Question

1.) As a research scientist, you measure the aomount of ATP and NADPH consumed by the Calvin cycle in 1 hour. You find 30,000 molecules of ATP consumed, but only 20,000 molecules of NADPH. Where did the extra ATP molecules come from? How does photosynthesis obtain these different amounts of product?

2. ) Assue a thylakoid is somehow punctured so that the interior of the thylakoid is no longer separated from the stroma. This damage will have the most direct effect on which cellular process? Be specific. After an amount of time has passed, how will this affect the Calvin cycle?

3.) How does a bacteria living in a high temperature environment near a hot spring survive? What would happen to human cells in the same conditions?

Explanation / Answer

1.) The extra ATP molecules come from cyclic electron flow.

photosynthesis obtains these different amounts of products through a series of biochemical reactions.

2.) The damage will have the most direct effect on the synthesis of ATP

The calvin cycle will malfuntion because ATP is the main source of energy for calvin cycle.

3.) Bacteria living in a high temperature environment near a hot spring survive is known as hyperthermophile. The protein molecules in the hyperthermophiles exhibit hyperthermostability that is, they can maintain structural stability (and therefore function) at high temperatures. The cell membrane contains high levels of saturated fatty acids to retain its shape at high temperatures.

A human will most likely experience heat stroke in such conditions.
