All rights 8 PhotosynthesisSection 8 1 Energy and Life(pages 201 203)This section explains where plants get the energy they need to produce also describes the role of the chemical compound ATP in cellular and Heterotrophs(page 201) does the energy of food originally come from?Energy in most food comes fromthe the table of types of Energy and ATP(pages 202 203) is one of the principal chemical compounds that living things use to store energy?

2 Adenosine triphosphate, or is ATP different from ADP?ATP has three phosphate groups, while ADP has two phosphate each part of the ATP molecule illustrated that make their own foodPlantsHeterotrophsOrganisms that obtain energy from Animals, mushroomsthe food they eatAdenineRibose3 Phosphate a cell has energy available, how can it store small amounts of that energy?It can add a phosphate group to ADP molecules, producing ATP is the energy stored in ATP released?It is released when ATP is converted to ADP and a phosphate OF ORGANISMS Pearson Education, Inc.

3 All rights _____ Date _____ Class what purpose do the characteristics of ATP make it exceptionally useful to all types of cells?All types of cells use ATP as their basic energy are two ways in which cells use the energy provided by ATP? within the cellATP and Glucose(page 203) is it efficient for cells to keep only a small supply of ATP on hand? ATP is not very good for storing large amounts of energy over the long term. A single sugar molecule stores more than 90 times the chemical energy of an ATP the letter of where cells get the energy to regenerate 8 2 photosynthesis : An Overview(pages 204 207)This section describes what important experiments revealed about how plantsgrow.

4 It also introduces the overall equation for photosynthesis and explainsthe roles light and chlorophyll have in the (page 204) occurs in the process of photosynthesis ?Plants use the energy of sunlight to convertwater and carbon dioxide into high-energy carbohydrates sugars and starches and photosynthesis (pages 204 206) did Jan van Helmont conclude from his experiment?He concluded that most ofthe mass a plant gained had come from water, because that was the only thing he had added tothe the letter of the substance produced by the mint plant inJoseph Priestley s did Jan Ingenhousz show?

6 It requires light and chlorophyll, a molecule in gather the sun s energy with light-absorbing molecules called . is the principal pigment of plants? the letter of the regions of the visible spectrum in whichchlorophyll absorbs light very regionChlorophyllpigmentssugarsReading Skill PracticeBy looking at illustrations in textbooks, you can help yourself remember better whatyou have read. Look carefully at Figure 8 4 on page 206. What important ideas doesthis illustration communicate? Do your work on a separate sheet of uses light energy to convert carbon dioxide and water into sugars and oxygen.

All rights _____Date _____Chapter 8, photosynthesis (continued)Light-Dependent Reactions(pages 210 211) the letter of each sentence that is true about the convert ADP into produce oxygen convert oxygen into carbon convert NADP+into do the light-dependent reactions take place?

9 Within the thylakoid membranes of the letter of each sentence that is true about the light-dependent electrons move through the electron transportchain from photosystem II to photosystem begins when pigments in photosystem I difference in charges across the thylakoid membraneprovides the energy to make in photosystem I use energy from light to does ATP synthase produce ATP?ATP synthase allows H+ions to pass through the thylakoid membrane. As the ions pass through, ATP synthase rotates, binding ADP and a phosphate group together to produce Calvin Cycle(pages 212 213) does the Calvin cycle use to produce high-energy sugars?

10 The Calvin cycle uses ATP and NADPH from the light-dependent reactions to produce high-energy are the reactions of the Calvin cycle also called the light-independent reactions?The Calvin cycle does not require the letter of each statement that is true about the Calvin main products of the Calvin cycle are six carbon dioxide molecules enter the Calvin cycle from from ATP and high-energy electrons from NADPH areused to convert 3-carbon molecules into similar Calvin cycle uses six molecules of carbon dioxide toproduce a single 6-carbon sugar Reading and Study Workbook/ Chapter 869 Pearson Education, Inc.
