- Melvin Calvin and Andrew Benson determined the steps in the light-independent reactions of photosynthesis by exposing the green alga Chlorella to CO2 labeled with the radioisotope carbon 14. By looking at which compounds the C14 ended up in, they were able to identify all intermediates in this cyclic pathway. Why did they predict correctly that the same set of intermediates would be formed in the light reaction in land plants?arrow_forwardWhat color of light is least effective in driving photosynthesis?arrow_forwardTo assess photosynthesis, we relied heavily on a spectrophotometer to measure the color intensity of DCPIP in our solution. We set the spectrophotometer at wavelengths in the visible spectrum. What is the approximate wavelength range (in nm) for the visible spectrum? For example, the ultraviolet spectrum wavelength range is approximately 10-400 nmarrow_forward

- Which color light waves best at carrying out photosynthesis?arrow_forwardThe distinctly blue shade of a blue spruce results from the scattering of light by small waxy particles that coat the leaves. Explain how this scattering can protect the leaves from damage by short-wavelength ultraviolet light while still permitting the passage of longer wavelengths of light for photosynthesis.arrow_forwardWhy does darkness affect the light independent reactions of photosynthesis?arrow_forward
- You are cleaning your room and accidentally move your plant into the closet and forget about it for one week. a) Which molecules are not produced in the plant if light is not present? What effect do these molecules have on photosynthesis? b) Explain the effect of leaving the plant in darkness for one week on cellular respiration.arrow_forwardWhat is the overall outcome of the light reactions in photosynthesis? NADPH and ATP molecules are produced during the light reactions and are used to power the light independent reactions. NADPH and ATP molecules are produced during the light reactions, which are used to power the light dependent reactions. Sugar and ATP are produced during the light reactions, which are used to power the light independent reactions. Carbon dioxide and NADPH are produced during the light reactions, which are used to power the light dependent reactions.arrow_forwardIf you landed on a planet where all of the plants had purple leaves, what wavelengths of light would you expect to be least effective for photosynthesis? explain your reasoning.arrow_forward
