- Q1Which of the following is NOT a part of an ATP molecule?ribosechlorophylladenine30s
- Q2Which structures shown in Figure 8-1 make up an ATP molecule?C and DA, B, C, and DA and B30s
- Q3Organisms that cannot make their own food and must obtain energy from external sources are called:heterotrophsthylakoidsplants30s
- Q4What happens during photosynthesis?Heterotrophs produce ATPHeterotrophs consume ATPAutotrophs produce carbohydrates30s
- Q5Plants get the energy they need for photosynthesis by absorbing:sunlightchlorophyll ahigh-energy sugars30s
- Q6Most plants appear green because chlorophylldoes not absorb violet lightabsorb green lightdoes not absorb green light30s
- Q7A granum is astack of thylakoidsmitochondriaplant cells30s
- Q8The stroma is the region outside the:thylakoidsplant cellschloroplasts30s
- Q9Where in the chloroplast is chlorophyll found?in the stromain the thylakoid membranein the ATP30s
- Q10What makes certain molecules good electron carriers?They are carbohydrates and have a lot of energy, which allows them to carry electronsThey can accept electrons and transfer most of their energy to another moleculeThey can absorb sunlight, which is where all of the high-energy electrons come from30s
- Q11Which of the following is NOT found in the overall reaction for photosynthesis?nitrogenwaterlight30s
- Q12In the overall equation for photosynthesis, six molecules of carbon dioxide and six molecules of water result in a molecule of sugar and six molecules of:oxygenATPwater30s
- Q13Where do the light-dependent reactions take place?in the stroma of the cholorplastwithin the thylakoid membranesin the outer membrane of the chloroplasts30s
- Q14Which of the following is NOT a step in the light-dependent reactions?High-energy electons move through the electron transport chainPigments in photosystem II absorb lightATP and NADPH are used to produce high-energy sugars30s
- Q15What action contributes to the inside of the thylakoid membrane becoming positively charged during the light-dependent reactions?H+ ions are released as water splitsCarbon dioxide builds up in the stromaATP synthase allows H+ ions to pass through the membrane30s
