Allosteric feedback inhibition is best described by which of the following statements?
A molecule binds to an enzyme at a site other than the active site, causing a change in enzyme activity.
A substrate binds directly to the active site of an enzyme, increasing its activity.
An enzyme is permanently deactivated by a covalent modification at the active site.
A product of a reaction binds to the active site, blocking substrate binding.

Differentiate between oxidative phosphorylation and substrate-level phosphorylation, and identify when each occurs in cell respiration.
Oxidative phosphorylation uses the electron transport chain and occurs in the mitochondria, while substrate-level phosphorylation occurs during glycolysis and the Krebs cycle.
Both oxidative phosphorylation and substrate-level phosphorylation occur only during glycolysis.
Substrate-level phosphorylation uses the electron transport chain, while oxidative phosphorylation occurs during glycolysis.
Oxidative phosphorylation and substrate-level phosphorylation are identical processes that occur simultaneously throughout cell respiration.

The overarching chemical equation for cellular respiration is C6H12O6 + 6O2 → 6CO2 + 6H2O, and for photosynthesis it is 6CO2 + 6H2O → C6H12O6 + 6O2. In cellular respiration, glucose is oxidized and oxygen is reduced. Which of the following correctly matches the equations and the molecules oxidized/reduced?
Cellular respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O (glucose oxidized, oxygen reduced); Photosynthesis: 6CO2 + 6H2O → C6H12O6 + 6O2
Cellular respiration: 6CO2 + 6H2O → C6H12O6 + 6O2 (CO2 oxidized, water reduced); Photosynthesis: C6H12O6 + 6O2 → 6CO2 + 6H2O
Cellular respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O (oxygen oxidized, glucose reduced); Photosynthesis: 6CO2 + 6H2O → C6H12O6 + 6O2
Cellular respiration: 6CO2 + 6H2O → C6H12O6 + 6O2 (glucose reduced, oxygen oxidized); Photosynthesis: C6H12O6 + 6O2 → 6CO2 + 6H2O

they don't have an investment stage
they use a different type of glucose
they lack glycolysis
