Exam 8: Photosynthesis

Photosynthesis shows higher activity for violet/blue and orange/red and a lower absorption for green/yellow. If we could create a different photosynthetic pigment that absorbed absolutely all visible wavelengths of light, the leaves would appear which color?

The hydrocarbon skeleton used to form fatty acids, glycerol, and amino acids (when N is added) is derived from

Which of the following would be a reasonable explanation of why the chloroplast would use the cyclic electron pathway as well as the noncyclic electron pathway?

The formation of carbohydrate molecules occurs within the

Photosystem I comes before photosystem II in the noncyclic electron pathway.

At the cellular level, photosynthesis occurs within

What is the function of ribulose bisphosphate (RuBP) during photosynthesis?

NADPH and ATP are used in the

What pathway moves the electrons from water through PS II to PS I and then on to NADP⁺?

Most major food plants such as wheat, oats, and rice are

At night, plants cannot run metabolic pathways because there is no sunlight.

Which of the following allows photosynthetic organisms to capture solar energy?

During photosynthesis, CO₂ is reduced. This means that

Photosynthesis and cellular respiration utilize the same chemical pathways but in reverse of each other.

The flattened sacs within the stroma of a chloroplast, which are connected to form a single inner compartment, are called

Which of the following is a characteristic shared by cellular respiration and photosynthesis?

There is an inverse relationship between wavelength of light and amount of energy.

What are the stages of the Calvin cycle?

To what does the term grana refer?
