answer: - ANSWER-Thylakoid membranes in chloroplasts
From this description, what do you think is most likely a major challenge in splitting
water for energy purposes? Select only the best answer: - ANSWER-Water requires
more energy to break apart than is recovered from recombining it
Knowing this, what is the relationship between the wavelength and energy of a photon?
Select the best answer below: - ANSWER-Shorter wavelength has higher energy
Light-dependent reactions are primarily for (select all that apply): - ANSWER-
Generating chemical energy (ATP)
Providing ATP and NADPH for the next phase of photosynthesis
Looking at the image to the right, which categories of light exist other than visible light?
Select all that apply: - ANSWER-Infrared
Radio
Gamma rays
X-rays
The Calvin Cycle reactions are primarily for (select all that apply): - ANSWER-Recycling
ATP to ADP and NADPH to NADP+
Energy storage (sugar)
Using the image as a guide, how do you think plants use the glucose they produce to
generate usable chemical energy (ATP)? Select all that apply: - ANSWER-By the
process of cellular respiration as in animals
It happens in the mitochondria of plant cells
Sugar gets broken down with the help of oxygen to release energy. Carbon dioxide,
water and energy are the results.
