Gavin Morgan 11/9/2015 Chapter 8 2-Point Notes Photosynthesis combines CO2 and H2O, producing glucose and O2: 1. Photosynthesis takes place in three stages: capturing energy from sunlight; using the energy to make ATP and to reduce the compound NADP+, an electron carrier, to NADPH; and using the ATP and NADPH to power the synthesis of organic molecules from CO2 in the air. 2. In plants, photosynthesis takes place in chloroplasts: 1. The internal membrane of chloroplasts, called the thylakoid membrane, is a continuous phospholipid bilayer organized into flattened sacs that are found stacked on one another in columns called grana.

Overview: The Process That Feeds the Biosphere ? Photosynthesis is the process that converts solar energy into chemical energy. ? Directly or indirectly, photosynthesis nourishes almost the entire living world. ? Autotrophs sustain themselves without eating anything derived from other organisms. ? Autotrophs are the producers of the biosphere, producing organic molecules from CO2 and other inorganic molecules. ? Almost all plants are photoautotrophs, using the energy of sunlight to make organic molecules from water and carbon dioxide. ? Photosynthesis occurs in plants, algae, certain other protists, and some prokaryotes. ? These organisms feed not only themselves but also the entire living world. ? Heterotrophs obtain their organic material from other organisms.

Mica Piro Chapter 10: Photosynthesis The Process That Feeds the Biosphere The conversion of light energy from the sun to chemical energy stored as sugar is called photosynthesis (occurs in algae, certain other unicellular eukaryotes, and some prokaryotes) Nourishes almost the entire living world directly or indirectly Organism acquires the organic compounds it uses for energy and carbon skeletons by one of 2 major modes: autotrophic nutrition or heterotrophic nutrition Autotrophs (?self-feeders?) sustain themselves without eating anything derived from other living beings Produce their organic molecules from CO2 and other inorganic raw materials obtained from the environment

Chapter 10: Photosynthesis ?Photosynthesis is the process that converts solar energy into chemical energy ?Directly or indirectly, photosynthesis nourishes almost the entire living world This chapter is as challenging as the one you just finished on cellular respiration. However, conceptually, it is a little easier because the concepts learned in Chapter 9: Chemiosmosis, and an electron transport system 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.

Chapter 10 notes Photosynthesis Photosynthesis In Nature All life acquires organic compounds for energy and carbon skeletons by one of two ways - ______________: (autos = self, trophos = feed) - they sustain themselves w/out eating other organisms Photosynthesis In Nature - plants are _________________ because they use light as a source of energy - __________: (hetero = other, different) - live on compounds produced by other organisms Heterotrophs are dependent on photoautotrophs for food and oxygen Photosynthesis In Nature ________________ are the site of photosynthesis in plants All green parts of plants have chloroplasts - color is from ____________, the green pigment in the chloroplasts

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
