11. (a) The shorter the wavelength, the greater the energy; therefore, a shorter wavelength has
more energy.
(b) Plants can use wavelengths from 380 to 480 nm and from 620 to 680 nm in
photosynthesis.
12. (a) Old textbooks often referred to the Calvin cycle as “the dark reaction” because it did not
appear to require light to occur.

Part 2
9. During the light-dependent reactions of photosynthesis, light energy is absorbed by
photosynthetic pigments and then transferred to the electron carrier, NADPH, and ATP is
synthesized because of the buildup of a proton gradient, driven by the splitting of water
molecules.
10. The equations of photosynthesis and aerobic respiration are the reverse of each other. The
difference is the energy involved. Solar energy is the type used in photosynthesis. ATP is the
energy produced in cellular respiration.
A great Animation to use as a reference as you create your stop motion project!

Reverse ageing by boosting cells' energy factories
Reverse ageing by boosting cells' energy factories
Just as a car's battery wears down with age, mitochondria, our cellular powerhouses, produce energy less efficiently as we get older. Now, aging mice have been given a new lease of life after being injected with a drug that jump-starts their mitochondria. New Scientist, 9/27.
JUST as a car's battery wears down with age, mitochondria, our cellular powerhouses, produce energy less efficiently as we get older. Now, ageing mice have been given a new lease of life after being injected with a drug that jump-starts their mitochondria.
Mitochondria contain genes coding for proteins important in energy production. So Shaharyar Khan of Gencia Corporation in Charlottesville, Virginia, and colleagues wondered if boosting the activity of these genes might reverse decline.
They took a naturally occurring mitochondrial transcription factor called TFAM, which initiates protein synthesis, and engineered it to cross into cells from the bloodstream and target the mitochondria.
Aged mice given modified TFAM showed improvements in memory and exercise performance compared with untreated mice. "It was like an 80-year-old recovering the function of a 30-year-old," says Rafal Smigrodzki, also at Gencia, who presented the results at the Strategies for Engineered Negligible Senescence conference in Cambridge this month.
Surprising Findings On Hydrogen Production in Green Algae
Surprising Findings On Hydrogen Production in Green Algae
Apr. 12, 2013 — New research fuels hope of efficient hydrogen production with green algae being possible
in the future, despite the prevailing scepticism based on previous research. The study changes the view on the potential of green algae – which is good news. The world must find a way of producing fuel from renewable energy sources to replace the fossil fuels. Hydrogen is today considered one of the most promising fuels for the future and if hydrogen can be produced directly from sunlight you have a renewable and environmentally friendly energy source. One biological way of producing hydrogen from solar energy is using photosynthetic microorganisms.
