MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. Use the following information to answer the questions below. Thomas Engelmann illuminated a filament of algae with light that passed through a prism, thus exposing different segments of algae to different wavelengths of light. He added aerobic bacteria and then noted in which areas the bacteria congregated. He noted that the largest groups were found in the areas illuminated by the red and blue light. 1) What did he conclude about the congregation of bacteria in the red and blue areas? A) Bacteria are attracted to red and blue light and thus these wavelengths are more reactive than other wavelengths.

Photosynthesis Energy Transformations ATP is the energy molecule used in all living things, so supplies must be constantly replenished. energy must be added to make ATP, thus ATP formation is an endergonic reaction. ADP + P + energy ---? ATP the addition of a phosphate molecule to ATP is called phosphorylation ATP ---? ADP + P + energy the removal of a phosphate molecule from ATP gives off energy and is called dephosphorylation Electron Transport System (ETS) is the means by which energy production occurs within cells. It is a series of progressively stronger electron acceptors. Each time an electron is transported, energy is either released or absorbed. This is how most of the ATP in plants and animals is formed Redox Reactions

Copyright ? 2011 Pearson Education, Inc. - 1 - Name_______________________Period___________ Chapter 10: Photosynthesis This chapter is as challenging as the one you just finished on cellular respiration. However, conceptually it will be a little easier because the concepts learned in Chapter 9?namely, chemiosmosis and an electron transport system?will play a central role in photosynthesis. 1. As a review, define the terms autotroph and heterotroph. Keep in mind that plants have mitochondria and chloroplasts and do both cellular respiration and photosynthesis! Autotroph: An organism that obtains organic food molecules without eating other organisms or substances derived from other organisms. Autotrophs use energy from the sun or from oxidation of

Photosynthesis Wednesday, March 06, 2013 11:00 PM ? Photosynthesis Photosynthesis - the process of converting energy in sunlight to energy in chemical bonds, especially glucose 6CO2 + 6H2O + light -> C6H12O6 + 6O2 Begins with light-absorbing pigments in plant cells A pigment molecule is able to absorb energy from light only within a narrow range of wavelengths In order to absorb as much of the entire bandwidth from sunlight as possible, different pigments, capable of absorbing different wavelengths, act together to optimize energy absorption These pigments include the green chlorophyll a and chlorophyll b and the carotenoids, which are red, orange, or yellow
