In Order to Understand the Driving Force of ATP Synthase

question 61

Multiple Choice

In order to understand the driving force of ATP synthase in chloroplasts, researchers broke open chloroplasts, isolated the thylakoid membrane and measured ATP synthesis under different light conditions. What were the results of this experiment?

• A) ATP production occurred only in light, suggesting that the light is directly responsible for the activation of ATP synthase.
• B) ATP production occurred only in light, suggesting that the light is indirectly responsible for the activation of ATP synthase.
• C) ATP production occurred only in dark, suggesting that the light directly inhibits ATP synthase.
• D) ATP production occurred only in dark, suggesting that the photons of light act as allosteric (non-competitive) inhibitors of ATP synthase.
• E) ATP production occurred only in dark, suggesting that the light is indirectly responsible for the activation of ATP synthase.

Definitions:

Confidence Interval

A range of numerical figures, deduced from the statistics of a sample, presumed to grasp the value of an indefinable population characteristic.

Standard Deviation

A measure of the amount of variation or dispersion of a set of values, indicating how much the individual values differ from the mean.

True Mean Yields

The actual average outcome or result produced over a particular period or through a series of processes.

Confidence Intervals

Statistical ranges, with a given probability, that are believed to contain the true value of an unknown population parameter.
