs photons of different colors and funnels the energy to adjacent chlorophyll a molecules.

Glycolysis followed aerobic respiration is ________ times more efficient than glycolysis and fermentation because of the increase in the net number of ATP produced.

During the breakdown of one glucose to CO₂ and H₂O, how many pyruvate molecules are oxidized between glycolysis and the citric acid cycle?
