Accepted Answer

A) The cycle uses ATP and NADPH to produce sugars. 
B) The cycle moves electrons from Photosystem II to Photosystem I. 
C) The cycle moves light-energized electrons to Photosystem II. 
D) The cycle absorbs light from the light reactions. 
A) The cycle uses ATP and NADPH to produce sugars. 
B) The cycle moves electrons from Photosystem II to Photosystem I. 
C) The cycle moves light-energized electrons to Photosystem II. 
D) The cycle absorbs light from the light reactions.

Question 2

Light consists of massless particles called photons, each of which propagates through space with a wavelike oscillation; the ____________________ the wavelength the greater the energy content.

Accepted Answer

The answer of Light consists of massless particles called photons,...

Question 3

Biologists believe that Earth's early life-forms were exposed to an atmosphere with no molecular oxygen and had not yet evolved the Krebs cycle. If so, alcoholic fermentation would have been particularly critical to life because without the pathway

Accepted Answer

A) ethanol would not be available as a nutrient for other consumers. 
B) lactic acid would accumulate and disable prokaryotic muscle cells. 
C) carbon could not be recycled back into the biosphere for use by producers. 
D) the only source of NADH for electron transport would be from glycolysis and ATP production would be greatly reduced.

As an energy carrier, ATP differs from NADPH in that

Accepted Answer
